Lighting Analysis
How to use the lighting analysis
tools to evaluate your design.
Lighting analysis provides valuable design information if you use real-world
lighting and materials in your scene. Use lighting analysis to evaluate the
photometric performance of your scene.
Summary
In this chapter, you learn about:
• Displaying light distribution
• Analyzing lighting statistics
• Controlling analysis grids
• Using workplanes.
About Lighting Analysis
After you run the radiosity process, use lighting
analysis to visualize the distribution of light over the
surfaces of your model. You can query either lumi-
nance or illuminance and visualize the distribution
of these quantities for any surface.
You view the distribution of light using pseudo-
coloring techniques or by superimposing a grid of
illumination values over a selected surface.
Displaying Light Distribution
Pseudo-coloring techniques are used to illustrate the
distribution of light directly onto the surfaces of a 3D
scene. You modify how this information appears
using the Display panel of the Lighting Analysis
dialog.
