glBlendColor: set the blend color
Function Definition
void glBlendColor(GLfloat red, GLfloat green, GLfloat blue, GLfloat alpha);
- red, green, blue, alpha
- specify the components of GL_BLEND_COLOR
Description
The GL_BLEND_COLOR may be used to calculate the source and destination blending factors. The color components are clamped to the range [0, 1] before being stored. See glBlendFunc for a complete description of the blending operations. Initially the GL_BLEND_COLOR is set to (0, 0, 0, 0).
Notes
The type of the red, green, blue, and alpha parameters was changed from GLclampf to GLfloat. This change is transparent to user code.
