Macha Posted December 20, 2011 Share Posted December 20, 2011 (edited) Out of curiosity and interest, does anybody know a code or an algorithm or an explanation of what the vector4 quaternion(float angle, vector axis) does internally? I'm trying to replicate it. Edited December 20, 2011 by Macha Quote Link to comment Share on other sites More sharing options...
Erik_JE Posted December 20, 2011 Share Posted December 20, 2011 (edited) I like this page: http://www.euclideanspace.com/maths/geometry/rotations/conversions/angleToQuaternion/index.htm I am not gonna try to explain it with my own words. Thinking Quaternions makes my brain boil after a while. EDIT: Posted wrong url a couple of times but this should be the correct one describing axis angle to quaternion.
