Im working on a system for skeletal animation and each bone’s angle is based on its parent. I have to rotate that bone from the end of the parent joint for that angle to be accurate as illustrated in the first part of this illustration:
What I need to do is the second part of the illustration. This is because my drawing API only supports rotating around the center of the bitmap.
Thanks
Combine the rotation with a translation. Rotate the figure about the center, then move it to where it should be.
