It was an honor participating as a BAFTA juror again this year with such a talented group of people! Thank you Katherine Bidwell for being an awesome chair and to all the other jurors!

Congratulations to everyone involved in bringing the event to life, all the nominees, and the winners!

Today we'll look at the FABRIK algorithm. It's a really nice and easy to understand algorithm, easy to implement and can have a lot of uses
Here I'm showing it in a simple form

Here's the sketch

Here's a version of solving inverse kinematics using CCD (Cylic Coordinate Descent). The prevoius methods were analytical methods, this one is iterative, and starts moving into solving for an N number of bones.

The p5js sketch:

In this version, we'll solve the IK using the intersection of two circles!

And the previous two sketches for the other two methods.

I've also tweaked the other sketch using the law of cosines to add some visualizers

Here's another sketch of how you can solve a two bone IK by solving for the opposite side length

And the node network

Continuing some tests I did when Maya 2024 was released with the new math nodes, here was a simple two bone IK solver

And the node network:

When Maya 2024 was released, I made a quick example of how you can implement an anglular pose driver using stereographic projection:

And the node network:

And another version for extracting for the twist > bend (useful for wrists, and ankles)

And the node network:

This is an old one, but figured I'd add it over here to BSky.

This is a quick way to decompose Bend and Twist values from a rotation matrix in Maya:
