virtual

◆ _getMeshRef()

MeshPtr& Ogre::InstanceBatch::_getMeshRef ( )

inline

◆ _setInstancesPerBatch()

void Ogre::InstanceBatch::_setInstancesPerBatch ( size_t instancesPerBatch )

Raises an exception if trying to change it after being built.

◆ _getIndexToBoneMap()

const Mesh::IndexMap* Ogre::InstanceBatch::_getIndexToBoneMap ( ) const

inline

◆ _supportsSkeletalAnimation()

bool Ogre::InstanceBatch::_supportsSkeletalAnimation ( ) const

inline

Returns true if this technique supports skeletal animation.

Remarks: A virtual function could have been used, but using a simple variable overridden by the derived class is faster than virtual call overhead. And both are clean ways of implementing it.

◆ _updateBounds()

void Ogre::InstanceBatch::_updateBounds ( void )

See also: InstanceManager::updateDirtyBatches

◆ calculateMaxNumInstances() [1/5]

virtual size_t Ogre::InstanceBatch::calculateMaxNumInstances	(	const SubMesh *	baseSubMesh,
		uint16	flags
	)		const

pure virtual

Some techniques have a limit on how many instances can be done.

Sometimes even depends on the material being used.

: Note this is a helper function, as such it takes a submesh base to compute the parameters, instead of using the object's own. This allows querying for a technique without requiering to actually build it.

Parameters

baseSubMesh	The base submesh that will be using to build it.
flags	Flags to pass to the InstanceManager.

See also: InstanceManagerFlags

Returns: The max instances limit

Implemented in Ogre::InstanceBatchVTF, Ogre::InstanceBatchHW_VTF, Ogre::InstanceBatchShader, and Ogre::InstanceBatchHW.

◆ build()

virtual RenderOperation Ogre::InstanceBatch::build ( const SubMesh * baseSubMesh )

virtual

Constructs all the data needed to use this batch, as well as the InstanceEntities.

Placed here because in the constructor virtual tables may not have been yet filled.

Parameters

baseSubMesh A sub mesh which the instances will be based upon from.

Remarks: Call this only ONCE. This is done automatically by Ogre::InstanceManager Caller is responsable for freeing buffers in this RenderOperation Buffers inside the RenderOp may be null if the built failed.

Returns: A render operation which is very useful to pass to other InstanceBatches (

See also: buildFrom) so that they share the same vertex buffers and indices, when possible

◆ buildFrom() [1/4]

virtual void Ogre::InstanceBatch::buildFrom	(	const SubMesh *	baseSubMesh,
		const RenderOperation &	renderOperation
	)

virtual

Instancing consumes significantly more GPU memory than regular rendering methods.

However, multiple batches can share most, if not all, of the vertex & index buffers to save memory. Derived classes are free to overload this method to manipulate what to reference from Render Op. For example, Hardware based instancing uses it's own vertex buffer for the last source binding, but shares the other sources.

Parameters

renderOperation The RenderOp to reference.

Remarks: Caller is responsable for freeing buffers passed as input arguments This function replaces the need to call build()

Reimplemented in Ogre::BaseInstanceBatchVTF, Ogre::InstanceBatchShader, and Ogre::InstanceBatchHW.

◆ _getMeshReference()

◆ isBatchUnused()

bool Ogre::InstanceBatch::isBatchUnused ( void ) const

inline

Returns true if it no instanced entity has been requested or all of them have been removed.

◆ getInstancedEntitiesInUse()

void Ogre::InstanceBatch::getInstancedEntitiesInUse	(	InstancedEntityVec &	outEntities,
		CustomParamsVec &	outParams
	)

Fills the input vector with the instances that are currently being used or were requested.

