Dogfood Voxel Engine written in Olive

A voxel engine written in Olive. This is a dogfood project for the language, using it to build something non-trivial that touches structs, references, FFI, math, and real-time rendering.

Olive handles all the game logic. Rendering goes through pygame and ModernGL via import py. Noise generation is a native Olive implementation of OpenSimplex2 (no Python noise libraries needed).

Olive >= 0.6.1 - see installation below

Python 3.x - with dependencies from requirements.txt

Install Olive:

Run:

Structs with mutable and immutable references (&mut, &)

Python interop (import py) for pygame, moderngl, glm, Pillow

Native math - 727-line OpenSimplex2 noise implementation

Const expressions evaluated at compile time

Manual memory layout - packed vertex data (6b pos + 8b voxel + 3b face + 2b AO + 1b flip per uint32 vertex)
