Detailed Description

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.

Member Typedef Documentation

A list of vertex arrays representing a list of lines.


Member Enumeration Documentation

DrawMask represents a bit field, the values of which may be OR'ed together to specify which parts of the sphere segment should be drawn.

E.g.

Enumerator:
SURFACE 

Draw the specified area on the sphere's surface.

SPOKES 

Draw the spokes from the sphere's centre to the surface's corners.

EDGELINE 

Draw the line round the edge of the area on the sphere's surface.

SIDES 

Draw the planes from the sphere's centre to the edge of the sphere's surface.

ALL