Used for defragmentation,

See also: InstanceManager::defragmentBatches

◆ _defragmentBatch()

void Ogre::InstanceBatch::_defragmentBatch	(	bool	optimizeCulling,
		InstancedEntityVec &	usedEntities,
		CustomParamsVec &	usedParams
	)

See also: InstanceManager::defragmentBatches This function takes InstancedEntities and pushes back all entities it can fit here Extra entities in mUnusedEntities are destroyed (so that used + unused = mInstancedEntities.size())

Parameters

optimizeCulling	true will call the DoCull version, false the NoCull
usedEntities	Array of InstancedEntities to parent with this batch. Those reparented are removed from this input vector
usedParams	Array of Custom parameters correlated with the InstancedEntities in usedEntities. They follow the fate of the entities in that vector.

Remarks: : This function assumes caller holds data to mInstancedEntities! Otherwise you can get memory leaks. Don't call this directly if you don't know what you're doing!

◆ _defragmentBatchDiscard()

void Ogre::InstanceBatch::_defragmentBatchDiscard ( void )

See also: InstanceManager::_defragmentBatchDiscard Destroys unused entities and clears the mInstancedEntity container which avoids leaving dangling pointers from reparented InstancedEntities Usually called before deleting this pointer. Don't call directly!

◆ _boundsDirty() [1/3]

virtual void Ogre::InstanceBatch::_boundsDirty ( void )

virtual

Called by InstancedEntity(s) to tell us we need to update the bounds (we touch the SceneNode so the SceneManager aknowledges such change)

Reimplemented in Ogre::InstanceBatchHW_VTF, and Ogre::InstanceBatchHW.

◆ setStaticAndUpdate() [1/3]

virtual void Ogre::InstanceBatch::setStaticAndUpdate ( bool bStatic )

inlinevirtual

Tells this batch to stop updating animations, positions, rotations, and display all it's active instances.

Currently only InstanceBatchHW & InstanceBatchHW_VTF support it. This option makes the batch behave pretty much like Static Geometry, but with the GPU RAM memory advantages (less VRAM, less bandwidth) and not LOD support. Very useful for billboards of trees, repeating vegetation, etc.

Remarks: This function moves a lot of processing time from the CPU to the GPU. If the GPU is already a bottleneck, you may see a decrease in performance instead! Call this function again (with bStatic=true) if you've made a change to an InstancedEntity and wish this change to take effect. Be sure to call this after you've set all your instances

See also: InstanceBatchHW::setStaticAndUpdate

Reimplemented in Ogre::InstanceBatchHW_VTF, and Ogre::InstanceBatchHW.

◆ isStatic() [1/3]

virtual bool Ogre::InstanceBatch::isStatic ( ) const

◆ removeInstancedEntity()

void Ogre::InstanceBatch::removeInstancedEntity ( InstancedEntity * instancedEntity )

Removes an InstancedEntity from the scene retrieved with getNewInstancedEntity, putting back into a queue.

Remarks: Throws an exception if the instanced entity wasn't created by this batch Removed instanced entities save little CPU time, but not GPU

◆ useBoneWorldMatrices() [1/2]

◆ _boundsDirty() [2/3]

void Ogre::InstanceBatchHW::_boundsDirty ( void )

virtual

Overloaded so that we don't perform needless updates when in static mode.

Also doing that could cause glitches with shadow mapping (since Ogre thinks we're small/bigger than we really are when displaying, or that we're somewhere else)

Reimplemented from Ogre::InstanceBatch.

◆ setStaticAndUpdate() [2/3]

void Ogre::InstanceBatchHW::setStaticAndUpdate ( bool bStatic )

virtual

See also: InstanceBatch::setStaticAndUpdate. While this flag is true, no individual per-entity cull check is made. This means if the camera is looking at only one instance, all instances are sent to the vertex shader (unlike when this flag is false). This saves a lot of CPU power and a bit of bus bandwidth.

Reimplemented from Ogre::InstanceBatch.

◆ isStatic() [2/3]

See also: setStaticAndUpdate

Reimplemented from Ogre::InstanceBatch.

◆ getWorldTransforms() [1/3]

virtual

Gets the world transform matrix / matrices for this renderable object.

Remarks: If the object has any derived transforms, these are expected to be up to date as long as all the SceneNode structures have been updated before this is called.

