Having looked at the example in the Red Book, I coded up my Bezier
surface display application. As I have multiple Bezier surfaces to display
how do I go about doing that ?
I can understand the need to call glEvalCoord2f for every call to
display() but how does one handle glMap2f and glMapGrid2f for multiple
Bezier surfaces ? Do we iterate through our list of Bezier surfaces and call
glMap* for every surface during every call to display() ? Is there a more
efficient approach ?
Is there any example ?
