The renderer is a general-purpose renderer that generates physically correct
simulations of lighting effects, including ray-traced reflections and refractions,
and global illumination.
A range of standard rendering presets, reusable rendering parameters, are
available. Some of the presets are tailored for relatively quick preview
renderings while others are for higher quality renderings.
Quick Reference
Commands
RENDER
Creates a photorealistic or realistically shaded image of a 3D solid or surface
model.
RENDERENVIRONMENT
Controls visual cues for the apparent distance of objects.
RENDERWIN
Displays the Render window without starting a rendering operation.
SAVEIMG
Saves a rendered image to a file.
Prepare a Model for Rendering
The way a model is built plays an important role in optimizing rendering
performance and image quality.
Understand Face Normals and Hidden Surfaces
There are several steps commonly taken to speed up the rendering process.
In order to minimize the time it takes to render a model, it is common practice
to remove hidden surfaces or hide objects that are positioned off-camera.
Furthermore, ensuring that all face normals orient in the same direction can
also speed up the rendering process.
Every surface that you model is made up of faces. Faces are either triangular
or quadrilateral and each face has an inward and outward oriented side. The
