Background Positioning

The Background Wizard makes it easy to position your rendered model in a background, and to remember the settings for future renderings.

In this sample, we loaded a background image which did not match the perspective of the current AutoCASD view.\

By loading the background wizard, we are able to see the background image both behind the AutoCAD view, and through the transparent windows. By dragging the handles on the background image, we can get the matching we want.

And then, we we re-render the model, we get a background which aligns with the current view.

  • Background Positioning
These values show the offsets and scales which are applied to the rendering engine when positioning the background.
  • Maintain Aspect Ratio
if this is checked, then the when stretching the image, the original aspect ration will be maintained.
  • Distortion
  • Off - Background is always rectangular
  • Perspective - Right and Left side can be expanded or reduced to product a perspective effect.
  • Full - all four corner points can be changed independently
  • Reset Position
Resets to the default scale and offset
  • background Image filters
Apply some simple filters to the background image.
  • Zoom Background Images
Zoom,In, Soom Out, Zoom All, Zoom to rendered area only
  • Show only render area
When not checked you can see the full background image, outside of the rendered image, and use the handles to stretch or scale the background.
  • Show model as Wire-frame
This can make it easier to see the background image behind the model.
  • Opacity
Makes the AutoCAD image more transparent so you can see the background better behind it.
