<p>A schema and style sheets for DIBR data are provided. The schema includes: a BitWrapper node schema used for graphics data compression; and a Depthlmage node schema, which is used for depth image-based model rendering, includes camera information and texture information having a depth information, defines diTexture as an element including SFDepthtextureNode as a model group, wherein the BitWrapper node schema includes: a node element, which contains graphics data including data to be compressed and refers to SFWorldNode as a subelement; a BitWrapperEncodingParameter element; and three attributes having the names type, url, and buffer and the types SFInt32, MFUrl, and SFString, respectively. The schema and style sheets allow an author to easily control the representation and compression of DIBR when authoring 3D contents and to easily generate an input file for an MPEG-4 encoder.</p> |
