21、in ISO/IEC 14496-16 has the depth information and the color information. PointTexture represents an object with an array of pixels viewed from a single camera location. Each PointTexture pixel is represented by its color, depth (the distance from the pixel to the camera), and a few other properties

22、assisting PointTexture rendering. There can be multiple pixels along each line of sight, and thus a PointTexture usually consists of multiple layers. A PointTexture typically contains a large amount of data: a realistic image requires a higher sampling density and a huge amount of data. Therefore, t

23、he compression of PointTexture images should be done efficiently. The PointTexture compression is a tool to compress the PointTexture node efficiently. 8.5.8.1 Conformance Points 8.5.8.1.1 Covered functionalities The conformance points for PointTexture compression cover lossless compression and loss

24、y compression. These functionalities relate to the compressed representation of PointTexture node carried by BitWrapper node as described in ISO/IEC 14496-11. As for carriage of compressed representation of PointTexture node using BitWrapper node, it can be carried either in a separate stream or wit

25、hin the scene stream (BIFS stream). Therefore, PointTexture compression shall also be tested together with this node. The following subclauses specify the normative tests for verifying the conformance of PointTexture compressed bitstreams and PointTexture decoder. Those normative tests make use of t
