WebBlitting moves the same types of patterns about the screen, but does so by writing into the same memory as the rest of the display. This means that every time a foreground pattern is placed on the screen, any background pixels underneath it are overwritten, or "damaged". WebMar 17, 2024 · If we use the default blending equation GL_SRC_ALPHA and GL_ONE_MINUS_SRC_ALPHA, it means that if our texture is all (1, 0, 0, 0.3), the resulting RGB will be (1, 0, 0)×0.3 + (0, 0, 0)×0.7 = (0.3, 0, 0) BUT the alpha component will be 0.3×0.3 + 0× (1 - 0.3) = 0.3, so we then have a color of (0.3, 0, 0, 0.09) which is not …
