virtual bool DtTriangleOutputInterface::processTriangles ( ) const

virtual

Will only call processTriangle(const DtTerrainTriangleStruct& triangle) if this returns true.

Reimplemented in DtDebugDrawTerrainOutputInterface.

virtual void DtTriangleOutputInterface::processTriangle ( const DtTerrainTriangleStruct & triangle )

pure virtual

Called on each triangle.

Note: This function may be called simultaneously from multiple threads. Implementation must be reentrant.

Implemented in DtDebugDrawTerrainOutputInterface.

virtual void DtTriangleOutputInterface::processTerrainInstance ( const DtTerrainInstance & instanceStruct )

virtual

Called for each geometry instance when processing data in a terrain if enableTerrainInstanceProcessing is enabled. Default implementation does nothing.

Reimplemented in DtDebugDrawTerrainWithInstancesOutputInterface.

virtual bool DtTriangleOutputInterface::processAABBs ( ) const

virtual

AABB functions will only be called if this returns true. Returns false by default.

Reimplemented in DtDebugDrawTerrainOutputInterface.

virtual void DtTriangleOutputInterface::queryAABB	(	const DtVector &	min,
		const DtVector &	max,
		const DtCoordTransform &	toLocal
	)

virtual

Called with the axis-aligned bounding box values computed for the query.

Reimplemented in DtDebugDrawTerrainOutputInterface.

virtual bool DtTriangleOutputInterface::objectAABB	(	const DtVector &	min,
		const DtVector &	max,
		const DtCoordTransform &	toLocal
	)

virtual

Called with the axis-aligned bounding box of each object processed. These AABBs are calculated in the coordinate system in which the query is done.

Returns: Can reject objects from further processing by returning false.

Reimplemented in DtDebugDrawTerrainOutputInterface.

virtual bool DtTriangleOutputInterface::enableTerrainInstanceProcessing ( ) const

virtual

If this returns true, processTerrainInstance() will be called for each instance geometry encountered in the terrain. If this is false, instance geometries will be unrolled into triangles, and processTriange() will be called for each triangle in each instance. Default implementation returns false.

Reimplemented in DtDebugDrawTerrainWithInstancesOutputInterface.

virtual bool DtTriangleOutputInterface::processElevationTiles ( ) const

virtual

elevationTile() functions will only be called if this returns true.

Reimplemented in DtDebugDrawTerrainOutputInterface.

virtual bool DtTriangleOutputInterface::elevationTile	(	const DtVector &	p1,
		const DtVector &	p2,
		const DtVector &	p3,
		const DtVector &	p4
	)

virtual

Corner points of an elevation tile.

Returns: Can reject tiles from further processing by returning false.

Reimplemented in DtDebugDrawTerrainOutputInterface.

virtual bool DtTriangleOutputInterface::processElevationPosts ( ) const

virtual

elevationPost() will be called if this is true

Reimplemented in DtDebugDrawTerrainOutputInterface.

virtual bool DtTriangleOutputInterface::elevationPost ( std::vector< DtPoint > & postArray )

virtual

List of grid post points with elevation.

Returns: the grid post of an elevation tile

Reimplemented in DtDebugDrawTerrainOutputInterface.

virtual bool DtTriangleOutputInterface::forcePaging ( ) const

virtual

This will force paging in of all terrain within the box, which may take a significant amount of time and may also consume large amounts of memory. Default returns true.

Reimplemented in DtDebugDrawTerrainOutputInterface.

virtual void DtTriangleOutputInterface::setFailure ( const std::string & reason )

virtual

Called by implementation if there is an error.

virtual bool DtTriangleOutputInterface::shouldExit ( ) const

virtual

Called by implementation to allow early exit. Functions will return as soon as possible if this returns true.

Reimplemented in DtDebugDrawTerrainOutputInterface.

virtual void DtTriangleOutputInterface::setName ( const std::string & name )

virtual

Set terrain area name.

virtual std::string& DtTriangleOutputInterface::name ( )

virtual

Return the terrain area name.
