transformRef

AccessorReadOnly

Return a (REFERENCE TO) the transform from world space to the mapped sphere space.

• This maps coordinates "relative to the sphere" to world.
• Its inverse maps world coordinates into the sphere space.
  • In the sphere space, an xyz (vector from origin) with magnitude equal to 1 is ON the sphere (hence its world image is ON the ellipsoid)
  • In the sphere space, an xyz (vector from origin) with magnitude less than 1 is INSIDE the sphere (hence its world image is INSIDE the ellipsoid)
  • In the sphere space, an xyz (vector from origin) with magnitude greater than 1 is OUTSIDE the sphere (hence its world image is OUTSIDE the ellipsoid)
