Hollow Sphere Creator (think JJK Domain Expansion)

robertbarron

I'm looking for guidance on how to go about creating a shell around me using psi. I don't need it to have any effect, but I would prefer the radius be more than 6 blocks. I don't even know if this is feasible in psi, but any tips would be greatly appreciated.

This would be a struggle, since you would have to manage raycasts in multiple directions... I would say your best option is to use a loopcast or circle spell to make a pseudo-sphere, which is basically a sphere that isn't really a sphere. You could manage that by doing some weird vector calculations, but that make block placements would also cost a stupid amount of energy and take a while either way. I wouldn't recommend it to be honest. It is possible though.

It could be possible using spherical coordinates, but it would still be quite hard. a cylinder would be easy because you only need polar coordinates and a height, which could move one down/up by using the loopcast index and the modulo operator. But to build a sphere efficiently you'd need to find a way to construct it top to bottom without placing a block at a position twice. Because every layer of the sphere contains a diffrent number of blocks the modulo ist too useful either. It's a nice challenge but probably even perfectly optimised it would take a good while and the sphere wouldn't be very good even for minecraft standards.

Here's the Imgur Album with a video and the trick

This has been a brain worm for me for a while now and I finally was able to recreate it.
It simply makes a vector at the start with the desired radius of the sphere and on each step it rotates it by a number that doesn't cleanly divide 360 but is also different on each axis.

I copied this twice and simply added an offset of 180º to the second one to make it twice as fast, unfortunately it's still really slow, it's faster if you have a smaller radius
