[osg-users] TriangleStrip mesh is not smooth...

[Christian Buchner]

Updating a mesh in real time could be done using some a displacement
mapping in a vertex shader. The height field can be then updated as a
texture.

The base mash would be essentially static and flat, but the z coordinate is
updated on the GPU based on texture input.
