sqlraytracer VS cgltf

My pet silliness in sql from a couple years ago: https://github.com/chunky/sqlraytracer

You remind me I need to finish my hunt the wumpus implementation. (sqlite has an easy way to get user input, mid query...)

sql raytracer

Every time I see a discussion about raytracing, I feel compelled to link to my own, unreasonably silly, implementation: https://github.com/chunky/sqlraytracer

I implemented my raytracer by working through "Raytracing in One Weekend" and I would *highly* recommend it.

Someone built a raytracing engine in pure SQL https://github.com/chunky/sqlraytracer

This is awesome. A bit of self-promotion: I, too, wrote a deliberately obtuse raytracer: https://github.com/chunky/sqlraytracer

The only thing that's awkward about postgres is that it is documented as fully materialising a recursive CTE before handing you any rows. If you have some truly offensively large graph traversal [output, not input], it can take a while to create the temp table. My sql raytracer can take minutes per image because of the gargantuan temp storage thing.

[1] I used SQL: https://github.com/chunky/sqlraytracer [note that dielectrics still aren't working, don't judge me for bugs, yet!]

If you want to go all the way, https://learnopengl.com/ is a favorite around here. You could build a glTF viewer from scratch starting from that tutorial and https://github.com/jkuhlmann/cgltf and eventually building towards https://google.github.io/filament/Filament.html or whatever wacky artsy direction you like.

Use https://github.com/jkuhlmann/cgltf to parse the files. https://github.com/ocornut/imgui for your UI. Maybe https://www.libsdl.org/ just to set up a window, handle mouse clicks and initialize the GL context in that window.

Use glTF and https://github.com/jkuhlmann/cgltf Or, looks like you are using C#, so https://github.com/vpenades/SharpGLTF

Do you really have to use fbx? An open format like gltf is better supported, and there are bazillions loaders(I use cgltf without any issues, which is also used by raylib, Unigine and bgfx). It's also a perfect fit for OpenGL.

I recently discovered this pattern in cgltf (https://github.com/jkuhlmann/cgltf), and I agree, it makes deployment so much nicer.

Use https://github.com/jkuhlmann/cgltf It’s the most popular loader.

It's easy to generate a BVH for a generated triangle set (like a fractal pyramid or a dense cube). But, quickly generating a high quality BVH for a loaded model requires some research. Use https://github.com/jkuhlmann/cgltf to load models.

Write a simple glTF viewer in OpenGL. This is a throw-away warm-up. So, don't fret over the code. Don't do anything complicated. Shoot for a simple, forward renderer for a simple, animated character with trivial Phong lighting, diffuse map, normal map and a basic directional shadow map. Use OpenGL ES 3.0/GL 4.3 API with no crazy features. Don't worry about performance. Use https://github.com/jkuhlmann/cgltf to load the files. KTX is a great container for textures.
