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

TODO

Han

Greg

• Implement a more interactive/responsive transfer function implementation using fragment shaders

  • link
  • 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)
