3d-game-shaders-for-beginners
🎮 A step-by-step guide to implementing SSAO, depth of field, lighting, normal mapping, and more for your 3D game.
Some tutorials I have looked at (well nor originally, as I learned the basics when we were still at DX9 :D): - https://lettier.github.io/3d-game-shaders-for-beginners/index.html

Project mention: Creating a simple 3d engine to render a car for ML, how hard is it? Sim | reddit.com/r/cpp | 2021-12-16
http://www.open3d.org/ seems like a good choice. Is there anything better I'm missing?

Meshlab

I don't think this is an issue with tinyobjloader but I'm unsure of how to troubleshoot from here. I've been following this tutorial to learn opengl.

Great question, and one I’m interested in too. I planned to look at a solution over the next couple of weeks. I was going to look at a library like this, https://github.com/PyMesh/PyMesh, which could automate it.

pioneerspacesim maybe. Probably not ideal, but that's the only thing I can think about now.

vive-diy-position-sensor
Code & schematics for position tracking sensor using HTC Vive's Lighthouse system and a Teensy board.
I was considering (and still am considering) building slimeVR trackers. However, I do own steamvr basestations and I kind of want to take advantage of that if possible. So I was curious whether there is a cheap diy method to base station based trackers. I did come across this: https://github.com/ashtuchkin/vive-diy-position-sensor However I have no clue to how well this actually works. Any ideas of what to do?

Some parts of the 3MF are actually good. I like the spec documents winding order of the meshes. The format includes units, and these optional 4x4 transformation matrices — both are useful.
As for need of the new formats, for one, modern CAD formats are insanely complex. These IGES/STEP/BREP files require many megabytes of very complicated code to deal with, such as this library https://github.com/tpaviot/oce These formats may even contain proprietary extensions. Also, they need non-trivial processing power to handle. Many people wouldn’t want a Core i7 with gigabytes of RAM in their 3D printers, inflates hardware cost and software complexity.
Besides, we now have high-resolution 3D scanners, and CAE software which algorithmically optimizes models by running numerical simulations. They both output triangle meshes instead of CAD files. Scanners often output point clouds one can convert into triangles, but hard to convert into CAD formats.
I just don’t like the 3MF implementation too much. XML is fine for kilobytes of data, but not many megabytes. If I would be designing that format, I would probably made it binary. Maybe EBML https://en.wikipedia.org/wiki/Extensible_Binary_Meta_Languag... would work for that; it does fine for MKV videos, which is also a huge pile of structured data with non-trivial performance constraints for producers and especially parsers.
Another minor thing, it was not the best idea to make name start with a digit. Most programming languages forbid identifiers like that for their classes / functions / namespaces / modules.

Alternatively, you can create a view per mip and use a compute shader to compute the whole cube at once. This is what I have been doing

Project mention: Is opengl good for writing game engines or is the smth better? C++ | reddit.com/r/cpp | 2021-01-22
Unfortunately not much info is publicly available about it. Recently a homebrew rendering API was released that builds upon reverse engineering efforts: https://github.com/devkitPro/deko3d.
