Current Project Status
- Octree representation has been completed
- Wireframe surface outline is being drawn
- Slice rendering direction is changed inside the vessel, to reduce the amount of artifacts seen
- A more interactive transfer function has been added, using pixel shaders
- Animations now work
TODO
Han
Greg
- Implement a more interactive/responsive transfer function implementation using fragment shaders

- rendering lungs for virtual endoscopy
- segmentation methods
- touches on blood vessels in lungs - too small/intricate?

- seems relevant, no pdf
Vector field visualization
- Most vector field visualization are textures, “smoke” particles
- mostly seems to apply to fluids passing over solid objects (cars, airplanes)

- current (2009)
- looked mostly at section 4, 5 & the table at the beginning
