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 (relevant blog post: CT scan viewer ) but I finally decided to use the 3D texture based method that was much faster.
