Relief design ReliefVTR.

Reliefs
are calculated in ReliefVTR from 2D line graphics. The work sequence for
finished milling data, as a rule, consists of the following steps:
1
|
2D
path creation (Line design) in the CAD.
|
2
|
Conversions of paths into spatial
relief data in ReliefVTR.
|
3
|
Calculation of milling paths from the
created relief.
|
Design on background graphic.
If
a specified graphic (photo) is to be revised, then it can be worked in the background in the CAD and the necessary line graphic drawn over this.
Colour and b/w photos are best save in a .jpg file and loaded in the CAD
using the aid Graph background .
Load backgr-image. When saving, take note of the correct dimensions (measurements)
of the photos. JPG images are loaded in the background with the saved
measurements.
In
the
CAD draw your contours and sections over this photo.
Best detected on the background are graphics with the light layer colours
(Layer#6..10). In suitable images contours can also be sought using
Edit Relief
. Layer border. The lines and contours created should sensibly already
be shared out to layers. The Layer #15 is reserved as storage for ReliefVTR and my not be used in the CAD. You can generate
a 3D shape from the paths in the CAD using ReliefVTR. For further
drawings an editing in the CAD you can choose between Backgr-image
and Relief
as background.
Note: The border
search in photos using
Edit Relief . Layer border is frequently difficult, because photos are
usually spotty. Improvement can be achieved by smoothing the images using Edit
relief . filter. Here you should attempt the smoothing using the
functions Error pixel, Outlier and
approximate. As far as no experience is available, the functions
can be applied one after another in the listed order.
Relief
creation.
For relief creation in ReliefVTR
first an empty relief is created using New relief. Here you should leave the
proposed settings for the draft phase unchanged. With this,
a coarse image is created,
which can be edited quicker. Only with the final relief creation do you
set the relief resolution to the desired size. For very deep reliefs
please also observe the relief Z range (depth (Z)). This is preset to
10mm and suffices for normal reliefs in medallions and jewellery range. If
the relief with this setting exceeds range from +/- 32mm, then errors are
to be expected. If deeper reliefs are planned, then the Z range should be
set correspondingly greater. On the other hand with greater depths the Z
resolution and thus the quality are reduced.
All
reliefs for relief creation are assigned to the objects (paths). You can
reselect, modify an object at any time and, using the adjusted object data,
create a new relief very rapidly. Important for the creation of reliefs
from 2D paths is a precise idea of the work sequence, because, with the
relief creation, in addition to the 3D geometry the
linkage
logic (sequence) is important. If, for example, a coin/medal is to be
created then first all tasks in the flat area are finished and finally the
sphere for a convex
surface is created.
For relief creation marked
the desired contours in the CAD and
with this change into the ReliefVTR menu. If the same paths are
required for several paths (e.g. mirror + inclined surfaces), the
it is sensible to
create a copy of the paths before the change to ReliefVTR. For this,
copy your paths into an empty layer, mark the contours in this layer and
change to ReliefVTR. Following the relief creation (allocation of
the relief characteristics) these contours are adopted in the object list
for the relief creation and are no longer available for the immediate CAD
operations. Mark
only the paths for a relief object.
With too many paths one easily loses the overview. Also, not all selection
possibilities of the CAD are available in ReliefVTR. If the paths are
converted in the desired fashion, then change into the CAD ,
mark the next paths and go with these to ReliefVTR etc.
Fundamentally it is not permitted to copy or edit data from Layer#15.
If the now created relief corresponds with your ideas and if all editing
tasks are completed, then you can have the final relief created. For this
set the resolution
in new relief in the final dimensions (e.g. 0.02mm for coin
relief; 0.1mm for wood work etc.) and have the relief calculated using
new create. With high resolutions and large measurements this can,
under certain conditions can take a long time. Because this procedure runs fully,
this not so crucial.
The relief resolution.
You achieve favourable conditions if milling resolution (milling track
separation) and relief resolution are in agreement with each other or if
the relief resolution lies at
2-..4 times the milling resolution. You can save considerable calculation
time if you avoid unnecessarily high relief resolution and match this to
the milling resolution.
Points in grid format similar to the image data PCX, TIFF, BMP
etc. are saved in relief. This format is very suitable for the creation of
3D image data for normal reliefs with high resolutions. For large
tasks, limits can, however, also be exceeded rapidly which greatly reduces
the working rate. Therefore reliefs with a scope of more than 10 million
points should be avoided . The calculation and milling correction of a
relief10 million points even with very quick computers still
requires considerable computer time.
The relief data amount is dependent on the X and Y measurement and the
point separation. Thus, for example, for a relief of X = 50 mm and Y = 50 mm
with a point separation of 0.05mm, 1million points are created. With
a point separation of 0.02mm and same measurements these are already
6.25 million points. The data created for your relief (position,
measurements and resolution) are displayed using Relief file . Status.
If fine structures are to be created, then the relief must be set naturally
at the appropriate resolution. If, for example, a line with vertical flanks
and with a width of 0.1mm is drawn, the relief must be created with a
minimum resolution of 0.1mm, better however, with 0.05mm. If this line is also
rounded-off then the resolution must be set once again higher. In a case of
doubt check the achievable relief quality using a number of sample lines.
On the other hand, relief resolutions smaller than 0.02mm are barely
sensible because the realistically achievable tools
are barely capable of dealing with this measurement.
Note:
Due to the point separation a vertical flank (milling steepness) can never
be achieved.
Relief
design.

