glBlendBarrier — specifies a boundary between advanced blending passes
void glBlendBarrier(
|
void); |
glBlendBarrier specifies a boundary between passes when using advanced blend equations.
Any command that causes the value of a sample to be modified using the
framebuffer is considered to touch the sample, including clears, blended
or unblended primitives, and BlitFramebuffer copies. Defined results are guaranteed only if each sample
is touched no more than once in any single rendering pass.
