pairingglBlend
pairingglBlend is a concept found in computer graphics, specifically related to OpenGL and its blending capabilities. It refers to the process of combining the color of a source pixel with the color of a destination pixel already present in the frame buffer. This combination is governed by a blending equation that uses specific factors, often referred to as "source factor" and "destination factor," to determine how much of each color contributes to the final output.
The core idea is to control how transparent or opaque objects are rendered when they overlap. For
Commonly used factors include GL_ZERO, GL_ONE, GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_DST_ALPHA, and GL_ONE_MINUS_DST_ALPHA. For example, using GL_SRC_ALPHA as
