  • It’s not really ‘right’ or ‘wrong’ it’s under a fixed set of assumptions. You raise a valid point. What does happen to the top and the bottom? I was ignoring them considering only the sides in the two most extreme cases.

    If I understand your case when the can is flatted the area gets much larger and when it gets taller it shrinks to a pin point. An equally valid approach

    Quick ‘proof’ the taller the can, the more material used:

    Consider two cases ignoring the top and bottom only focussing on the surface area. In the first case, you flatten so much the can has no height. This forms a ring that when unwrapped makes a length of 2 pi R.

    Now stretch the can to be ‘infinitely’ long. By construction, this is longer than 2 pi r. Given both are made of aluminum, and have the same density, the larger can has more mass requiring more material.

    The total mass must be a continuous function ranging from the linear mass density times the circumference of the circle to the same mass density time times the ‘length’ of the infinite line. This must remain true for any small increase in length between the two.

    I’ll leave this as an exercise to the reader. What if the circle has an infinite radius?

















  • Interesting idea to take “non-programmers (such as artists)” out of their normal professional workflows (e.g. adobe creative) and putting them in yours for the sake of productivity. What hardware are we talking about? Are you running a vm? That won’t work on apple silicon. (Which creative types overwhelmingly use)

    Bonus question: You “want to develop a game” and are “considering collaborating with others”? What’s the scale and where are we at with making the game? Because worrying about your team’s workflow sounds a lot like having that $10 million idea and buying a domain name before writing a line of code.

    That said, I’ve done this kind of thing before. Pick something. Anything. And write scripts to automate most of it. You will never get a 100% turn key solution, and everything has a tradeoff. Solve enough of the problem and go work on your game.