: This method will populate transform with 1 matrix if it does not use vertex blending. If it does use vertex blending it will fill the passed in pointer with an array of matrices, the length being the value returned from getNumWorldTransforms.

Note: Internal Ogre never supports non-affine matrix for world transform matrix/matrices, the behavior is undefined if returns non-affine matrix here.

See also: Matrix4::isAffine.

Implements Ogre::Renderable.

◆ getNumWorldTransforms() [1/3]

unsigned short Ogre::InstanceBatchHW::getNumWorldTransforms ( void ) const

virtual

Returns the number of world transform matrices this renderable requires.

Remarks: When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

Reimplemented from Ogre::Renderable.

◆ _updateRenderQueue() [2/5]

inline

Sets the state of the usage of bone matrix lookup.

Under default condition each instance entity is assigned a specific area in the vertex texture for bone matrix data. When turned on the amount of area in the vertex texture assigned for bone matrix data will be relative to the amount of unique animation states. Instanced entities sharing the same animation state will share the same area in the matrix. The specific position of each entity is placed in the vertex data and added in a second phase in the shader.

Note this feature only works in VTF_HW for now. This value needs to be set before adding any instanced entities

◆ shareTransformWith()

bool Ogre::InstancedEntity::shareTransformWith ( InstancedEntity * slave )

Shares the entire transformation with another InstancedEntity.

This is useful when a mesh has more than one submeshes, therefore creating multiple InstanceManagers (one for each submesh). With this function, sharing makes the skeleton to be shared (less memory) and updated once (performance optimization). Note that one InstancedEntity (i.e. submesh 0) must be chosen as "master" which will share with the other instanced entities (i.e. submeshes 1-N) which are called "slaves"

: Requirements to share trasnformations: Both InstancedEntities must have use the same skeleton An InstancedEntity can't be both "master" and "slave" at the same time

Remarks: Sharing does nothing if the original mesh doesn't have a skeleton When an InstancedEntity is removed (

See also: InstanceBatch::removeInstancedEntity), it stops sharing the transform. If the instanced entity was the master one, all it's slaves stop sharing and start having their own transform too.

Parameters

slave The InstancedEntity that should share with us and become our slave

Returns: true if successfully shared (may fail if they aren't skeletally animated)

◆ stopSharingTransform()

void Ogre::InstancedEntity::stopSharingTransform ( )

◆ setCustomParam()

void Ogre::InstancedEntity::setCustomParam	(	unsigned char	idx,
		const Vector4 &	newParam
	)

Sets the custom parameter for this instance.

See also: InstanceManager::setNumCustomParams Because not all techniques support custom params, and some users may not need it while using millions of InstancedEntities, the params have been detached from InstancedEntity and stored in it's InstanceBatch instead, to reduce memory overhead.

Remarks: If this function is never called, all instances default to Vector4::ZERO. Watch out! If you destroy an instanced entity and then create it again (remember! Instanced entities are pre-allocated) it's custom param will contain the old value when it was destroyed.

Parameters

idx	of the param. In the range [0; InstanceManager::getNumCustomParams())
newParam	New parameter

◆ getCustomParam()

const Vector4& Ogre::InstancedEntity::getCustomParam ( unsigned char idx )

◆ BatchSettings()

Ogre::InstanceManager::BatchSettings::BatchSettings ( )

inline

◆ InstanceManager()

		const String &	groupName,
		InstancingTechnique	instancingTechnique,
		uint16	instancingFlags,
		size_t	instancesPerBatch,
		unsigned short	subMeshIdx,

◆ setInstancesPerBatch()

void Ogre::InstanceManager::setInstancesPerBatch ( size_t instancesPerBatch )

Raises an exception if trying to change it after creating the first InstancedEntity.

