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 really helped a lot when building my semi-sphere skyblock base in minecraft.

I appreciate all effort that you put into this. Get export option as WaveFront /obj file / or LDraw Model will be handful.

This is super handy thanks so much. It would be really cool if there was a way to save the schematics for some of the bigger projects.

Hahaha! When I posted this comment it refreshed the page, making the schematics for Beizer Cube I was working on vanish.

Love this! I bookmarked it for future use. I only have one question though. I generated a 52 by 25 by 52 hollow dome, and there is a missing layer on top where there is a hole in the roof. This is no issue, I can easily patch it up, was just wondering why.

Any way to export these to a schematica file? Maybe have a generic drop down box to select your material of choice then export the object.

Make it so its full screen and you can actually scroll and fit it to your screen properly its too small when working with 300+ block spheres

Is there any way you could turn up the contrast a little?
