Table 6.292—DRM_Texture_Coordinate_Table

Property

Description

Superclass

·         <DRM Hierarchical Table>

Class

·         <DRM Texture Coordinate Table>

Subclass

·         none

Definition

A <DRM Texture Coordinate Table> is a part of a hierarchical collection of <DRM Texture Coordinate> objects that can be referenced by index. It is a specialization of the <DRM Hierarchical Table> class and is used in conjunction with the texture_coordinate_index field of the <DRM Vertex With Component Indices> class. See the <DRM Hierarchical Table> and <DRM Vertex With Component Indices>.

Example(s)

·         Consider a <DRM Union Of Primitive Geometry> containing multiple quadrilateral <DRM Polygon>s that use the same <DRM Texture Coordinate>s for their <DRM Vertex With Component Indices>. Each <DRM Polygon> has one <DRM Image Mapping Function> for the OTW presentation domain.

·         Consider a <DRM Union Of Primitive Geometry> containing multiple triangular <DRM Polygon>s that use the same <DRM Texture Coordinate> for their <DRM Vertex With Component Indices>. Each <DRM Polygon> has one <DRM Image Mapping Function> for the OTW presentation domain and another for the thermal domain.

Each <DRM Vertex With Component Indices> references a <DRM Texture Coordinate Set> within the <DRM Texture Coordinate Table> of the <DRM Union Of Primitive Geometry> . Each <DRM Texture Coordinate Set> contains two <DRM Texture Coordinate>s, one for use with OTW and the other for use with thermal.
