- add != operator
 2014-12-31 17:07:19 +01:00
Joni Vähämäki 2c1ae44b5c GRIM: Fix matrix to quaternion conversion. Fixes #1132 2014-12-25 23:12:26 +02:00
Christian Krause 0fe9168944 MATH: Don't normalize a (0, 0, 0, 0) quat 
- this fixes the issue of the vanished boats in EMI's lava puzzle
- without the patch, the division by 0.0f causes the quat's values
  to be NAN
- the floating point NAN value is ignored by OpenGL, so the vertices
  are not drawn at all

Joni Vähämäki b5cdd1240f EMI: Only draw models for actors inside the view frustum. 
This adds math classes for doing frustum culling in software. These could be used for optimizing performance in many other places as well. For example, if an actor is outside the view frustum, it may not be necessary to do expensive keyframe animation and vertex skinning calculations for that actor.
