I am a new user of OpenCASCADE. I am trying to generate a 3D surface to model the topography of an area.
I am using the "surfapp" within the test harness DRAW to generate the surface in the following:
surfapp s 186 120 \
x1 y1 z1 \
x2 y2 z2 \
xN yN zN
The (x,y,z) triplets contain the elevation data at 22,320 locations. The "surfapp" command finished without giving any error information. But it hangs when I try to view the generated surface using "view 0 AXON".
My question is
1. is there a better way to generate terrain geometry using opencascade?
2. how should I display the generated terrain geometry?
Thanks in advance for any help on this problem.
