Using Materials
How to define and apply
materials to surfaces.
Materials determine the appearance of a surface, as well as the amount of light
that it reflects into the model. Use materials to add color and texture to surfaces.
Summary
In this chapter, you learn about:
•
Material properties
•
Using the Materials table
•
The Materials workflow
•
Adding materials to your scene
•
Editing material properties
•
Assigning materials to surfaces
•
Aligning textures.
About Material Properties
Because Lightscape is based on physically accurate
simulation techniques, it is important to provide
accurate physically based material specifications to
obtain accurate results.
The properties that determine how a material inter-
acts with light are:
•
Color
•
Transparency
•
Shininess
•
Refractive index.
Color and transparency determine the diffuse
lighting (direct and indirect) that is computed
during the radiosity process.
Refractive index and shininess determine the high-
lights and specular reflections of the surfaces in your
model. Highlights and reflections are rendered
during ray tracing.
