In Step 1 the pixel distribution is

In Step 1 the pixel distribution is computed on the planar
surface using Equation 2. This pixel distribution forms the
base of the pipelines that is used to sample images to be
displayed on the curved display surface. In Step 2the pixel
distribution is computed on the spherical surface using the
same Equation 2. Note that pixel clouds computed on Step
1 and Step 2 are isomorphic.
The Voronoi tessellation of the spherical surface is computed in Step 3 forming a spherical mesh. The support material area around the mesh is computed in Step 4and polygons forming the top of the light pipes are computed. The
light pipes walls are extruded from the curved surface into
the bottom plane in Step 5 creating areas where support
material will be printed. The light pipes are filled with the
optical clear material in Step 6producing final model that is
3D printed.
