The relevant section of the Blender manual Wiki is currently empty of content, so I ask my question here. I can find no information about how to create different shapes (ranges) of Degrees-of-Freedom (DoF) for joints. I have a humanoid character and that should have human-like limits.
Using the right shoulder as an example, the theoretical DoF should be a sphere around the right shoulder joint. Given the theoretical DoF of a sphere, the volume wherein the upper arm would intersect the body should be subtracted to produce the actual DoF of the right shoulder. This would give a DoF-sphere with a large “hole” in one side. This seems impossible with the current DoF controls (sliders).
What is the problem? I am looking to find more information about defining the DoF for a joint. Perhaps the DoF-shape I’ve talked about is impossible at this point with Blender. Some practical examples would be priceless as, like they say, a picture is worth a thousand words.
