The new alpha blending algorithm (“dual-alpha blending”) is: - C_out⋅A_out = C_bg⋅A_bg⋅O⋅(1 − A_fg⋅O) + C_fg⋅A_fg⋅O + C_out⋅A_out = C_bg⋅A_bg⋅(1 − O) + C_fg⋅A_fg⋅O - A_out = A_bg⋅O⋅(1 − A_fg⋅O) + A_fg⋅O + A_out = A_bg⋅(1 − O) + A_fg⋅O This algorithm works as the normal alpha blending algorithm if the opacity is used instead of alpha, |
