Customizing System
Additional flag “Disable Workplane Transparency” turns off the mode of semi-transparency of
workplanes in 3D window (no matter what the settings in the parameters of the workplanes themselves
are). With the flag turned on, all workplanes are displayed as transparent.
The flag “Cache 3D objects” controls caching the objects on the 3D scene. When set, the sequence of
OpenGL instructions is kept in a designated area of computer RAM and is updated only on changes in the
3D window. This may speed up redraw of the 3D model on low-performance graphic cards. When this flag
is unset, more memory is used by the application.
Complete redraw. When unset (default), the image redraw relies on an optimization procedure. In this case,
the image in the 3D view window is redrawn completely only when the model is changed or moved. As a
result, it is possible that moving some tool window across the screen leaves traces on the 3D view window.
Setting the discussed flag turns on the complete redraw mode. In this case, the model image in the 3D view
window is redrawn on each screen refreshing. This helps get rid of the mentioned flaws. However, redraw
of complex models slows down.
Changes to OpenGL settings take effect only after opening a new 3D window.
Rendering Simplifications
Desired FPS rate. This parameter has a separate value for each of
the following modes:
- Dynamic picture
- Automatic rotation
- Static picture
If the detailed image of the model can’t be generated within the
frame duration, the system will identify the ways to simplify the
image. Given bodies (their images) are drawn in a simplified
manner as parallelepipeds. Thus the whole model image is being
simplified until the frame generation time falls within the frame
duration period per the required frequency of screen redraws.
Temporary simplification of the image for
easier rotation of the model in 3D window
Normal view, generated by more powerful
video card
Reduce transparency quality. If this flag is set, then the system will automatically reduce the quality of
transparent surface rendering in the case image simplification is necessary. This will be done regardless of
the “Transparent object rendering” parameter setting under OpenGL. This means, in order to speed up
display, the quality of transparent surfaces may go down. However, this would occur only when the frame
output frequency falls below the “Desired FPS rate” setting.
