Unreal Engine 5.3 launches today! One of the things I worked on (with @RobotBrendan) this release was Learning Agents - an experimental plugin for doing Reinforcement Learning in UE. It's early days & lots to do but check out this tut for a sneak peak!

Something I worked on for Unreal 5.3 is a new experimental "Dead Blending" node - it's a drop-in replacement to the Inertialization node which often produces better blends when the animations are not synced or you have frequent transitions.

I got tired of the shortcomings of most of the .bvh animation file format viewers out there and decided to write my own. BVHView is a simple, hackable .bvh viewer written in #raylib that loads files almost instantly and renders them clearly and cleanly.

Today a blog post in which our character throws some crazy shapes on an alternative method of inertialization sometimes called "dead blending".

I've just uploaded a simple #raylib example application for viewing animation data on a skinned mesh: It has (what I consider) the minimum rendering required to actually evaluate skinned animation: basic lighting, shadow maps, SSAO, and a grid shader.

Animation quality is a difficult subject that I think we've not quite got to grips with yet as a community. My latest blog post shares some of my own thoughts on the subject. My hope is it can kickstart some discussions... or at least new dance moves!

My latest article is about one of my favorite techniques in graphics - Müller's method of Polar Decomposition. It also details some variations, including one which is ~2x faster to compute with more regularly convergence.

How can we compute the weighted average of a set of quaternions? The answer might be a little bit more tricky than you'd expect.
