hi all...

i have some terrain that i have drawn using triangle strips and now i need to plot 2D contours onto the surface. i have discovered something called marching cubes but it is hard to understand(the very few examples that i have found) and most of them are old and seem to be outdated. is there another way to plot 2D contours? i already have my terrain colormapped, a deep blue to a light blue with light blue representing the highest points of the terrain and the deep blue the lowest points. where do i (should i) go from here? thanks all in advance for your help..
