Per LearnOpenGL (blending), the standard ALPHA blending formula is which?
AC = α × dst + src colour
BC = src multiplied by dst
CC = α times (src + dst)
DC = α × src + (1 − α) × dst
Answer & Solution
Correct answer: D. C = α × src + (1 − α) × dst
LearnOpenGL Blending: glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA) gives C = α·src + (1−α)·dst. Over-operator.
