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

typedef std::vector< osg::ref_ptr<osg::Vec3Array> > osgSim::SphereSegment::LineList

A list of vertex arrays representing a list of lines.

Member Enumeration Documentation

enum osgSim::SphereSegment::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.

1 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.
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	Draw every part of the sphere segment.

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

centre	sphere centre
radius	radius of sphere
azMin	azimuth minimum
azMax	azimuth maximum
elevMin	elevation minimum
elevMax	elevation maximum
density	number 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

centre	sphere centre
radius	radius of sphere
vec	vector pointing from sphere centre to centre point of rendered area on sphere surface
azRange	azimuth range in radians (with centre along vec)
elevRange	elevation range in radians (with centre along vec)
density	number of units to divide the azimuth and elevation ranges into

osgSim::SphereSegment::SphereSegment	(	const SphereSegment &	rhs,
		const osg::CopyOp &	co
	)

inline

Copy constructor.

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.
