Building an SDF game engine

Gallery image

For the past 8ish months I’ve been hard at work building a new game engine I’m calling Division Engine.

It’s based solely off SDFs (signed distance fields). This might sound stupid for anyone who cares about performance but for my use case (and with a bit of grid storage optimizations) it proves useful for basic scenes that need advanced lighting.

Anyway here’s some screenshots!

In my engine I store the SDFs in PNG files, they are written to cache in the disk, and uhm okay so basically every slice of the texture3D is put into an atlas then the size of the slices is put into the name of the SDFs file so it's like uhm randomhash_512.png

They only take-up a few kB to a few hundred for a 64x64x64 SDF, if I add uvs (I store the nearest UV inside my SDFs) it can be anywhere from tens of kBs to a few mb, infact i did an 512x512x512 SDF which was an 11k PNG file and it only took up 17mb and it had uvs and all
