[Blend2cs-user] blend2cs coordinates system
Wed Aug 18 11:01:34 CEST 2004
I had a talk with Jorrit and here are the convention in blender and CS
Blender: X->1 is right, Y->1 is pointing to the front of me, Z->1 is up
CrystalSpace: X->1 is right, Y->1 is up, Z->1 is pointing to me.
So, if I am not wrong, the conversion is :
crystalspace.x = blender.x;
crystalspace.y = blender.z;
crystalspace.z = blender.y * -1;
