A class responsible for processing DtGeom3dLinesComponent objects.

This class does not own any components, it only processes components that are registered with it. The concept is that components are processed in one place so that opens up opportunities to burst multi-thread operations, and do things as a "system" such as turning on/off the entire system for specific operations.

To use a component with this system, call createComponent(). The caller is responsible for freeing the component. The caller does not have to register/unresister the component with this system as it is done automatically be the component itself.

You can access this system from DtRenderer.

virtual DtGeom3dLinesComponent* makVrv::DtGeom3dLinesSystem::createComponent ( DtModelSetId modelSet )

virtual

Creates and returns a component that is compatible with this system. The component will register itself with this system on creation. The component will un-register itself with this system on destruction. The system does not own the component. The caller of this createComponent() method will own the component and should destroy it when done with it. modelSet the modelset to associate with the component (see DtModelSetEnums.h)

virtual void makVrv::DtGeom3dLinesSystem::registerComponent ( DtGeom3dLinesComponent * component )

virtual

Registers the given component with this system. The system does not own the component. The system will perform operations on the component while it is registered.

virtual void makVrv::DtGeom3dLinesSystem::unregisterComponent ( DtGeom3dLinesComponent * component )

virtual

Un-Registers the given component with this system. The system does not own the component.

virtual size_t makVrv::DtGeom3dLinesSystem::registeredComponentCount ( const DtModelSetId modelSetId ) const

virtual

Returns the number of registered components for a specific model set.

Parameters

modelSetId the model set to check for (see DtModelSetEnums.h)

virtual double makVrv::DtGeom3dLinesSystem::computeAltitude	(	const DtVector &	point,
		bool &	geoCentric
	)		const

virtual

Utility method used by a component to compute the altitude at the given point. Also fills in the geoCentric as true if the coordinate system is geocentric.

Parameters

point	the vrv local point
geoCentric	(output) is set to true when coordinate conversion was geocentric

virtual bool makVrv::DtGeom3dLinesSystem::cull	(	void *	cameraContext,
		const DtModelSetId	modelSetId,
		const DtVector &	cameraPos,
		const Frustum_64 &	frustum
	)

virtual

Culls the 3d lines and prepares per camera context staging. Returns true is something is visible. This method can be called multi-threaded if the cameraContext is different for each calling thread.

Parameters

cameraContext	a context that can be used to associate a specific camera with a set of culled data
modelSetId	the model set to cull for (see DtModelSetEnums.h)
cameraPos	the camera position
frustum	the frustum to cull against

virtual void makVrv::DtGeom3dLinesSystem::submit3dLinesForDraw	(	void *	cameraContext,
		std::vector< Dt3dLinesStagingBuffer * > &	buffers
	)

virtual

Fills the 3d lines buffer for all non-culled components. Gathers buffers to draw that contain active lines.

Parameters

cameraContext	a context that can be used to associate a specific camera with a set of culled data
buffers	(out) the resulting staging buffers to render

virtual void makVrv::DtGeom3dLinesSystem::slot_coordinateSystemChanged ( )

protectedvirtual

Slot for when the coordinate system changes. This is needed to keep myCoordinateSystem up to date.

virtual void makVrv::DtGeom3dLinesSystem::slot_preTick ( )

protectedvirtual

Pre tick function. This is currently used to flush invalid camera's.

static bool makVrv::DtGeom3dLinesSystem::isSphereVisible	(	const std::array< DtVector4< double >, 6 > &	cullingPlanes,
		const DtVector3< double > &	center,
		double	radiusSquared
	)

staticprotected

non-virtual for inner loop Checks to see if the given sphere is visible in the culling planes. Returns true if visible. Calculations are in world (vantage space).

Parameters

cullingPlanes	the culling planes
center	the center of the sphere
radiusSquared	the sphere radius squared

static void makVrv::DtGeom3dLinesSystem::theCullJob ( void * data )

staticprotected

A cull job function used as a callback for job splitting. This is an internal function called from a tbb::parallel_for.
