Appearance Node

The appearance node defines the look of the geometry. This node can only be defined inside a Shape node.

The fields included in this node are: material, texture, and textureTransform. All fields are optional but at least one field should be specified.

The material field contains a Material node. This node specifies the color of the associated geometry, see the Shape node, and how the geometry reflects light. Note that if this field is NULL or unspecified then all lights defined in the world are ignored when rendering the associated geometry.

The texture field contains one of the texture nodes available: ImageTexture, MovieTexture, or PixelTexture. If this field is absent or unspecified no textures are applied to the associated geometry. 

The textureTransform field contains a TextureTransform node. This node specifies how the texture is applied to the geometry. 

Syntax: 

Appearance { 
material NULL 
texture NULL 
textureTransform NULL
