hello,

what would be the best way to draw a heightfield with OpenGl?
normally you have the data in a two-dimensional array.

i tried it with GL_QUADS and GL_TRIANGLE_STRIPS but the outcome is a little strange as you can see in this screenshot:

the problem is that there is a certain orientation of the polygons which shouldnt be there.

thanks!

It looks to me like your tesselation is not fine enough. Also, when using quads, make sure they're planar.

Looks to me like the field function ...

Is not dynamic enough over that range and also like the other respondent said ... not enough resolution.

no
meanwhile i tried different approches.
now im erndering it linewise with single triangels. this works fine and i get a smooth heightfield.

thanks anyways.
