Project mention: I have a few months to prepare for an interview. Is there a project that would get me at least part of the way there for the interview? | reddit.com/r/GraphicsProgramming | 2023-01-23
In terms of a project which would be worthwhile, I think building a software rasterizer from scratch is a useful first step. TinyRenderer is a great place to start. Looking at the high level overview of many graphics subjects, ScratchAPixel is a valuable resource. Theres also just great information in some of the rote graphics programming textbooks (Michael Abrash's Black Book fully available online from Jason Gregory, and this book is really interesting). The "RayTracer in a weekend" series is also (seemingly) very illuminating (no pun intended).

Project mention: CD PROJEKT RED announce The Witcher Remake in Unreal Engine 5 | reddit.com/r/linux_gaming | 2022-10-26
There's also Open3D (O3D) the point cloud library... http://www.open3d.org/

For some reason, that reminded me of this.

Project mention: How to reduce the vertices of this LiDAR scan without ruining the model? | reddit.com/r/blender | 2022-12-18
The best open source way I have found is using MeshLab
-
For the Blender export part, the simplest 3D model format is OBJ. It's a text format that can be read in only ~100 lines of code. You can use Assimp for this. Or you can use something like tinyobjloader: https://github.com/tinyobjloader/tinyobjloader

Project mention: Question, is UEViewer safe to use? I downloaded the master zip folder for UEViewer and scanned the executable inside called umodel.exe and it says that it has a Trojan Virus. Is it safe to launch and use? | reddit.com/r/unrealengine | 2023-01-29
I don't usually trust applications with really awful landing pages, but it is open source and you can try building it yourself: https://github.com/gildor2/UEViewer

Project mention: The Orb: a parametric trackball with BTU mounted ball and keyboard switches for buttons | reddit.com/r/ErgoMechKeyboards | 2022-10-09
curv seems to have cad/slicer integration in mind as a long term goal, using f-rep to generate infill as well as the shape itself.

Have a look at https://github.com/tpaviot/oce/ Not sure if there is a go wrapper for it. There is a python library wrapping opencascade already.

Project mention: TerraForge3D(opensource procedural terrain generation, texturing, shader making tool) major update. (added blender like shader node editor and Linux support) (source in comments) | reddit.com/r/proceduralgeneration | 2022-03-29
-
Project mention: The Bitter Truth: Python 3.11 vs Cython vs C++ Performance for Simulations | reddit.com/r/cpp | 2022-12-30
Most high-performance math libraries perform a lot of vectorization (Eigen, etc) under the hood. And you've got stuff like Klein, Vc (which is reminiscent of std::valarray), etc. Then there's OpenMP's #pragma omp simd (assuming version 4.0 or greater).

If you just want a low level graphics api, and you don’t care about some of the abstractions Vulkan offers, you might consider checking out Deko 3D. It’s a stripped down version of Vulkan for the NVidia Tegra X1
