Preserving the GLBlendFunc

I need to preserve the current GlBlendFunc so can restore it after I do some work. It seems that this is not one of the attributes that can be saved with GLPushAttrib, is there some other similar method I can use to preserve the state?

Solution

  • glGet with GL_BLEND_SRC and GL_BLEND_DST (and glIsEnabled(GL_BLEND), if you're not sure whether it's enabled).
