Wow, this implementation outdoes what I came up with, great work! I'll rename my function to injection with the new info you provided.

Ok, so with the constraint of r never exceeding 262144 the limits on the coordinates are (-17, -17, -17) to (18,18,18) for 3d and (-27, -27) to (28, 28) for 2d. I comapred every mapping in the 2d area coordinates and the 3d volume coordinates and found no collisions. This function is now truly bijec...

I started adding constraints on the coordinates, I should have this actually working in a day or two.
*edit* I added a lazy constraint on the coordinates and I calculated the maximum absolute value of the magic number.

Thanks Zorg, this clarifies even further. I guess the stackexchange post I found was wrong about the formula being bijective. Math isn't exactly my strong point.

Uncommenting line 216 will attach the black screen shader to the background entity.
Commenting out line 214 Will remove the background from the world, so there isn't a duplicate image when adding the code I posted to main.lua

I'm having a problem with the Moonshine modules. Attempting to draw the shader causes the screen to go black instead of correctly applying the shader. I have a few draw wrapper functions in the Kernel module, drawShader, drawQuadShader, and drawTextShader. These wrapper functions call Moonshine. The...

For memory, on windows at least you can use perfmon to record memory usage. https://success.scribesoft.com/s/articl ... mory-Usage
For getting the amount of texture memory on the video card you can call love.graphics.getStats().

Thanks for posting info on the magic number affecting collision chances. I didn't consider it too important to mention that it is only for mapping integers since I wrote it mainly to work with a chunking system. Also thanks for pointing out that I accidentally added a few globals.

I created a small helper function for mapping vectors to whole numbers. https://github.com/IAmSegfault/N3N This is useful for creating a deterministic rng for each chunk in your game world, for example the procedurally generated universe in the 1984 version of Elite. I haven't tested it thoroughly, ...

Thanks, this is the correct answer.
