A WebGL Tomb Raider engine written in TypeScript.
If you're interested in open-source Tomb Raider engines, you should probably check out OpenTomb or OpenLara, which are more fully featured.
jsRaider is just my hobby project for tinkering with. The focus of jsRaider is on a PS1 inspired aesthetic but with no visible aliasing. This actually requires a fair amount of care and feeling with regards to texture sampling & filtering.
Clone with git clone --recurse-submodules git@github.com:tommadams/jsraider.git
Compile with tsc -w
