A SphereSegment is a Geode to represent an portion of a sphere (potentially the whole sphere).
The sphere is aligned such that the line through the sphere's poles is parallel to the z axis. The sphere segment may be rendered various components switched on or off:
- The specified area of the sphere surface.
- An edge line around the boundary of the specified area
of the sphere surface.
- Four <i>spokes</i>, where a spoke is the line from
the sphere's centre to a corner of the rendered area.
- Four planar areas, where the planar areas are formed
between the spokes.
Caveats:
- It's worth noting that the line through the sphere's poles is
parallel to the z axis. This has implications when specifying the
area to be rendered, and specifying areas where the centre of
the rendered area <i>is</i> the Z axis may lead to unexpected
geometry.
- It's possible to render the whole sphere by specifying elevation
and azimuth ranges round the full 360 degrees. When doing
so you may consider switching the planes, spokes, and edge lines
off, to avoid rendering artefacts, e.g. the upper and lower
planes will be coincident.
