I’m currently coding a class to keep track of gl-states to avoid redundant changes and came across the following from a reference for glEnable:
The initial value for each capability with the exception of GL_DITHER is GL_FALSE.
The initial value for GL_DITHER is GL_TRUE.
This is quoted from http://tc1.chemie.uni-bielefeld.de/doc/OpenGL/hp/Reference/glEnable.html , the documentation for HP’s OpenGL implementation.
What I’m wondering is; is the initial state something that is consistent between vendors?
Eg. does ATIs’ drivers set every state as NVidia sets theirs?
I’m just looking to avoid coding a routine to sync every available state at startup, as you might have guessed.
Thanks for any advice, on either this or state-management in general!
From 3DLabs spec.:
The initial value for each capability with the exceptions of GL_DITHER and GL_MULTISAMPLE_EXT is GL_FALSE. The initial value for GL_DITHER and for GL_MULTISAMPLE_EXT is GL_TRUE.
I suppose it’s safe to assume that initial values are the same across vendors.
