The escalation to "visualizing the SDF of a 3D projection of a 4D box" near the end was quick :)

Sir you are a beast. Everytime my googling about raymarching gets concrete you appear in the results. Phenomenal work and resources you put out there, thank you so much!

That's the best explanation I've seen so far... Thank you!

That was great. The visual going from 2D to 3D to 4D was fantastic!

Are you planning on doing a series of these for the other primitives on your website? Would be really useful for basic understanding - as it's a lot better than just copying formulas. Also I don't have the brains to derive these myself! They aren't obvious, to me a least, but with explanation really make sense.

Great explanation, wonderful visualization, what a resource! Keep it up!

I echo the sentiment in the comments that I would adore a series of these videos covering each primitive, getting progressively more complex and building on previous videos! Thanks for the amazing work, IQ.

You are a true wizard, my friend. Continue to share the magic of numbers, as this wizardry is contagious to the mind of fellow thinkers.

Thanks, this was great, even the shading of the outside and inside of the shape, in the end, was purposeful.
