Still Life with Dots

• The virtual camera is at the origin (i.e. design eyepoint), looking toward its default position:
  • forward (center of bowl, i.e. downward in theater) -Z,
  • screen up (azimuth=zero?) is +Y
  • screen right is +X
• The scene is a cubical box with "radius" 20 units (so the box edge length is 40),
  • centered on the origin,
  • with a unit-cell grid of dots (or spheres) on each face.
• The dots on each face are a different color:
  • white on -Z face
  • red on +X face
  • green on +Y face
  • yellow on -X face
  • blue on -Y face
