CT viewer - a tool to visualize Computed Tomography slices data in 3D.
A 3D volume renderer that can visualize Computed Tomography data. It uses a sigmoid-based
transfer function to perform the segmentation and 3D texture based volume rendering.
I had previously experimented with isosurfaces too (blog post: CT scan viewer ) but I finally decided to
use the 3D texture based method that was much faster.
