The viewport is a non-recursive ray-march the same way as in the minecraft dweet, the only difference is rather than painting with distance, it uses the same voxel addressing to retrieve the current lighting values... this is all rolled into a single loop of course 😉

[Thomas Brierley @tomx0r]

Real-time, ray-marched, 3D global illumination... on a single CPU... in JS... in 320 bytes... Too big for Dwitter, but I'm still pretty happy with the results:

[Thomas Brierley @tomx0r]

The lighting is forward ray-marched, starting with a pseudo random unit vector from a source. Upon intersection, intensity is added to the the closest voxel address on an object. It marches back once to ensure the next ray has full range, gets a new unit vector, and recurses.

@KilledByAPixel Yup runs fine in Chrome, Firefox is slow, not sure why. This game is hard, you made it look so easy 🥲 will see how far I can get

[Thomas Brierley @tomx0r]

@KilledByAPixel Nice, that did it 👍🎮
