3dfx and PPC 601 Macs

Hello to everybody!

I'm experiencing problems on a PowerMac 7200 under MacOS 8.6 with a
Voodoo3.I have tried running GLQuake, Aleph One, SetupGL, OpenGL DrawSprocket etc. Any code crashes at the first glEnd() when running accelerated. This example is taken from SetupGL. SetupGL runs smoothly with the software renderer.

Has anybody tried this?
Is it a 3dfx problem?
Is OpenGL incompatible with older PPC processors? (601)

regards Roddi


from the SetupGL exmple:

void drawGL(AGLContext aglContext, pstructGLInfo pglInfo)
{
static float f, s, c;
GLboolean fState = GL_FALSE;

f += 0.01;
s = sin(f);
c = cos(f);

glClearColor(0.15f, 0.15f, 0.15f, 1.0f); // Clear color buffer to dark grey
glClear(GL_COLOR_BUFFER_BIT);

glBegin(GL_POLYGON); // Draw a smooth shaded polygon
glColor3d(1.0, 0.0, 0.0);
glVertex3d(s, c, 0.0);
glColor3d(0.0, 1.0, 0.0);
glVertex3d(-c, s, 0.0);
glColor3d(0.0, 0.0, 1.0);
glVertex3d(-s, -c, 0.0);
glColor3d(0.7, 0.7, 0.7);
glVertex3d(c, -s, 0.0);
glEnd(); //<--- Crash here!!!

// Draw frame rate (set color and position first)
.
.
. more code
.

aglSwapBuffers(aglContext); // send swap command
}
