Volume Rendering using CUDA ¨C Transfer Function & Anti-Aliasing

Here are some pictures of my GPU-based volume rendering engine:

Included functions:

1. Anti-Aliasing (not applied in the above picture)
2. Transfer Function on Alpha & Color

The highlight is that it reaches an interactive FPS: for 512x512 resolution it is about 20~40 FPS, depending on how much the volume takes the screen.
