Cameras

• camera (cmr)

Camera description

Optional camera description chunks go inside Camera chunks to define attributes of the camera.

• focus distance (fcsDstnc)
• aperture size (aprtr)
• shutter speed (shtr)

Objects

• shared vertex mesh (msh)
• Planar mesh with shared vertices (plnrMsh)
• sphere (sphr)

Vertex properties

• vertex positions (vrtxPstn)
• vertex normals (vrtxNrml)
• vertex uv coordinates (vrtxUV)
• vertex irradiances (vrtxIrrd)
• vertex radiant exitances (vrtxRdEx)

Patches

Patch chunks are used to make up high level surfaces. For example, triangle patches can be used to make a mesh.

• triangle list (trngl)
• quadrilateral list (qdrltrl)
• triangle strip (trnglStr)
• polygon (plygn)
• complex polygon (cmplxPly)
