3D medical data sets, from PET scans and such, are indeed huge in size. Typically GB's of voxel data. The sort of thing that requires an overnight download unfortunately.
One possible optimization is to recreate the 3D vertex set from a series of 2D texture images, by interpolating vertex positions between frames. Surprisingly only a small subset of images is needed to recreate the resulting 3D geometry, but the tessellation calculations are pretty math intensive.
- nkassis 16y agoWow, I didn't know someone at Robarts was doing this stuff( I work for McGill another University in Canada ;p) I'll have to communicate with him. I've managed to get some full volumes loaded in my app. It was a scan of my brain. That work ok (slow and takes a few minutes to load) but when I loaded the brain or a rat, my app totally crashed. To be fair the rats brain was at a higher resolution :)
