Open blender delete the default cube add a monkey and switch the rotation mode to quaternion i know not much of a challenge yet for most of you but wait fill in the w x y z fields so that suzanne rotates 180 around the axis that goes through 0 0 0 and 3 4 5.

How to use quaternion in blender. In blender the bones are configured to use quaternion rotation so ithought it was just a matter of finding the correct axis but it seems the values arent in the same range or i didnt find the good axis combination yet. Comparison operators can be done. It will show you most of the python you need to do. My temporary solution current looks like. When exporting i need the rotation as quaternion.

When you select the quaternion mode in blender the xyzw components describe a normalized quaternion. Ok thanks for the info. Numbers make up everything we do on computers including blender. By definition the norm of a quaternion equals 1 0 that s a normalized quaternion. When rotating interactively in quaternion mode the so called norm length of the quaternion will remain constant.

Test numeric values within epsilon. The problem is in blender you cannot switch back to quaternions once you started using eulers for the animations unless you want to re do the animations. Quaternions are 3d rotations performed by the multiplication of quaternions. Before explaining how these rotations work we ll need to define a few terms first. That should get you started.

The cpp project comes from the basic tracking samples that outputs text in the console for the palm. This object gives access to quaternions in blender. Math can be performed on quaternion classes. The easiest way i found is to use the rotation quaternion but this member only guarantees to store the rotation when the rotation mode is set to quaternion. I am writing a blender exporter for my scene format.

I already use the info window when figuring out how to script things with blender but how would this help me extrude bones that default to something other than a quaternion rotation mode.
