Member Function Documentation

virtual void makVrv::DtSpeedTreeForest::removeTree

(

DtUniqueID

record

)

[virtual]

Remove a tree from the forest.

Reimplemented from makVrv::DtOsgForest.

virtual void makVrv::DtSpeedTreeForest::setTreeClippingPlane

(

float

fFar

)

[virtual]

Set the distance that trees are clipped.

Since trees are expensive, they have their own clipping distances.

Reimplemented from makVrv::DtOsgForest.

virtual void makVrv::DtSpeedTreeForest::setTreeLodDistances	(	float	fNear,
		float	fFar
	)		[virtual]

Set the distances for tree LOD's.

float fNear - This parameter represents the distance from the camera where the highest LOD (1.0) begins. Trees that are closer to the camera than this distance retain a 1.0 LOD. Trees farther away than this distance are assigned an LOD value approaching 0.0 as they move toward the far LOD plane. fNear is set using world units, determine solely by the application. float fFar - This parameter represents the distance from the camera where the lowest LOD (0.0) begins. Trees that are farther from the camera than this distance retain a 0.0 LOD. Trees closer than this distance are assigned an LOD value approaching 1.0 as they move toward the near LOD plane. fFar is set using world units, determine solely by the application.

Reimplemented from makVrv::DtOsgForest.

virtual void makVrv::DtSpeedTreeForest::setPerformanceProfile

(

int

profile

)

[virtual]

Set the performance profile for the forest.

Reimplemented from makVrv::DtOsgForest.

virtual void makVrv::DtSpeedTreeForest::addUniqueTree

(

const DtTreeRecord &

record

)

[virtual]

Add a tree to the forest.

Reimplemented from makVrv::DtOsgForest.

virtual DtSpeedTreeModelInstance* makVrv::DtSpeedTreeForest::findSpeedTreeModelInstance

(

const std::string &

modelDef

)

[virtual]

Find a DtSpeedTreeModelInstance from the model definition name.

bool makVrv::DtSpeedTreeForest::makeContextCurrent

(

)

Attempt to make a context current.

virtual void makVrv::DtSpeedTreeForest::slot_treeModelInstanceToBeDestroyed

(

const std::string &

modelDef

)

[protected, virtual]

Called when the model instance for a particular model definition is about to be destroyed.

Reimplemented from makVrv::DtOsgForest.

virtual void makVrv::DtSpeedTreeForest::slot_treeModelInstanceCreated

(

const std::string &

modelDef

)

[protected, virtual]

Called when the model instance for a particular model definition is created.

Reimplemented from makVrv::DtOsgForest.

virtual DtTreeModel* makVrv::DtSpeedTreeForest::castUpdaterToTreeModel

(

DtAgentUpdateResolverInterface *

updater

)

[protected, virtual]

Casts a DtAgentUpdateResolverInterface to a DtSpeedTreeModel.

Reimplemented from makVrv::DtForestObject.

virtual bool makVrv::DtSpeedTreeForest::createTree

(

const DtTreeRecord &

record

)

[protected, virtual]

No-op. Always returns true.

Reimplemented from makVrv::DtOsgForest.
