Hello,
I’m trying to determine how I can get the
vertices produced by ‘glEvalCoord1f’…
Of course, I already have the control points.
It’s the points that are on the curve
generated which I need.
All help is aappreciated. Thanks!
Jon
I’m using the example from Chap12 (redbook)
as follows:
glMap1f(GL_MAP1_VERTEX_3, 0.0, 1.0, 3, 7, &ctrlpoints[0][0]);
glEnable(GL_MAP1_VERTEX_3);
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(0.5, 0.5, 0.5);
glBegin(GL_LINE_STRIP);
for (i = 0; i <= 30; i++)
{
glEvalCoord1f((GLfloat) i/360.0);
}
glEnd();
