Image Generator:

  • Origin is viewer’s eye
  • OpenGL right-handed camera-like coordinate system +X = right, +Y= up, +Z back
  • Unit Millimeter

Model:

  • Panadome Screen
  • generated with VIOSO
    • R=3000mm, left: -90°, right 90°, lower -20°, upper 70°
    • Axes: +X right, +Y up, +Z back
  • Platform pivot is 750mm below mid-point of sphere
  • Eye is 600mm above and 350mm left of platform pivot

The simulator’s axes and scale are identical to VIOSO, thus the rotation/scale part of the matrix, which is the upper 3×3 is Identity.

The pivot (rotation center) is 750mm below model origin, so a position input of (0,0,0) must become (0,-750,0) this is realized by setting t=(0,-750,0).

1 0 0 0
0 1 0 0
0 0 1 0
0 -750 0 1
base=[1,0,0,0;0,1,0,0;0,0,1,0;0,-750,0,1]

Eye is in IG coordinates. So set it to (-350,600,0)

eye=[-350,600,0]

Don’t forget to set
