Hello,
I have a few questions about the new SDF render:
1. From the comments in ftsdf.c, "The basic idea of generating the SDF is taken from Viktor Chlumsky's research paper", i expect this is a multi-channel SDF generator, but "For @FT_RENDER_MODE_SDF the output bitmap buffer contains normalized distances that are packed into unsigned 8-bit values" imply this is a regular SDF. Which one is correct?
2. Are there any tutorials about how to use the SDF render? or some reference OpenGL shaders?
Thanks in advance,
zhuyie
