14 Managing Shader Characteristics
Q3Shader_GetUBoundary
function to get the current boundary-handling method for u values that are outside the range 0 to 1.
TQ3Status Q3Shader_GetUBoundary ( TQ3ShaderObject shader, TQ3ShaderUVBoundary *uBoundary);shader
A shader.uBoundary
On exit, a value that indicates the current method of handling u values that are outside the range 0 to 1. See "Boundary-Handling Methods" on page 14-17 for a description of the values that can be returned.
Q3Shader_GetUBoundary
function returns, in the uBoundary
parameter, the current method used by the shader specified by the shader
parameter of handling u values that are outside the range 0 to 1. If Q3Shader_GetUBoundary
completes successfully, the uBoundary
parameter contains one of these values:
typedef enum TQ3ShaderUVBoundary { kQ3ShaderUVBoundaryWrap, kQ3ShaderUVBoundaryClamp } TQ3ShaderUVBoundary;
