node10 boygrouping

acl(admin devvvv vvvvgroup)


  • multiple views on the same scene in one renderer
  • each viewport can have its own transformations
  • all rendering is done per viewport, not graphevaluation!
  • applications: side-by-side stereo, quadview (left, top, bottom, free), show details of scene
  • ViewPort Transform, Transformations Index, Crop Transform
  • display different stuff in different viewports

DirectX Devices

  • memory of textures/meshes is allocated per device (doubled memory use on single card if in dualview)
  • VideoTexture (EX9.Texture) only runs on one device!
  • span mode: one dx-device spanning multiple monitors
  • dual view: one dx-device per monitor
  • Device (EX9 Auto)
  • /dda 1

Camera Perspective

  • as long as 2d content, never mind
  • with 3d content perspective is important
  • every projector cannot have its own perspective
  • the whole view must be one spectator-perspective
    • it only looks correct for the spectator from one point
    • compare cave (headtracking) also only correct for one position!
  • scene has to be rendered with one perspective
  • throw it back onto a virtual replica of the screen
  • view it again from the virtual perspective of the real projector
  • perspective problems
    • with very wide views (unrealistic distortions on the sides)
      • special case t-gallery: perspective not per projector, but per object
    • with circular views
  • spectator vs. projector
