Methods

AllocBuffer(Int32, Func<RTHandleSystem, Int32, RTHandle>, Int32)

Allocate RT handles for a buffer.

Declaration
public void AllocBuffer(int bufferId, Func<RTHandleSystem, int, RTHandle> allocator, int bufferCount)
Parameters
Type Name Description
Int32 bufferId

The buffer to allocate.
Func<RTHandleSystem, Int32, RTHandle> allocator

The functor to use for allocation.
Int32 bufferCount

The number of RT handles for this buffer.

CalculateRatioAgainstMaxSize(Int32, Int32)

Returns the ratio against the current target's max resolution

Declaration
public Vector2 CalculateRatioAgainstMaxSize(int width, int height)
Parameters
Type Name Description
Int32 width

width to utilize
Int32 height

height to utilize
Returns
Type Description
Vector2

retruns the width,height / maxTargetSize.xy ratio.

Dispose()

Dispose implementation

Declaration
public void Dispose()

GetFrameRT(Int32, Int32)

Declaration
public RTHandle GetFrameRT(int bufferId, int frameIndex)
Parameters
Type Name Description
Int32 bufferId

Defines the buffer to use.
Int32 frameIndex
Returns
Type Description
RTHandle

The frame RT or null when the bufferId was not previously allocated (AllocBuffer(Int32, Func<RTHandleSystem, Int32, RTHandle>, Int32)).

GetNumFramesAllocated(Int32)

Queries the number of RT handle buffers allocated for a buffer ID.
