The displace modifier can be used to generate terrain from a heightmap. Is there a way to modify the mesh according to curvatures obtained from the heightmap?

  • $\begingroup$ I don't think this is possible atm (unless you count manually painting geometry with dyntopo), but hopefully will possible automatically be once osd is fulled integrated $\endgroup$ – gandalf3 Jul 4 '14 at 16:55
  • $\begingroup$ @gandalf3 Note that I want to construct the mesh purely from the heightmap. An option "Subdivide mesh from texture" for the displace modifier would be nice. From that video, I would guess that osd will be used for something else. $\endgroup$ – user877329 Jul 4 '14 at 17:43

    $\begingroup$ @user877329 osd supports adaptive subdivision, which I think means it subdivides parts of a mesh which need it while keeping other parts low poly. $\endgroup$ – gandalf3 Jul 4 '14 at 19:07

    $\begingroup$ You could add a Decimate modifier after the Displace. This will reduce geometry on flat areas and leave more geometry at areas of high curvature. $\endgroup$ – MarcClintDion Jul 5 '14 at 3:18
