Hi.. It's the second time I post for my problem, I'll try to be more
specific.

I have to draw a bezier curve with control points entered with the
mouse. I have an array of those points. They are xyz coords. This is
working fine. It's when I want to compute the the bezier that it does
not work. Here is how I'm doing it:

    glClear(GL_COLOR_BUFFER_BIT);
    glPointSize(3.0f);

    glMap1f(GL_MAP1_VERTEX_3, 0.0f, 100.0f, 3, ptsCnt,
&ctrlPoints[0][0]);
    glEnable(GL_MAP1_VERTEX_3);
    glMapGrid1d(100, 0.0, 100.0);
    glEvalMesh1(GL_LINE, 0, 100);

    glBegin(GL_POINTS);
        for (int i=0; i<ptsCnt; i++)
        {
            glVertex2fv(ctrlPoints[i]);
        }
    glEnd();

    glBegin(GL_LINE_STRIP);
        for (int i=0; i<ptsCnt; i++)
        {
            glVertex2fv(ctrlPoints[i]);
        }
    glEnd();

    glFlush();

ctrlPoints is my array of coords and ptsCnt the number of points. Is
there something missing ?

Isn't EvalMesh supposed to return Vertex3 coords that would paint when
glFlush is called ?

Thanks in advance.
