Signed Distance Field rendering, based off of http://www.valvesoftware.com/publications/2007/SIGGRAPH2007_AlphaTestedMagnification.pdf
The following images are rendered using a 1024x1024 signed distance field generated from a 4096x4096 source image (93.75% reduction in texture memory used, can be reduced further if only the alpha channel is used)
Rendering text using signed distance field technique
Rendering text with an outline
How the texture actually looks
What a 1024x1024 texture would look like without this technique
Generator creates images like this using all available cores, this is the texture used in the above renderings, it was generated from SDF/Generator/test.png (a 4096x4096 image)
