Hello.
In glBlendFunc, I should guess that alpha value A in color(R,G,B,A) is used for blend factor.
Well, I can’t explain about next case:
<e.g.1>
glBlendFunc(GL_SRC_ALPHA, GL_ONE);
src color : (0, 0, 0, 1.0f)
dst color : (0.7f, 0.5f, 0.5f, 1.0f)
<my explanation for e.g.1>
src blending factor is (1,1,1,1).
dst blending factor is (1,1,1,1).
new destination color is
(10+10.7f, 10+10.5f, 10+10.5f, 11.0f+11.0f) = (0.7f, 0.5f, 0.5f, 2.0f(??))
#new dst color’s alpha value is 2.0f??
Is this above explain all right?
Can alpha value have 2.0f value?
If you have any advice, please point out above explain and I’m glad to hear your advice.
sorry, my immature English.
Thanks.
