Volumes/3d images in Jitter

Hi, I would like to build a kind of “3D volume explorer” in Jitter. Suppose
I have a 3D image or volume (common in medical imaging, MRI, CT, and the
like). In case you wonder what a 3D image is, imagine a stack of 2D images
one on top of each other. That’s what I mean.
So, I would like to be able to cut a slice through it in any direction (X, Y
or Z) and display it on screen, and also rotate and scale it. Ideally, I
would like to have the ability of cut a slice in any direction through the
volume and not only in a perpendicular way. In more formal terms, I would
like to intersect any 2D plane with this 3D volume and display the
intersection.
Are there any jitter objects or externals that do this kind of stuff? Should
I use opengl, although I would like to work with real 3D images and not
geometries? Is there an object that can handle 3D images?

Thanks!

Sounds very interesting, I’m sure someone on here will have some insight. I’m not sure how to manage the intersections you’re describing, though there probably is a straightforward way, maybe with some kind of camera or lookat message? Whatever people come up with I’ll be watching this thread with great interest. Lots of math education applications to the “slices” you’re talking about.

By “3D images” do you mean those created in another 3D application? If you can save as .obj in these apps then you can open them with jit.gl.model.

If you haven’t posted this to the Jitter forum, that might be a good idea too.

Hi, thanks for the forum suggestion. I thought this list was the only way to
get help with Jitter.By 3D I don’t mean a model, I mean pixels … (well,
voxels really). A stack of images.

Thanks!
