This is a voxel rendering engine I've made using C, GLFW, and OpenGL. It loads and unloads chunks as you traverse the world. Chunks are meshed only when loaded or a neighboring chunk is updated (currently only happens if neighboring chunk loads). Chunk meshing is multi-threaded and culls occluded faces - that is, if a block face is next to another block, it will not be added to the mesh.
I've used frustum culling to improve rendering performance. The shaders are relatively simple - they have support for ambient, diffused, and specular lighting. Much of the OpenGL is based off of LearnOpenGL.
To build, just run make. There are dependencies related to OpenGL, GLFW, GLUT, CGLM. I've tested on Ubuntu Linux; I know it currently doesn't work on MacOS (I've tried simply running with make as is, but MacOS does something weird with OpenGL).
This project also includes a Python script to convert .png files into .c and .h files - I use these to create the texture arrays I use in the project as an alternative to loading the images at runtime. For this project, it's used to convert a texture atlas.
