C# Класс Axiom.Core.InstancedGeometry

Pre-transforms and batches up meshes for efficient use as instanced geometry in a scene Shader instancing allows to save both memory and draw calls. While StaticGeometry stores 500 times the same object in a batch to display 500 objects, this shader instancing implementation stores only 80 times the object, and then re-uses the vertex data with different shader parameter. Although you save memory, you make more draw call. However, you still make less draw calls than if you were rendering each object independently. Plus, you can move the batched objects independently of one another which you cannot do with StaticGeometry.

Метод Описание
AddEntity ( Entity ent, Vector3 position ) : void
AddEntity ( Entity ent, Vector3 position, Quaternion orientation ) : void
AddEntity ( Entity ent, Vector3 position, Quaternion orientation, Vector3 scale ) : void

Adds an Entity to the static geometry. This method takes an existing Entity and adds its details to the list of elements to include when building. Note that the Entity itself is not copied or referenced in this method; an Entity is passed simply so that you can change the materials of attached SubEntity objects if you want. You can add the same Entity instance multiple times with different material settings completely safely, and destroy the Entity before destroying this InstancedGeometry if you like. The Entity passed in is simply Must be called before 'Build'.

AddEntity ( Entity ent, Vector3 position, Vector3 scale ) : void
AddSceneNode ( SceneNode node ) : void

adds all the Entity objects attached to a SceneNode and all it's children to the static geometry. This method performs just like addEntity, except it adds all the entities attached to an entire sub-tree to the geometry. The position / orientation / scale parameters are taken from the node structure instead of being specified manually.

DetermineGeometry ( SubMesh sm ) : List

Look up or calculate the geometry data to use for this SubMesh
InstancedGeometry ( SceneManager owner, String name ) : System
SplitGeometry ( VertexData vd, IndexData id, Axiom.Core.SubMeshLodGeometryLink &targetGeomLink ) : void

Split some shared geometry into dedicated geometry.
