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.

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

Constructor & Destructor Documentation

osgSim::SphereSegment::SphereSegment ( )
inline

Default constructor.

osgSim::SphereSegment::SphereSegment ( const osg::Vec3 centre,
float  radius,
float  azMin,
float  azMax,
float  elevMin,
float  elevMax,
int  density 
)
inline

Construct by angle ranges.

Note that the azimuth 'zero' is the Y axis; specifying an azimuth range from azMin -osg::PI/2.0f to azMax osg::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
centresphere centre
radiusradius of sphere
azMinazimuth minimum
azMaxazimuth maximum
elevMinelevation minimum
elevMaxelevation maximum
densitynumber of units to divide the azimuth and elevation ranges into
osgSim::SphereSegment::SphereSegment ( const osg::Vec3 centre,
float  radius,
const osg::Vec3 vec,
float  azRange,
float  elevRange,
int  density 
)

Construct by vector.

Parameters
centresphere centre
radiusradius of sphere
vecvector pointing from sphere centre to centre point of rendered area on sphere surface
azRangeazimuth range in radians (with centre along vec)
elevRangeelevation range in radians (with centre along vec)

Member Function Documentation

LineList osgSim::SphereSegment::computeIntersection ( const osg::Matrixd matrix,
osg::Node subgraph 
)

Compute the interesection lines between subgraph and this sphere segment.

The matrix is the transform that takes the subgraph into the same coordiante frame as the sphere segment. The resulting intersections are in the coordinate frame of the sphere segment.

LineList osgSim::SphereSegment::computeIntersection ( const osg::Matrixd matrix,
osg::Drawable drawable 
)

Compute the interesection lines between specified drawable and this sphere segment.

The matrix is the transform that takes the subgraph into the same coordiante frame as the sphere segment. The resulting intersections are in the coordinate frame of the sphere segment.

osg::Node* osgSim::SphereSegment::computeIntersectionSubgraph ( const osg::Matrixd matrix,
osg::Node subgraph 
)

Compute the interesection lines between subgraph and this sphere segment.

The matrix is the transform that takes the subgraph into the same coordiante frame as the sphere segment. The resulting intersections are in the coordinate frame of the sphere segment.

osg::Node* osgSim::SphereSegment::computeIntersectionSubgraph ( const osg::Matrixd matrix,
osg::Drawable drawable 
)

Compute the interesection lines between specified drawable and this sphere segment.

The matrix is the transform that takes the subgraph into the same coordiante frame as the sphere segment. The resulting intersections are in the coordinate frame of the sphere segment.
