K.jpg's Idea Dump

Game dev, procedural generation, and general coding ideas I come up with and want to make sure others can consider as well. I try to cover a lot of the details / use cases that come to mind, but it would be difficult to cover them all. Not all of these ideas are fully thought through, but they might still be pretty close to usable implementation descriptions. I'll try to update this whenever I think of something to add to it. If you use one of these ideas directly, and you got it here first, credit is appreciated but certainly not required! Credit is whatever, just please stop adding to the development and creativity obstacle minefield that is the sea of software patents.

Noise Generation

Union of reciprocal lattices

• Generate procedural noise, or perform another function on a particular lattice in N-dimensions, by constructing the lattice as a union of copies of its reciprocal lattice.
• Look at the points that each reciprocal lattice misses on the original lattice. Keep p

const int CHUNK_SIZE = 32;

// These variables store the location of the chunk in the world, e.g. (0,0,0), (32,0,0), (64,0,0)

 * Controls:
 *  - rotate object by dragging with the left mouse button
 *  - move cross-section plane back and forth by dragging up/down with the right

How I reversed the assets from Proletariat's Spellbreak.

Proof:

(I have tons more icons in a OneDrive, just ask Vague Density. I only wanted 3 images to prove myself.)
