Date: Sat, 10 Apr 2004 10:05:46 +0200 From: Christian Walther 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
