14 Q3Shader_SetVBoundary

You can use the Q3Shader_SetVBoundary function to set the current boundary-handling mode for v values that are outside the range 0 to 1.

TQ3Status Q3Shader_SetVBoundary (
TQ3ShaderObject shader, 
TQ3ShaderUVBoundary vBoundary);
shader A shader.
vBoundary A value that indicates the desired method of handling v values that are outside the range 0 to 1. See "Boundary-Handling Methods" on page 14-17 for a description of the values that you can pass in this parameter.

DESCRIPTION


The Q3Shader_SetVBoundary function sets the boundary-handling method for v values to be used by the shader specified by the shader parameter to the method specified by the vBoundary parameter.
