Shader Data Objects

Constant descriptions

Wrap: Values outside the valid range of uv values are to be wrapped. To wrap a shader effect is to replicate the entire effect across the mapped area.
Clamp: Values outside the valid range of uv values are to be clamped. To clamp a shader effect is to replicate the boundaries of the effect across the portion of the mapped area that lies outside the valid range.

Data Format



 
ShaderUVBoundaryEnum                uBounds

ShaderUVBoundaryEnum                vBounds

uBounds: The value in this field determines whether values in the u parametric direction that lie outside the valid range are wrapped or clamped by the parent shader.
vBounds: The value in this field determines whether values in the v parametric direction that lie outside the valid range are wrapped or clamped by the parent shader.

Data Size

Description

A shader data object is a boundary-handling method specifier that determines how a parent shader handles parametric uv values that are outside the valid range (namely, 0 to 1).

Parent Hierarchy

Data.

Parent Objects

Any shader. A shader data object always has a parent object.

Child Objects

None.
