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.

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.

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

Four to five portions of this fruit juice should be consumed every week to have the desired result. He is content, and the complete opposite of what we think final years has in store for us.

I'm playing around with the one you have on new.oranj.io and it's really lovely, I love the thickness option. But, it is occasionally hard to use.

You need more colors/indicators, especially in plan mode.

Changes between plans, such as blocks that are not directly on top of old ones, or gaps where it was once solid, need to be indicated, possibly with some sort of outline.

Perhaps, the orginal base could also be marked, for larger projects this will help the builders orient themselves.
