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 artifacts, e.g. the upper and lower
  planes will be coincident.

◆ LineList

A list of vertex arrays representing a list of lines.

◆ DrawMask

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.

sphereSegment->setDrawMask(SphereSegment::DrawMask(SphereSegment::SURFACE|SphereSegment::SPOKES));
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.

Constructor & Destructor Documentation

◆ SphereSegment() [1/4]

osgSim::SphereSegment::SphereSegment ( )
inline

Default constructor.

◆ SphereSegment() [2/4]

osgSim::SphereSegment::SphereSegment ( const osg::Vec3 centre,
float  radius,
float  azMin,
float  azMax,

Construct by angle ranges. Note that the azimuth 'zero' is the Y axis; specifying an azimuth range from azMin -PI/2.0f to azMax PI/2.0f will cover the 'top half' of the circle in the XY plane. The elev angles are 'out' of the 'zero' XY plane with +ve angles above the plane, and -ve angles below.

Parameters

radiusradius of sphere
azMinazimuth minimum
azMaxazimuth maximum
elevMinelevation minimum
elevMaxelevation maximum
densitynumber of units to divide the azimuth and elevation ranges into
