These are procedurally generated, based on the local axis of the object.
■ Face-mapped materials
The maps are placed based on the facets in the geometry.
Maps
Front left sphere: Marble bitmap
Front right sphere: Clouds bitmap
Back left sphere: Noise procedural map
Back right sphere: Marble procedural map
The images you assign to materials are called maps. The software provides
several different map types. They include standard bitmaps (such as .bmp, .jpg,
or .tga files) , procedural maps, such as Checker or Marble , and
image-processing systems such as compositors and masking systems.
You can assign maps to most of the components that make up a material.
Materials that contain one or more images are called mapped materials. By
assigning maps to different attributes of the materials, you can affect the color,
the opacity, the smoothness of the surface, and much more.
Maps offer the level of realism you look for in materials. The different types
of maps you can use range from the common bitmap, to the flexible procedural
map.
For many map types, the renderer needs instructions telling it where the map
should appear on the geometry. These instructions are called
mapping
