I was looking for a way to display mouse-over context information in a 3D scene, and the solution I came up with is to encode the ID of each object into colors, and render that to an off-screen framebuffer. Then, I can simply look up the pixel at the current cursor coordinates and get the ID!

It feels like a cheeky hack, but honestly I can't think of any other practical way for this - does anyone know how games and such do this?

I added some simple lighting: shading and shadows from a directional light, and it looks a lot better now.

Will get to more complicated lighting after I tackle voxel chunks.

Simulating a Planet on the GPU: Part 1 (2022)

I finally made voxels render in a 3D perspective on my graphics programming journey! Here's what I did:

- I implemented ray tracing using DDA algorithm for voxel rendering.
- Also learned transform matrices and applied an inverse view matrix for camera movement. (video)

This was really fun, but hard to make, however I'm happy that through all that, I finally got something appealing to the eye.  

Questions are welcome!

This is the only copilot I need. You and I are not the same... 😎

(joking aside I'm glad to have found a physical copy of this absolute bible of a book at a 'reasonable' price after giving mine away many years ago. This completes my black book collection together with @fabinou 's books).
