How to use quaternion in blender. When you select the quaternion mode in blender the xyzw components describe a normalized quaternion. When rotating interactively in quaternion mode the so called norm length of the quaternion will remain constant. Before explaining how these rotations work we ll need to define a few terms first. My temporary solution current looks like. 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.
When exporting i need the rotation as quaternion. Ok thanks for the info. Use the info window while doing what you want to do by hand. 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. 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.
I tried testing it out briefly using the xyz eulers and didn t notice any issues or problems. Math can be performed on quaternion classes. It will show you most of the python you need to do. Quaternions are 3d rotations performed by the multiplication of quaternions. By definition the norm of a quaternion equals 1 0 that s a normalized quaternion.
Test numeric values within epsilon. 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. Numbers make up everything we do on computers including blender. 1 in computers everything is represented by numbers. I am writing a blender exporter for my scene format.
The cpp project comes from the basic tracking samples that outputs text in the console for the palm.