With
ReliefVTR designed relief table
To work with ReliefVTR, for the best results use the icon menu
for a rapid change of the program modules. The program module can be
selected in the icon menu with a click from the CAD. From ReliefVTR
you access the CAD also in the icon menu by clicking-on file,
CAD or CAM.
In
ReliefVTR a relief can be created, modified and combined from
previously provided vector data though object allocation. Thus, for
example, vector lettering and drawings as well as surfaces can be
installed in relief. Individual areas can be raised, lowered or deleted
through addition,
subtraction etc. Surfaces can be filled planar
at any desired level. For the borders a
formable surface relief run an be employed. The functions in ReliefVTR
are completely object-oriented. The individual objects can be edited freely
at any time. or can put together a relief from sections and contours with
allocated characteristics and from other reliefs (comp. Relief
File . Export extract and Export frame). In addition to the
complete creation of reliefs from vector data an existing relief can be
modified, using the functions, for example through addition of surfaces,
lettering etc.
Some of the functions in ReliefVTR use surface relief runs. These
runs are referenced and not tied to the data. The surface relief runs are
saved automatically in the PROJECT
directory.
Objects with characteristics are saved in Layer#15. Although these
paths could be worked in the CAD, created
objects should not be modified directly in the CAD, because through
this the characteristics are lost. If you wish to revise the paths of an
object, then produce a copy using ReliefVTR . Copy, object,
modify this and readopt the object in exchange object.
The ReliefVTR menu breaks down into the areas
-
create objects (insert slopes .. relief),
-
edit objects (edit object ..
exchange object) and
-
relief aspect (relief position ..
render),
-
adjust and create reliefs (new relief, newly create).
Work steps for relief design.
1
|
Create vector data (paths) in the CAD (by scanning,
engineering etc.). You can also scan-in a photo, import as relief,
place in the background and draw over it. Please not that for some
objects closed contours are demanded.
|
2
|
Mark the vector data and change into the ReliefVTR menu. The
vector data are now displayed in blue-green.
|
3
|
Create an empty relief using New relief. For the draft phase
leave the relief resolution (resolution [mm]) in
the proposed size.
|
4
|
Select the desired object and according to requirement click-on the
associated vector data. The vector data are now marked in red.
Input and create objects completely.
Thereafter the paths are marked in magenta.
|
5
|
As required edit objects.
|
6
|
Finally, for increased resolution, finally calculate the relief
using New relief.
|
Create relief objects.
Using the following functions and using simple means create relief objects
from contours, sections, surfaces and reliefs. All objects can be linked
with the background (the already existing relief) using logical operations (ADD, SUB, COPY, AND, OR).
For this reason, under certain circumstances, it is important also to
define the sequence clearly in addition to the geometry. The
logical operations are explained under Relief
linkage.
The
relief linkage (Logic).
The object is linked logically to the already existing relief (background).
Depending on the type of object some linkages are not available. The most
important linkages are ADD (+), SUB (-), COPY and
OR (max).

