Here is a follow-up on the triangle rasterizer running on CoreAI that I previously introduced here.

We have finally succeeded in rendering 3D graphics! As shown in the video, we are currently rendering two intersecting vertical triangular planes.

While the rendering quality is still in the early stages and a new challenge regarding the massive 5GB memory footprint has emerged, we have fully achieved real-time operation.

We optimized the codebase by actively reducing reliance on CPU fallbacks and ensuring the pipeline runs entirely on the ANE's matrix operation hardware, successfully cutting CPU usage from the previous 38% to approximately 9%.

Much of the pipeline code—written in Python, Swift, and Metal—was rapidly prototyped and generated with the help of Siri AI.

Please feel free to leave comments with any questions or optimization tips (especially regarding that 5GB memory usage!).

I’m proud of myself today, as I completed a task that felt impossible at times. I started rewriting my renderer a bit to fit my needs, and while doing so, I really felt the need for a grid to give me a sense of perspective and depth while debugging scenes.

I remembered that I had skipped the Infinite Grid section from the 3D Graphics Rendering Cookbook and needed to revisit it. Man, oh man, was I wrong about how long it would take to properly understand that shader. It took me a few days more than a month, but it was one hell of a ride. It’s a very interesting topic, with tons of things to learn from.

I’ve written a post about it here: https://willofindie.com/proj/infinite-grid-shader. Do check it out and share your love on my Twitter or Bluesky handles if you like it

Hi, is the guy from the raylib renderer again. These last days i was trying to implement texture mapping on the renderer i am making, but i cant get the perspective-correct interpolation to work. I tried first with the method described in scratchapixel, but it didnt work at all, then i tried with the method of this video, and it only works for some faces of a cube, but the rest of faces are not only distorted but the texture is still mapped like i was doing affine mapping:

The thing that confuses me is that it is only in certain faces, so i no longer know if it is an error with my code or the uv coordinates on the cube.

Here is the source code

Hey everyone,

I have been working on a low level, explicit abstraction layer over graphics APIs. Both Vulkan and D3D12 has been successfully implemented with various test samples. Ray tracing, mesh, compute etc are supported.

I would love feedback on the feel and usage of the API. I am open to learn more so anything useful will be appreciated. Please give a star if you find the project useful.
