Why is gluTess not working on first call?

I am using the gluTess* functions to draw non-convex polygons. To avoid redoing the tesselation at every step, I store the result in an array and use the vertex array capabilities of OpenGL to draw.[详细]

plotting and coloring data on irregular grid

I have data in the form (x, y, z) where x and y are not on a regular grid. I wish to display a 2D colormap of these data, with intensity (say, grey scale) mapped to the z variable. An obvious solution[详细]