Remarks: The actual value may be less if the technique doesn't support having so much

See also: getMaxOrBestNumInstancesPerBatches for the usefulness of this function

Parameters

instancesPerBatch New instances per batch number

◆ setMaxLookupTableInstances()

void Ogre::InstanceManager::setMaxLookupTableInstances ( size_t maxLookupTableInstances )

Sets the size of the lookup table for techniques supporting bone lookup table.

Raises an exception if trying to change it after creating the first InstancedEntity. Setting this value below the number of unique (non-sharing) entity instance animations will produce a crash during runtime. Setting this value above will increase memory consumption and reduce framerate.

Remarks: The value should be as close but not below the actual value.

Parameters

maxLookupTableInstances New size of the lookup table

◆ setNumCustomParams()

void Ogre::InstanceManager::setNumCustomParams ( unsigned char numCustomParams )

Sets the number of custom parameters per instance.

Some techniques (i.e. HWInstancingBasic) support this, but not all of them. They also may have limitations to the max number. All instancing implementations assume each instance param is a Vector4 (4 floats).

Remarks: This function cannot be called after the first batch has been created. Otherwise it will raise an exception. If the technique doesn't support custom params, it will raise an exception at the time of building the first InstanceBatch.

HWInstancingBasic: Each custom params adds an additional float4 TEXCOORD. HWInstancingVTF: Not implemented. (Recommendation: Implement this as an additional float4 VTF fetch) TextureVTF: Not implemented. (see HWInstancingVTF's recommendation) ShaderBased: Not supported.

Parameters

numCustomParams Number of custom parameters each instance will have. Default: 0

◆ getNumCustomParams()

unsigned char Ogre::InstanceManager::getNumCustomParams ( ) const

inline

◆ getInstancingTechnique()

InstancingTechnique Ogre::InstanceManager::getInstancingTechnique ( ) const

inline

Returns: Instancing technique this manager was created for. Can't be changed after creation

References Ogre::BLANKSTRING.

◆ getMaxOrBestNumInstancesPerBatch()

size_t Ogre::InstanceManager::getMaxOrBestNumInstancesPerBatch	(	const String &	materialName,
		size_t	suggestedSize,
		uint16	flags
	)

Calculates the maximum (or the best amount, depending on flags) of instances per batch given the suggested size for the technique this manager was created for.

Remarks: This is done automatically when creating an instanced entity, but this function in conjunction with

See also: setInstancesPerBatch allows more flexible control over the amount of instances per batch

Parameters

materialName	Name of the material to base on
suggestedSize	Suggested amount of instances per batch
flags	Flags to pass to the InstanceManager.

See also: InstanceManagerFlags

Returns: The max/best amount of instances per batch given the suggested size and flags

◆ createInstancedEntity() [2/2]

InstancedEntity* Ogre::InstanceManager::createInstancedEntity ( const String & materialName )

Creates an InstancedEntity based on an existing InstanceManager (.

See also: createInstanceManager)

Remarks: Return value may be null if the InstanceManger technique isn't supported Try to keep the number of entities with different materials to a minimum For more information

See also: InstancedManager; InstancedBatch,; InstancedEntity Alternatively you can call InstancedManager::createInstanceEntity using the returned pointer from createInstanceManager

Parameters

materialName	Material name
managerName	Name of the instance manager

Returns: An InstancedEntity ready to be attached to a SceneNode

◆ cleanupEmptyBatches()

void Ogre::InstanceManager::cleanupEmptyBatches ( void )

This function can be useful to improve CPU speed after having too many instances created, which where now removed, thus freeing many batches with zero used Instanced Entities However the batches aren't automatically removed from memory until the InstanceManager is destroyed, or this function is called.

This function removes those batches which are completely unused (only wasting memory).

◆ defragmentBatches()

void Ogre::InstanceManager::defragmentBatches ( bool optimizeCulling )

After creating many entities (which turns in many batches) and then removing entities that are in the middle of these batches, there might be many batches with many free entities.

