On the nail

If there's any interest I would like to share it, if only for the "import all files in folder" thing. But how should I go about sharing it? A Github repo? Or somewhere inside Overleaf?

For example, to get light and shadows, your shader should have access to some (probably global) variable about the position and direction of eg. a spotlight. Very often composite lighthing is achieved by combining multiple shader passes (a base pass for global ilumination, and one for each light for example), each literally adding more light (additive pass). Now, in order to avoid adding light for pixels where the light source is blocked (ie. shadow) the most common technique is using what's called a Z-buffer (just a floating point texture). You want to know for each light in the scene where their light reaches, so (before all lighting is applied) you set up a single shader pass that combines all solid geometry on the scene and using the light position and direction as the camera transform, and use a special shader whose only purpose is writing the objects distance to the Z-buffer. Now, every time you want to know whether a point in space is reached by your light, you go about sampling this Z-buffer (after doing some geometry) and compare the point's distance to the saved value in that direction. Yes, it can be very buggy and precision errors abound, and every engine worth their salt already does this for you, but lets you get in there and modify the process.

Everything else are variations on this theme. Deferred rendering is rendering data instead of colors into an intermediate texture which is later processed to get the colors. Blur effects are 2D convolutions of the rendertexture (eg by a Gaussing kernel). Tesseletion shaders are about generation new geometry in the vertext shader. Even drawing text is achieved through font atlasing and small rectangles.

Shouldn't it be "There are 1.44 standard minutes in 1 metric minute" ?

I believe we can talk about two ways of anthropomorphisation: assigning feelings to things in our mental model of it, or actually trying to emulate human-like thought processes and reactions in its design. It made me wonder when will models come out that are trained to behave, say, villainously. Not just act the part in transparent dialogue, but actually behave in destructive manners. Eg putting on a facade to hear your problems and then subtly mess with your head and denigrate you.

For comparison, the initial value of the iteration (1.2) would be 85% accurate, which without context might sounds like a lot but is pretty abysmal
