Preserving the GLBlendFunc
I need to preserve the current GlBlendFunc so can restore it after I do some work. It seems that this is开发者_开发问答 not one of the attributes that can be saved with GLPushAttrib, is there some other similar method I can use to preserve the state?
glGet
with GL_BLEND_SRC
and GL_BLEND_DST
(and glIsEnabled(GL_BLEND)
, if you're not sure whether it's enabled).
