Subject: [SDL] OpenGL Accumulation Buffer on Mac OS X
Is there a reason for not having OpenGL accumulation buffer support in
SDL 1.2.7 (and as far as I have checked also in the current CVS) on Mac OS
X?
Maybe I am doing something wrong, but it seems very easy to add (at least
it works for for me in 10.3.3) - just add
if ( this->gl_config.accum_red_size + this->gl_config.accum_green_size + this->gl_config.accum_blue_size + this->gl_config.accum_alpha_size > 0) {
attr[i++] = NSOpenGLPFAAccumSize;
attr[i++] = this->gl_config.accum_red_size + this->gl_config.accum_green_size + this->gl_config.accum_blue_size + this->gl_config.accum_alpha_size;
}
to QZ_SetupOpenGL() in SDL_QuartzGL.m
