AGL_ACCELERATED (2)

[vhoffmann]

Hi DJ Tricky S.
I made a mistake I have a G4 with ATY Rage 128 Pro video.
Now when I put AGL_ACCELERATED in the pixel attribut for aglChoosePixelFormat. There is no difference than if I don't use it.
Is there something else to do to use the hardware acceleration?
Are there example that can show the difference between hardware and software acceleration?
Thanks.

I dunno if it helps but here is what I usually use for pixel formats on my Mac OpenGL programs (pre-OSX mind you):



// if I want 32-bit:
GLint pixel_attributes_32bit[]= {
AGL_ACCELERATED,
AGL_RGBA,
AGL_DOUBLEBUFFER,
AGL_DEPTH_SIZE,
32,
AGL_NONE
};
// if I want 16 bit:
GLint pixel_attributes_16bit[]= {
AGL_ACCELERATED,
AGL_RGBA,
AGL_DOUBLEBUFFER,
AGL_DEPTH_SIZE,
16,
AGL_NONE
};
// if I don't care about HW accelleration:
GLint pixel_attributes_any32bit[]= {
AGL_ALL_RENDERERS,
AGL_RGBA,
AGL_DOUBLEBUFFER,
AGL_DEPTH_SIZE,
32,
AGL_NONE
};
GLint pixel_attributes_any16bit[]= {
AGL_ALL_RENDERERS,
AGL_RGBA,
AGL_DOUBLEBUFFER,
AGL_DEPTH_SIZE,
16,
AGL_NONE
};
