Here I’m going over what I did in 2021.

Built a Raspberry Pi Cluster #

• Yes it’s all networked and in a PC case.
• Did not really use it for anything yet.

Wrote a ray tracer in C++. #

I bought The Ray Tracer Challenge book.

• I wrote a custom unit testing library and a python script to translate Gherkin to C++ tests.
• Created spheres, cubes, CSGs, OBJ shapes from triangles.
• Matrix multiplication, vectors.
• I optimized matrix multiplication (of two 4x4) to be basically O(1), then I realized I could’ve just cached it.
• Played around with gprof to make it fast as I can.
• Creates a small UI for this.
• Added Lua scripting with LuaJIT.
• I learned a lot from this project, but I feel it can be improved a lot.
  • Use GPU instead using CPU, Rewrite in OpenCL, HIP, Cuda? (It can at the moment use all CPU cores).
• I still did not put this to a git repo, and I should do so.

📝 CSG means Constructive Solid Geometry. Basically allows you to combine primitive shapes such as spheres, to come up with complex shapes by doing set-like operations (intersect, union).

Started working on a game project #

• This is still in progress, and I have not got to this again as I was focusing more on the new programming language.
• It’s immensely harder than I thought to squeeze out heavy processing under few milliseconds.
• SFML is easy to use.

Started working on a new programming language #

• Goal here is to create a language with Python like syntax that complies to C99. Statically typed and manual memory managed.
• Strings will be special as the language will copy and free strings it will behave like any other value type like int to the user.

📝 Will be using SDS library for Strings.
