Hi,

My final goal is the creation of a full 3D volume mesh consisting of

an extruded rough surface (heightmap). Two of the sides are supposed to be periodic.

To  start with the surface triangulation  I was wondering if there is an easy way to get a 3D surface triangulation from a simple 2D heightmap instead of the 3D gray scale image.

Alternatively i was thinking of turning the heightmap field into a implicit

function.
Another question is how i can control the mesh vertices on the boundary of the surface, so that i have the same discretization at the

two edges of the periodic direction.

In this way i could copy one of the periodic face triangulation over

(translation) to the other side.

Any suggestions comments are welcome.

Thanks a lot in advance
