• Raycasting
  • 2005
    • A Simple and Flexible Volume Rendering Framework for Graphics-Hardware-based Raycasting link
      • Single path raycasting volume rendering
        • eliminate the necessity for intermediate buffer reads and writes
        • low geometry processing
        • adaptive step sizes (including early ray termination and empty space skipping) -> avoiding artifact
      • Framework
        • coordinate the two-step rendering process
        • computation of gradient (central differences or 3x3x3 Sobel operator)
      • Quality > Performance
