I am using glMap2f method as..
glMap2f(GL_MAP2_VERTEX_3, 0.0f,1.0f,3,nUOrder,0.0f,1.0f,3*nUOrder,nVOrder,fM eshCtls);
but it gives error GL_INVALID_VALUE..
here values of both nUOrder and nVOrder are 50.
this method gives Result=30..
I read somewhere on internet that i want to write my own Evaluator but didn't get any example..
So anybody can tell mi how to write own Evaluator..?
or how to solve this problem...?
