I have some issues with alpha blending using OpenGL and the X50v.
Apparently OpenGL|ES supports
glEnable(GL_ALPHA_TEST);
but does not support glAlphaFunc();
As workaround i am using alpha blending via
glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA);
However this is quite slow, since in contrary to GL_ALPHA_TEST it really blends with the color buffer.
Did anyone successfully used GL_ALPHA_TEST or has any ideas? I am using a 5:5:5:1 Texture format.
