I know that this is a long shot...

Is there any chance of having the sort of features that would be needed to manually tidy up the results of segmentations of 3D images (from CT scans). The sort of things I'm thinking about are.

1. The ability to overlay two voxel images in the same editing space (e.g. one for the original image and one for the segmentation with added alpha channels).

2. The ability to draw arbitrary sheets of voxels by e.g. selecting 3-4 voxels as the corners of the sheet.

3. In terms of image format one would need to handle images with e.g. float32 and int32 greyscale voxel values. Import and export of raw binary images would be nice.

Just wondering. Some of the proprietary 3D analysis suites have these editing features but as far as I know the FOSS solutions for 3D image processing don't include any editing functionality.

3D Slicer (http://www.slicer.org/) has most (if not all) of that, if I understood your questions. I have struggled with the learning curve, though. YouTube helps sometimes.

I haven't found the functionality to change the value of ability voxels in Slicer yet -- in particular for sheets with corners supplied by the user. Is it there and I'm just being dumb?

A friend created https://cubeteam.io/ but it failed pretty hard and fairly fast.

I pay attention to this space because I run https://Clara.io, which is a 3D editor, but in the spirit of 3DS Max, Maya, Blender rather than focused on voxels.

Incidentally, just as a piece of quick feedback for clara.io:

Registering for a service is really expensive! I have to come up with a password, then file it in my password manager, hand out my email address to some unknown stranger, etc, etc. Mostly I won't bother unless there's some compelling reason to do so; when present with a registration form I'll usually just give up.

Since you have a browser-based product, having 'Try now!' button that starts it (with no backend storage!) and let me play with it would make me way more likely to actually sign up.

Agree ! this looks like amazing app , please provide demo speed access to the app without registering.

Nice way to work in that plug

Any way to export to 3d file format ? Great work by the way ...

Yes, from the Readme:

Export to obj and pyl

This looks actually pretty cool and something I might want to use. Is there any way to load .ply/.vtk with the voxel structure description?
