This is a simple voxel engine made with Odin and OpenGL.
I want to turn this into a simple framework for myself so I can prototype different game ideas with it.

At the initialization stage it creates 49 chunks. Each with 32x64x32 blocks. That's around 3.2 million blocks.
The chunk generator creates caves and simple mountains using a mix of 2d and 3d OpenSimplex noise.
The chunk generator also takes a seed as input meaning that you can create new worlds just by changing a value.

 //params : current chunk, seed
 create_chunk_data(&chunks[i], 5)

Each chunk has its own mesh and faces that the player can't see are culled.
Currently there's no dynamic chunkloading and you can't edit the terrain but I want to add those features later on.

The memory usage is around 64MB
I tested this on a Intel Core i5-7200U and it ran around 90 - 120 fps.
I still want to optimize this further so it can run on even lower end devices.

I started this project to learn the Odin programming language and OpenGL.
I really enjoyed working with Odin for this project as it a simple and very productive language. Most of the features were made within a week.
A few disadvantages of using Odin is that it lacks a lot of documentation due to it being a rather new language.
I do recommend Odin as it has a lot of quality of life features over C. It also has a very readable syntax.

To run this program copy the repo and run the following with the Odin compiler in a terminal:

 odin run src/.