|


Emboss effects of the relief linkage (horizontal
fields). Incised under background (horizontal fields). The examples
for AND (clr) are always created separately. |
ADD
(+)
|
The new relief point is added to the background.
|
SUB
(-)
|
The new relief point is subtracted from the background (incised).
|
COPY
|
The new relief point is set at the position of the background - the
previous content is overwritten (replace).
|
AND
(min)
|
The new relief point is linked with the background UND - i.e. the
height, which is jointly held in both is placed (the smaller value
is adopted).
|
OR
(max)
|
The new relief point is linked to the background OR - i.e. the
greatest value is adopted. The height is available in the background
or in the object.
|
-OR
(min)
|
Subtraction
and/or linkage (incised OR).
|
SCALE
(mult)
|
Multiply the background with the object (scale).
|
AND
(Clr)
|
Stamp out the background with the object in 3D.
|
Inverse
|
The background within the object is inverted (mirrored in Z)
(only in combination with border and plan without border).
|

|
|
Active/
Inactive
|
Create/do not create object. Using this function an object can be
temporarily deactivated in the editing phase, i.e. with create
relief this object is not taken into account for the relief
calculation.
|

Newly input objects, following their complete definition, are entered into
the existing relief using create and are thereafter immediately
visible.
If existing objects are edited, then the settings can be fixed using
adopt. If these modifications are to be visible, the after this the
relief must be completely built up using Create new.
Surface
relief run.
Some functions in ReliefVTR employ surface relief runs. The surface
relief runs must be available as file. For this, the sections created here
are saved (in the directory PROJECT
) before their first application. With the functions File . Project
new/ open / save you have the possibility of ensuring a task
completely with all associated data.
Polylines may possess no re-entrant angles. The polyline run for surfaces
differs fundamentally from the run for sections. The surface run is always
formed from the contour inwards and usually has an upward progression. The
section run is projected to the right and left from the section, has its
highest point usually in the middle and a falling progression. For the
surface relief input the program automatically selects the correct input
form. For the intersection selection the user must determine the correct
run.

Slants 3/4Pkt.
|
The areas limited by contours are converted into slant
relief areas. The contours for which a relief surface is to be calculated
must be selected using the cursor. The surface is determined by 3
points (P1, P2, P3) or by 4 points (P1 .. P4) in X, Y and Z.
The points may not lie on a line and should enclose an as large as
possible surface.

file . Export extract or Export
frame. The relief to be inserted can be
freely positioned and adjusted with (position,
size, distortion, rotation, basic height, mirror, logic).

LINE-Grav Param.
|
Using
LINE-Grav 3D lines can be drawn directly in
the relief. The input supports both the
normal Mouse input and also the scroll Mouse
input. For the input of 3D
lines both functions LINE-Grav Param
(settings for LINE-Grav) and LINE-Grav input
(line input)
are required.

|
Parameter
presetting for the direct input of 3D
lines.
|
Run:
|
Shape of the edge or the line. The run is
adjusted in the input Surface
relief run. The run is projected towards the
right and left of the section and has its highest point in the
middle. With this, the runs for sections differentiate fundamentally
from the runs for surfaces. Surface runs, as a rule, have an
increasing progression, runs for sections have a decreasing
progression.
|
Edit
Parameters:
|
Limiting value input for the drawing of the 3D
lines.
Z maximum:
|
Limiting value for the adjustable Z
current value. This limit cannot be
exceeded in the input.
|
Z current:
|
Z value for the line input.
During input the Z value can increased in steps using <F3> in
steps (setting Z
step) or decreased using <F4>.
|
Z step:
|
Step width for the increasing/decreasing
using <F3>
and <F4>.
|
|
Input:
|
The line can be input as position sequence (Posn.),
free-hand line (FreeH.)
or as spline support points (Spline).
|
Logic:
|
In
general operations are only with the logic ADD (build
up) or SUB
(remove).
|
LINE-Grav Input.
|
Direct drawing of 3D lines
and creation of the relief sections.
For input the line can be directly drawn. The Z
values are displayed on the cursor. During the
Mouse input the Z value can be modified in steps using <F3>
and
<F4>. The settings for the line
creation takes place using LINE-Grav Param.
If
a 3D line is clicked-on for editing using Edit
object,
then the edit window is opened. The 3D
line can be adjusted here.

