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.
renderOperation | The RenderOp to reference. |
Reimplemented in Ogre::BaseInstanceBatchVTF, Ogre::InstanceBatchShader, and Ogre::InstanceBatchHW.
|
private |
Called when batches are fully exhausted (can't return more instances) so a new batch is created.
For the first time use, it can take big build time. It takes care of getting the render operation which will be shared by further batches, which decreases their build time, and prevents GPU RAM from skyrocketing.

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
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) |

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

void Ogre::InstanceManager::setInstancesPerBatch | ( | size_t | instancesPerBatch | ) |
Raises an exception if trying to change it after creating the first InstancedEntity.

void Ogre::InstancedEntity::setInUse | ( | bool | used | ) |
Sets whether the entity is in use.
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.
maxLookupTableInstances | New size of the lookup table |
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).
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.
numCustomParams | Number of custom parameters each instance will have. Default: 0 |

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.

When the mesh is (hardware) skinned, a different code path is called so that we reuse the index buffers and modify them in place.
For example Instance #2 with reference to bone #5 would have BlendIndex = 2 + 5 = 7 Everything is copied identically except the VES_BLEND_INDICES semantic

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"
slave | The InstancedEntity that should share with us and become our slave |
void Ogre::InstancedEntity::stopSharingTransform | ( | ) |
|
protected |
When this entity is a slave, stopSharingTransform delegates to this function.
nofityMaster = false is used to prevent iterator invalidation in specific cases.

Just unlinks, and tells our master we're no longer sharing.

Called when we you use a mesh which has shared vertices, the function creates separate vertex/index buffers and also recreates the bone assignments.
