Voxel Shape Generator

Written 11:36 am 7/4/2012 Modifed 10:09 pm 2/8/2015

Use this tool to make spheres for Minecraft and the like. Idea originally stolen from Neil Fraser, but more recently inspired by friendly competition with my friend Jesse, whose Circle Generator seems a little two dimensional.

Update (2/8/2015) Attempting to make this a little more bad-ass. See here

Update (3/14/2013) GUI makeover- I'm attempting to speed everything up by only rendering tables when you're ready for them. I also added isometric modeling (with culling this time) in canvas that should let you preview the shape.

Update (3/12/2013) You can now draw your own shape with Bezier curves! Adding SVG rendering methods for speed, although it's not as easy to read as tables. I'll try to make that work a bit better.

Update (9/30/2012) The script has been updated to generate cones and domes. If you have any suggestions, add them to the comments.

This site isn't great, it's missing some blocks for some reason, and I built the entire thing to realize it was quite off when I followed these exact steps so now I have to restart and do it all myself smh

It only counts the surface area, not the inside of it.

What do the blue blocks mean?

Would it be possible to generate voxel polygons? Like a pentagon, hexagon, etc., or things like an icosahedron as well?

Awesome Web app.

Doesn't quite work perfectly on mobile.

Which is a pity, as I'd love to use it with this use case: Minecraft Fullscreen, Mobile phone with this open to glance at when need to.

You could use squares not rectangles, it would be a lot easier. But overall, it’s pretty good and will help me a lot with my Death Star.

I'm also building a Death Star ????. How big is yours? My measurements were 49

Please update so it can take slabs/stairs into account for smoother curves!

What do you mean with slabs/staris? do you mean minecraft, 'cus this one is for voxels and not blocks