|

|
Run:
|
Shape of the edge or the line. The run is
adjusted in the input Surface
relief run. The run is projected towards the
right and left of the section and has its highest point in the
middle. With this, the runs for sections differentiate fundamentally
from the runs for surfaces. Surface runs, as a rule, have an
increasing progression, runs for sections have a decreasing
progression.
|
Ends:
|
Sections can end straight or rounded-off.
|
Basic height:
|
Offset
in Z direction for raising or lowering. The basic height can
be input directly manually or following <M>, <F2>
selected in the relief.

|
All points of the line are shown in the editor and
can be modified here. The format
of the list (sequence and configuration) may not be modified.
|
Scale /smooth.
|
A
surface is scaled with the level and smoothed
according to the run and the smoothing radius (environment) smoothed.
Smoothing is within the contour, i.e. parts lying outside remain unchanged.
Limiting contours must be selected for
scaling/smoothing.

|

Relief without and with smoothing in the area of the border. |
Level:
|
Scaling
factor for the surface. Values smaller
than 1 reduce and
values greater than 1 increase the Z values of the relief
within the contours. Level =
1 produces no change.
|
Run:
|
Effect of the environment on the smoothing.
NO:
|
No run, i.e.
the smoothing effects all points
within the smoothing radius. The
smoothing begins immediately at the limiting contour.
|
Linear:
|
Linearly
increasing smoothing effect within the smoothing radius.
|
Radius:
|
Increasing smoothing effect with radial run within the
smoothing radius.
|
Parabola:
|
Increasing smoothing effect with parabolic run within the
smoothing radius.
|
Cubic:
|
Increasing smoothing effect with cubic run within the
smoothing radius. Standard
setting.
|
|
Smooth radius:
|
The area to be taken into account around the point to be smoothed.
A small smoothing radius produces small smoothing effect, a large
smoothing radius a large smoothing effect.
|
End section:
|
Through the runout area
the smoothing is reduced towards the edge. Directly
at the edge there is no smoothing.
With this unattractive relief modifications can be avoided or at
least reduced in the edge area. The edge
runout area changes the smoothing process
in such a way, however, that irregular effects can occur. These effects can occur clearly in some relief
forms and cannot be avoided. If
these irregularities are very disruptive, the runout area
must be significantly reduced or be done without completely.
The runout area should
not be selected greater than the smoothing radius, better still
significantly smaller.
|
Surface/ contour
band/ section:
|
Surface effect of the smoothing process.
Surface:
|
The smoothing acts
within the given contours.
|
Contour band:
|
The smoothing acts
within
a band with the separation smoothing
radius to both sides.
|
Section:
|
The smoothing acts
along the section.
|
|
Edit object.
|
Each object can be selected by clicking-on its paths (contours,
sections, points) for
editing. Here only already selected objects (display
in magenta) are
marked. If objects lie congruent to each other,
then these can no longer be differentiated using the cursor. For
this case the selection using Seek object
helps further. After clicking-on the
characteristics of the object are displayed (comp.
input for the objects). The
characteristics can be modified within the described limits.
With adopt the
new object characters are secured. If a modified
graphic is desired the graphic structure must be started using
recreate.
Seek object
|
With
Seek object
an alternative method
is available for the selection of the object.
The sure selection of some objects using the cursor
is, in part, difficult, for example, if objects
lie congruent. To Seek object belong the selection for the further
switching of the current object,
the object list and the marked paths in the graphic. The selected object
is marked in the graphic and emphasised in red in the list.

|

|
Object
#:
|
Display and input of the current serial
object number.
|
First:
|
Selection of the first object. The current object is marked in red
in the object list and in the graphic.
|
Last:
|
Selection of the last object. The current object is marked in red in
the object list and in the graphic.
|
One forwards:
|
Switch forward one object. The current object is marked in red in
the object list and in the graphic.
|
One backwards:
|
Switch back one object. The current object is marked in red in the
object list and in the graphic.
|
Edit:
|
Editing
of the selected object (comp. Edit object).
|
Object
sequence:
|
Modify the sequence of the selected object in object order
(object list) (comp Object sequence).
|
Clear
object :
|
Delete the selected object (comp. Object clr).
|
Copy object :
|
Copy the paths for an existing object. Thereafter these are
available as marked paths (comp. Copy object).
|
Exchange object:
|
Replace the paths of an existing object with new paths (comp.
Exchange object).
|
Object sequence
|

