Blending FK and IK in the leg component
I do mention this early in the stream, but just to re-iterate the point: If you watch videos as they come out you might be surprised to find episode 14 going live and no episode 13 up yet.
First: Don’t panic! You can watch this and it won’t be a problem to keep up if you’re up to 12. What we did in 13 is largely theory, which isn’t required for any other episode as it was pretty philosophical, and on the practical front we only fixed a few connections and names in the rig.
By downloading the scene from the resources page you can easily catch up to it, as well as dissect the fixed asst.
The reason it didn’t go up right away after I finished the stream is that it’s a subject I’m particularly fond of and I feel I need to either edit it, or at least release it with an intro and (possibly) an errata. I should be able to get to it during the coming weekend.
If you read/watch these a few days or more late you will have seen 13 up and all will be well.
Getting to the point though: This stream we added FK to the leg and showed how to trivially blend between FK and IK as well as discussed how we could cut down and compress the graph even further in the near future.
There isn’t really much in the way of required knowledge, but if you haven’t followed, or don’t remember, the theory from the Pilot Season episodes the Matrix Maths one is worth a watch as we do make use of matrix mult again.
