Method DownSample

DownSample(in CustomPassContext, RTHandle, RTHandle, int, int)

Convert the source buffer to an half resolution buffer and output it to the destination buffer.

Declaration

public static void DownSample(in CustomPassContext ctx, RTHandle source, RTHandle destination, int sourceMip = 0, int destMip = 0)

Parameters

Type	Name	Description
CustomPassContext	ctx	Custom Pass Context.
RTHandle	source	Source to use for the downsample
RTHandle	destination	Destination buffer of the downsample
int	sourceMip	Source mip level to sample from.
int	destMip	Destination mip level to write to.

DownSample(in CustomPassContext, RTHandle, RTHandle, Vector4, Vector4, int, int)

Convert the source buffer to an half resolution buffer and output it to the destination buffer.

Declaration

public static void DownSample(in CustomPassContext ctx, RTHandle source, RTHandle destination, Vector4 sourceScaleBias, Vector4 destScaleBias, int sourceMip = 0, int destMip = 0)

Parameters

Type	Name	Description
CustomPassContext	ctx	Custom Pass Context.
RTHandle	source	Source to use for the downsample
RTHandle	destination	Destination buffer of the downsample
Vector4	sourceScaleBias	Scale and bias to apply when sampling the source buffer
Vector4	destScaleBias	Scale and bias to apply when writing into the destination buffer. It's scale is relative to the destination buffer, so if you want an half res downsampling into a fullres buffer you need to specify a scale of 0.5;0,5. If your buffer is already half res Then 1;1 scale works.
int	sourceMip	Source mip level to sample from.
int	destMip	Destination mip level to write to.
