Atom Posted April 23, 2015 Share Posted April 23, 2015 Hi All, When I fetch the Matrix4 from a Houdini object I notice the numbers for rotation don't match what is displayed in the Transform panel. Does this mean Houdini is stores rotate value as radians for the Matrix? Quote Link to comment Share on other sites More sharing options...
pezetko Posted April 23, 2015 Share Posted April 23, 2015 http://www.cs.mtu.edu/~shene/COURSES/cs3621/NOTES/geometry/geo-tran.html So for object that is rotated 45 degrees around X axis you got this (world) transform matrix4: [[1, 0, 0, 0], [0, 0.707107, 0.707107, 0], [0, -0.707107, 0.707107, 0], [0, 0, 0, 1]] Quote Link to comment Share on other sites More sharing options...
