Features

Geometry

• Triangles a set of triangles
• Polylist a set of polygons with no holes
• Polygons a set of polygons that can contain holes (holes unimplemented, currently an alias for Polylist)
• Lines a set of lines

Source Data

• Vertex
• Normals
• Multiple texture coordinate sets

Materials

• Shader types: phong, lambert, blinn, constant
• Effect attributes: emission, ambient, diffuse, specular, shininess, reflective, reflectivity, transparent, transparency
• Texture support: Can read from local file, zip archives, or a custom auxiliary file handler
• Loads texture images with PIL if available

Lights

• Directional
• Ambient
• Point
• Spot

Cameras

• Perspective

Scenes

• Full scene construction
• Transformations: rotate, scale, translate, matrix, lookat (for cameras)
• Supports iterating through a scene, yielding transformed geometry

Controllers

• Currently experimental (more support coming)
• Morph
• Skin

Additional Features

• Fast triangulation of polygons
• Fast computation of normals
