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.

It would be nice if we could download each layer as an img because it's hard to see the whole thing when you are making something big (485, 485, 485 in my case)

Could you make the self design one more design-able so it could be a bit more complex with multiple curves???

I have been looking for a way to rotate 3d objects (not necessarily curved) in minecraft. Specifically, I want to make a pyramid with a cap that has (in appearance) levitated and spun on it's center axis to a degree of my choosing. I regularly use sites like this (and building guides in modded minecraft) to make curves, but to make something complex (like a spaceship crashing into the ground at an angle for instance) still escapes me. I have no idea how this could be done, but I am hoping some math enthusiast would be willing to tackle this problem in a relatively simple to use program. Any takers?

Assuming that the pyramid base (which is a square) is "straight" (I.e. Has a slope of 0) the Slope of the 4 lines of the cap base would be tan(a pi/180) and -cot(a pi/180) two of each and a is the wanted degree

Go to the Google Calculator and you'll find cot and tan

Could you make an ovoid generator? It would be perfect for my project.

Just uncheck the 'lock ratios' box near the measurements, then you can change them freely into ovoids.

It will be awesome if you add a Tetrahedron generator. triangle are hard to do with square ;)

Meh all u need is 4 equally distant points then you pretty much made it but I like the way u lean to Platonic solids, they should make a regular polyhedron generater where u choose how many faces it have

I haven't been checking the comment section recently- Looks like the spam bots got a little out of hand. Used to just filter out any posts with a URL in it, now I must have to get smarter...

Just used this tool to build a 90X90 block circle by 60 block high dome out of glass. Looks wicked. Thanks for the help!

Is there a way to change the central coordinate of a sphere to (0,0,0)?

Not sure how to delete a post, but I retract the question. I was thinking about being able to input a starting point coordinate from Minecraft for example and then have the program calculate map coordinates for me relative to that point. Based on the way I build or excavate my shapes, it's relatively easy to do this manually.

Love this tool. I've used it for many projects.

I've built a couple of awesome domes using this. Thank you so much! I've got a new idea for a much larger structure (mwahh ha ha). A zoom tool would be a huge help though (no pun intended).
