PrtEngine.ComputeSuperClusters(Int32[],Mesh,Int32,Int32[]) Method (Microsoft.DirectX.Direct3D)

  • Article

Used with compressed results of the vertex version of the precomputed radiance transfer (PRT) simulator. Generates "superclusters," which are groups of clusters that can be drawn in the same draw call. A greedy algorithm that minimizes overdraw is used to group the clusters.

Parameters

clusterIds System.Int32[]
An array of cluster identifiers (IDs) extracted from a compressed buffer by calling PrtCompressedBuffer.ExtractClusterIDs.
scene Microsoft.DirectX.Direct3D.Mesh
A Mesh that represents the composite scene passed to the simulator.
maxNumberClusters System.Int32
Maximum number of clusters allocated per super cluster.
superClusterIds System.Int32[]
An integer array that contains the index of the super cluster to which the corresponding cluster was assigned.

Return Value

System.Int32
Number of super clusters allocated.
