Property

Description

Superclass

·         <DRM Control Link>

Class

·         <DRM Texture Coordinate Control Link>

Subclass

·          

Definition

This is the specialized <DRM Control Link> used to provide the connection between an ordered aggregation of <DRM Expression>s and the target fields of a <DRM Texture Coordinate>.

The s_expression_index field is one-based index into the ordered aggregation of <DRM Expression>s, and is used to select the specific <DRM Expression> that controls the value of the s field of <DRM Texture Coordinate>.

The t_expression_index field is one-based index into the ordered aggregation of <DRM Expression>s, and is used to select the specific <DRM Expression> that controls the value of the t field of <DRM Texture Coordinate>.

Example(s)

·         A <DRM Control Link> with a literal expression that specifies the values of “s” and “t” to 0,5 and 0,6 respectively.

Notes

1 A text description of what the <DRM Control Link> is for.

2 Index of the expression whose value controls the s field of the affected <DRM Texture Coordinate>. If zero, the s field is not controlled.

3 Index of the expression whose value controls the t field of the affected <DRM Texture Coordinate>. If zero, the t field is not controlled.
