Constructor Details

InstancingManager

public InstancingManager()

Method Details

registerMesh

public void registerMesh(Mesh mesh)

Register a mesh for instancing for this current frame (internal use only)

Parameters:

mesh - the mesh to register

fillTransformBuffer

protected FloatBuffer fillTransformBuffer()

Fill the buffer with the transforms and return it

Returns:

the transform buffer

getPrimitiveCount

public int getPrimitiveCount()

Returns the number of meshes to be drawn in this batch. This function is only valid after the apply call (internal use only)

Returns:

the number of meshes to be drawn in this batch

getMaxBatchSize

public int getMaxBatchSize()

Split the batch in multiple batches if number of visible meshes exceeds this amount. Using larger batches will lead to better performance, although you might overflow the uniform space of the shader/videocard (crashes)

Returns:

maximum batch size

setMaxBatchSize

public void setMaxBatchSize(int maxBatchSize)

Split the batch in multiple batches if number of visible meshes exceeds this amount. Using larger batches will lead to better performance, although you might overflow the uniform space of the shader/videocard (crashes)

Parameters:

maxBatchSize - maximum batch size

isAddedToRenderQueue

public boolean isAddedToRenderQueue()

apply

public boolean apply(Mesh mesh,
 Renderer renderer,
 GLSLShaderObjectsState shader)

Applies all instancing info to the mesh and returns if the current render call is allowed to continue

Parameters:

mesh - the mesh

renderer - the renderer

shader - the shader

Returns:

continue rendering or skip rendering all together
