In my last post, I presented all the primitive shapes I have at my disposal for my C++ #raytracer.
I now used them to create the first object. Here I show them with and without material/textures

I finished implementing a series of new geometric shapes for my #raytracing project.
These are gonna be the building blocks for more interesting objects and scenes coming soon.

For no reason whatsover, I can now play the videos I generate with my #raytracing & #rendering code in the terminal.

Here’s a comparison between regular path tracing and next event estimation (NEE) 🎨
Both methods converge to the same final image — but NEE gets there much faster ⏱️
Here we use 10 times more samples for path tracing, yet the image still looks worse than with NEE.

🌍☀️ More experiments with my C++ #raytracer & #renderer.
Spheres now support color textures. A solar system scene felt like the perfect demo. (Nothing to scale.)
It might not be the most complex scene for a renderer, but it's great for testing textures and motion.

✨ Rotating Object Render
⚙️ Method: Ray Tracing (written in C++)
🎯 Samples per pixel: 10
⏱️ Render time: 2.5 minutes (on 8 cores)
It will probably look much better with path tracing.

I’ve built four different renderers for my ray tracer:
🎨 Simple (base color)
💡 Deterministic (direct light, reflection, refraction)
🔦 Ray tracing
🌌 Path tracing
Each handles light in a progressively more realistic way. And I finally (!) get consistent results among all four. Check it out!

I'm currently trying to improve my ray tracer to be more physically accurate, learning a lot about Physically Based Rendering (PBR).
Oh boy, stuff goes wrong. At least I get some funky images.

For a while now, I have thought about how to model the light ray interaction with surfaces for my ray tracing project.
I finally got around to re-write my code to simulate 3 fundamental types of interactions (+variants and mixtures):
1. Diffuse scatterings
2. Reflections
3. Refractions

A couple of weeks ago, I started to implement a ray tracer as a fun coding project inspired by a Coding Adventures video on youtube.
My ambition is to start from scratch using C++ and see how far I can push it and how long the project is fun and motivating.

OK, this is wild.
In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.
It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.
What the HELL?

Today, I started reading “A philosophy of software design” by John Ousterhout.
So far, it has been really great at putting words on how I somehow feel about certain ways of developing software.
I might share some quotes from the book later.
Let me know if you can recommend similar books. 📚 💻
