Report

The gpu raycasting implementation is the same approach as the Stegmaier one but with some minor changes and simplifications:

  • GLSL shaders
  • The volume is a cube: width, height and depth are all the same.
  • Proxy geometry (the six quads or the cube) is normalized and translated so the center its the same as the center of the scene.

Controls

  • Left click plus mouse movement to rotate the camera around the volume.
  • Right click to show the context menu.
  • Middle click plus vertical movement to increase/decrease the density window width.
  • Middle click plus horizontal movement to move right/left the density window.
