LearnOpenGL.FSharp
Exercises based on the https://learnopengl.com/ tutorials, using F# and SILK.NET as the OpenGL wrapper. Each title that has a link is pointing to the original chapter from the learnopengl.com site, in which the theory is explained and all of the math is being copied from.
This repo can be useful if you are following the excelent tutorials on your own and get stuck on some of them (pointer manipulation is a bitch), but please note that this code is not supposed to set any guideline about how you should structure your own projects. It´s just the result of me trying to learn OpenGL, F#, FRP and functional programming in general, so expect the code to be suboptimal at best.
Also note that the 'Galante' library i wrote here is just a set of helpers i needed along the way and will need a complete refactor once i have a better understanding about OpenGl, but that´s not likely to happen within this repo.
From exercise 47 and onward, DearImGui is used to display an informative overlay, but this seems to be working only in my PC for some reason. I don't know what's going on (might be driver related) but I'll try to get it to work properly.

This one looks kind of weird because the images are not centered vertically, the intention is to be forced to realize that rotations in OpenGL are calculated taking the origin as the rotation center (and not the object's center) and if a rotation of an object is needed around itself, then said object must be translated to the origin, rotated and then translated back to it's initial position, which may be somewhat counterintuitive.
Coordinate systems

Note how the reflection of the light moves on each face of the cube when the camera moves.

Note that although this light source looks similar as in the previous examples, this time it's not reaching the objects that are too far away from it, giving a more realisting feel to the source.
