Mathematics Researcher. Main interests:


  • physics based animation (deformable objects, kinematics)
  • mathematics of CG applications (simulation, games, etc.)
  • shader programming
  • discrete differential geometry (manifold properties)
  • robotics

While you're here, please stop saying these two things

  • quaternions avoid gimbal lock
  • premature optimization

why?

  • gimbal lock is related to a mechanism, quaternions are just an algebraic/geometric description of an angle-axis rotation. So they do not avoid it since the mechanism itself cannot.
  • if it's an optimization, if it's common sense, just implement it! Better do it now, than to look for it desperately later.

Figures, the community for this engine is less and less active :(.

A side note: are the Ogre forums still up and running/active? You should post the question there as well.

comment Colision detection of disc (Maximum Material Condition aka “Flatness”)
+1 for @Paraknight . Besides PCA, if the OP is looking for a robust algorithm for fitting planar faces to a point cloud, RANSAC may come in handy -> en.wikipedia.org/wiki/RANSAC
