A* pathfinding applied to roto poly edges As I mentioned in my earlier posts about anti-aliasing, I'm currently working on a Nuke rotoscoping plugin. The default Nuke rotoscoping plugin is really an artist's drawing tool. You can define polys or paint on the image to create a roto matte. If you need a more precise edge, you'd
City Generation Procedural Architecture I thought it'd be interesting to go back and review a bit of work I did for fun a few years ago. I'd been reading Shamus Young's excellent series of articles about building a procedural city. It fascinated me and I set out to make my own, but with a
Full body tracking in a virtual world My Perception Neuron mocap system finally arrived last week. I ordered it after Siggraph 2014 last year. It's been a bit delayed, and it looks like the final price has increased dramatically since its Kickstarter (what I paid $340 for looks like it now costs over $1200 on their web
Performance Analysis and Optimization of A-Buffer Antialiasing It's performance analysis and optimization time! Truthfully, this is one of my favorite parts of any project. Most of the time it ends up being a very rewarding experience. Although ironically it's rewarding inversely to how clever you were when you originally wrote your code. If the code is already
Anti-aliasing Polygon Edges for Scanline Rendering Anti-aliasing is something many of us take for granted these days. Certainly in the realtime world there are a number of well-known techniques using clever manipulation of graphics hardware (MSAA, FXAA, TXAA) each with variations in quality (2x, 4x, 8x, 16x) with associated higher GPU processing costs. But outside of
City Generation Procedural City Generation I was originally inspired to look into procedural city generation after reading Shamus Young’s article about creating a simple night-time procedural city using no geometry or texture assets (only code). I made my own version, but I wasn’t happy with a simple grid layout for the city and
