2. The computer readable medium of claim 1 , wherein the diTexture element in the depthimage node schema defines an SFDepthTextureNode node schema including PointTexture and SimpleTexture as elements.
2. The computer readable medium of claim 1 , wherein the diTexture element in the depthimage node schema defines an SFDepthTextureNode node schema including PointTexture and SimpleTexture as elements. 4. The computer readable medium of claim 2 , wherein a node schema for the PointTexture defines at least one of width, height, depthNbBits, depth, and color as an attribute name, and attribute types defined in the node schema include SFInt32, SFInt32, SFInt32, MFInt32, and MFColor.