|
Along with the geometric configuration
of the object in the space, the sequence of the object creation is
also of relevance and must be observed closely. Here you can modify
the sequence of the objects
(first, last, one forward/back, reverse). To the Object sequence
belong the selection for the further switching of
the current object,
the object list and the marked paths in the graphic. The selected object
is marked in the graphic and emphasised in red in the list.
|
At
posn #:
|
Input in the object sequence.
|
First:
|
Displace
the selected object at the first position in the list.
|
Last:
|
Displace
the selected object at the last position in the list.
|
One forwards:
|
Displace
the selected object in the list one position forwards.
|
One backwards:
|
Displace
the selected object in the list one position backwards.
|
Reverse sequence:
|
Completely reverse the object sequence.
|
Adopt:
|
Adopt the input of the object sequence and end the input.
|
Object clr.
|
Using Object
clr you can delete an object with allocated characteristics and restore the
path. The restored paths are adopted marked in the ActLayer after quitting
the relief module.
Abort:
|
Abort the selection.
|
Object:
|
The restored contours are adopted in the ActLayer
after leaving the relief
module.
|
Object
+ paths:
|
Deletes the object and the
associated paths (contours,
sections).
|
Copy object .
|
Restore a copy of the object paths. The
restored paths are adopted after quitting the relief
module in the ActLayer.
This function is
helpful, if the paths for a further object are again required or if the
paths are modified a further object is to be created.
For modifying (editing,
correcting,...) the object paths first create a
copy using Copy object,
revise the paths in the CAD,
mark the modified paths and adopt these again in ReliefVTR.
Using Exchange object
the old paths can then be replaced by the new modified paths (exchanged).
Exchange object.
|
The paths of the selected object are replaced by
new paths to be selected. First, you must call
up the paths of the old object, after this the new paths are to be marked.
If, for the object, several paths contours, section) be replaced, then
the paths can be combined in the CAD beforehand.
For modifying (editing,
correcting,...) the object paths first create a
copy using Copy object,
revise the paths in the CAD,
mark the modified paths and adopt these again in ReliefVTR.
Relief Position.
|

Shows the relief
coordinates at
the cursor position.
Displayed as the background is the pixel colour,
as numerical value the position and
the Z value of the p. <R> or <Esc>
ends the display.
X/Y/Z:
|
Relief position
in mm.
|
A/B:
|
Ascending slope
in deg. at the relief position for
the directions A (rotation about the X
longitudinal axis) and B (rotation
about the Y longitudinal axis).
An angle of 0° describes a flat run, a
right angle a vertical run (is not achieved).
The angle is measured via 3 relief points (interpolated).
Thus a vertical run (90°) is not
achievable.
|
Relief height line.
|

The relief height line in the horizontal
direction at the cursor position
is displayed in the window at the upper edge of the image.
Display is ended using <R> or <Esc>.
Show level.
|
A

|
New relief.
|

|
Input the data for a new relief and
create an empty relief. Tasks in ReliefVTR are
normally drafted and edited in the resolution proposed in the
program. The proposed resolution ensures a
sufficient quality together with rapid sequence of operations. If
all objects are completely arranged, the
resolution can be increased to the desired degree and the relief
can be recreated.
|
Resolution
[mm]:
|
Resolution of the relief in X and Y
direction. For
the draft phase
it is recommended to retain the resolution proposed by the
program. The resolution should first be
increased for the calculation of the finished relief.
Normal settings are then ca.
0.01mm-0.1mm.
|
Depth
(Z) [mm]:
|
Extension of the relief in the Z direction.
The depth (Z) should
not be significantly exceeded because, otherwise, one has to reckon
with overrun and erroneous results.
|
ReliefObj-Layer#:
|
Selection of the layers, in which the relief object
is to be saved.
Standard setting = 15.
|
Recreate.
|
Recreate the relief using the settings in
New relief
and the objects. A
relief must be created after the characteristics
of a relief have been modified or, for example,
after modification of the resolution at the
final relief.
