Hello,

I was wondering if anyone has seen Pascal code around for these two tasks

1> generate level curves from an array of 3D points

2> Generate a 3D surface from an array of 3D points. Here so far my best idea is using the marching cubes algorithm. I'd prefer only triangles, since those fit better to OpenGL.

thanks,

Pretty good! Unfortunatelly in my case the input is much more complex. Here it seams to be a grid with heights given as input. I have an array of 3D points. Maybe I should first generate a grid of heights and then try the code here.

And I got something wrong in the other question. The english terminology is "countour line", in portuguese it is "Curva de nivel", and my direct translation didn't work out very well =)

i can translate for you if you need
