typedef std::vector< osg::ref_ptr<osg::Vec3Array> > osgSim::SphereSegment::LineList |
A list of vertex arrays representing a list of lines.
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));
osgSim::SphereSegment::SphereSegment | ( | ) | [inline] |
Default constructor.

Construct by angle ranges. Note that the azimuth 'zero' is the Y axis; specifying an azimuth range from azMin -osgPI/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.
