Separable lighting |
So I want to talk briefly about lighting.
The classic method of illumination in games involved adding up all the lighting affecting a point, which gives you an RGB value. For static lighting, you either add this up per-vertex, or maybe per-pixel in a lightmap, and store it out somewhere. The trouble with this kind of approach is that the lighting value is a fixed color, which prevents you from doing things like realtime time-of-day stuff, or flickering lights, or dynamic shadowing, or whatever.

Welding vertices |
To summarise the problem – welding vertices means you want to find all pairs of vertices with N distance of each other, and join them into one. There’s many uses for this kind of stuff.
The trouble is you often see it implemented using a O(n^2) algorithm, like such –

Waxeye |
Waxeye is a simple scannerless parser generator.
I’m uploading some Win32 binaries for it, as it was a bit annoying to have to build it from source. Hopefully someone else may find this helpful.

Yes, we have threading! |
At long last, with many thanks to the wonderful efforts of Dan Engelbrecht, we finally have support for profiling programs with more than one thread.