Worst case scenario, there could be left one batch per entity. Imagine there can be 80 entities per batch, there are 80 batches, making a total of 6400 entities. Then 6320 of those entities are removed in a very specific way, which leads to having 80 batches, 80 entities, and GPU vertex shader still needs to process 6400! This is called fragmentation. This function reparents the InstancedEntities to fewer batches, in this case leaving only one batch with 80 entities

Remarks: This function takes time. Make sure to call this only when you're sure there's too much of fragmentation and you won't be creating more InstancedEntities soon Also in many cases cleanupEmptyBatches() ought to be enough Defragmentation is done per material Static batches won't be defragmented. If you want to degragment them, set them to dynamic again, and switch back to static after calling this function.

Parameters

optimizeCulling When true, entities close together will be reorganized in the same batch for more efficient CPU culling. This can take more CPU time. You want this to be false if you now you're entities are moving very randomly which tends them to get separated and spread all over the scene (which nullifies any CPU culling)

◆ setSetting()

void Ogre::InstanceManager::setSetting	(	BatchSettingId	id,
		bool	enabled,
		const String &	materialName = `BLANKSTRING`
	)

Applies a setting for all batches using the same material_ existing ones and those that will be created in the future.

: For example setSetting( BatchSetting::CAST_SHADOWS, false ) disables shadow casting for all instanced entities (

See also: MovableObject::setCastShadow)

: For example setSetting( BatchSetting::SHOW_BOUNDINGBOX, true, "MyMat" ) will display the bounding box of the batch (not individual InstancedEntities) from all batches using material "MyMat"

Note: If the material name hasn't been used, the settings are still stored This allows setting up batches before they get even created.

Parameters

id	Setting Id to setup,

See also: BatchSettings::BatchSettingId

Parameters

enabled	Boolean value. It's meaning depends on the id.
materialName	When Blank, the setting is applied to all existing materials

◆ getSetting()

bool Ogre::InstanceManager::getSetting	(	BatchSettingId	id,
		const String &	materialName
	)		const

If settings for the given material didn't exist, default value is returned.

◆ hasSettings()

bool Ogre::InstanceManager::hasSettings ( const String & materialName ) const

inline

Returns true if settings were already created for the given material name.

If false is returned, it means getSetting will return default settings.

◆ setBatchesAsStaticAndUpdate()

void Ogre::InstanceManager::setBatchesAsStaticAndUpdate ( bool bStatic )

Tells this batch to stop updating animations, positions, rotations, and display all it's active instances.

Currently only InstanceBatchHW & InstanceBatchHW_VTF support it. This option makes the batch behave pretty much like Static Geometry, but with the GPU RAM memory advantages (less VRAM, less bandwidth) and not LOD support. Very useful for billboards of trees, repeating vegetation, etc.

Remarks: This function moves a lot of processing time from the CPU to the GPU. If the GPU is already a bottleneck, you may see a decrease in performance instead! Call this function again (with bStatic=true) if you've made a change to an InstancedEntity and wish this change to take effect. Be sure to call this after you've set all your instances

See also: InstanceBatchHW::setStaticAndUpdate

◆ _addDirtyBatch()

void Ogre::InstanceManager::_addDirtyBatch ( InstanceBatch * dirtyBatch )

Called by an InstanceBatch when it requests their bounds to be updated for proper culling.

Parameters

dirtyBatch The batch which is dirty, usually same as caller.

◆ _updateDirtyBatches()

void Ogre::InstanceManager::_updateDirtyBatches ( void )

Called by SceneManager when we told it we have at least one dirty batch.

◆ getInstanceBatchMapIterator()

InstanceBatchMapIterator Ogre::InstanceManager::getInstanceBatchMapIterator ( void ) const

inline

Get non-updateable iterator over instance batches per material.

◆ getInstanceBatchIterator()

InstanceBatchIterator Ogre::InstanceManager::getInstanceBatchIterator ( const String & materialName ) const

inline

Get non-updateable iterator over instance batches for given material.

Remarks: Each InstanceBatch pointer may be modified for low level usage (i.e. setCustomParameter), but there's no synchronization mechanism when multithreading or creating more instances, that's up to the user.
