Constructor & Destructor Documentation

Constructs a new FrustumCulling pipeline.

Parameters

isForScene	True if the culling is for a scene, false for shadow maps.
meshInstancesArray	The array containing all mesh instance data.
pipelineId	The attached material pipeline id

static

Cleans up global resources shared by all FrustumCulling instances.

Dispatches the frustum culling compute shader.

Parameters

commandList	The command list to record the dispatch command into.
drawCommandsCount	The total number of draw commands to process.
view	The camera view matrix.
projection	The camera projection matrix.
instances	The buffer containing the instances to cull.
input	The buffer containing the input indirect draw commands.
output	The buffer where the visible indirect draw commands will be written.
counter	The buffer containing the counter for the number of visible instances.

uint32 getDrawCommandsCount ( ) const

Gets the number of instances that passed the frustum culling.
