CAP 203 - Computer Animation III

Chapter 28 - Advanced Lighting

Objectives:

This lesson introduces new information about lighting in 3DS Max. Objectives important to this lesson:

  1. Light tracing
  2. Radiosity
  3. Outside tutorial
Concepts:

The chapter begins a new lesson on lighting. Two new features are introduced, Light Tracing and Radiosity. Light Tracing is described as being useful for simulating sunlight outdoors. Radiosity is is described as an advanced system for more realistic lighting than we have used already that requires tweaking of several settings.

Either lighting system can be selected from the rendering dialog panel, on the Advanced Lighting tab.

Assignment:

  1. The text offers a short tutorial with a hotplate to demonstrate the Light Tracing feature. (I know, they said sunlight, and they show us a glowing hotplate.)
  2. The demonstration is not clear until you combine the Viewing color bleeding tutorial with the Excluding objects from light tracing tutorial. Carry out the steps on page 675, then the steps that start on page 676.
  3. Try several different values for Bounce. Describe the difference it makes.

The chapter moves on to decribe Radiosity as a system that simulates light bouncing off objects in a scene and continuing to illuminate other objects. Each bounce reduces the intensity of the ray of light, as it does in the real world.

Follow this link to another tutorial that describes setting up lights and using Radiosity in a 3DS Max 9 scene.
