Use quilts to create volume regions.  This view is the same all 3 XYZ sides of the center cube.

 

View2.PNG

Trim and merge to look like this.

TIP: mapping does not work at the "poles" as seen by [Inspect]  [Mesh surface]  (shows U-V lines)

 

View2c.PNG

replace surface as shown (revolve around another axis then trim by surfaces like view 2 then patch)

confirm with [Inspect]  [Mesh surface] .

 

View3 Vols.PNG

Create volume regions by quilt until this.

Section view showing internal volume lines.

 

Map the normal way with bricks.

Tip: use RMB pick from list when it gets busy.

A hollow sphere proceeds exactly the same except the internal spherical surface must also have its U-V lines fixed.  (Center cube only for construction)

This also can produce the truncated quarter sphere.  (shown with 1 element per edge)
