Methods

AllocHistoryFrameRT(int, Func<string, int, RTHandleSystem, RTHandle>, int)

Allocates a history RTHandle with the unique identifier id.

Declaration

int	id	Unique id for this history buffer.
Func<string, int, RTHandleSystem, RTHandle>	allocator	Allocator function for the history RTHandle.
int	bufferCount	Number of buffer that should be allocated.

Returns

Type	Description
RTHandle	A new RTHandle.

GetCurrentFrameRT(int)

Returns the id RTHandle of the current frame.

Declaration

public RTHandle GetCurrentFrameRT(int id)

Parameters

Type	Name	Description
int	id	Id of the history RTHandle.

Returns

Type	Description
RTHandle	The RTHandle of the current frame.

GetOrCreate(Camera, int)

Get the existing HDCamera for the provided camera or create a new if it does not exist yet.
