zloedi / roguelike_FOV.c
Last active Jan 30, 2019
Efficient roguelike grid FOV / shadowcasting in a single C function inspired by
View roguelike_FOV.c
What this function does:
Rasterizes a single Field Of View octant on a grid, similar to the way
FOV / shadowcasting is implemented in some roguelikes.
Uses rays to define visible volumes instead of tracing lines from origin to pixels.
Minimal processing per pixel (each pixel is hit only once most of the time).
Clips to bitmap
Steps on pixel centers
Optional attenuation
Optional circle clip
You can’t perform that action at this time.
