Syntax

public static class SuperSamplingUtility

Methods

Downscale(CommandBuffer, RenderTargetIdentifier, RenderTargetIdentifier, int, int, SuperSamplingFactor)

Down samples a super resolution texture using pixel averaging where the sample kernel size is determined by the input super resolution scale factor.

Declaration

public static void Downscale(CommandBuffer cmd, RenderTargetIdentifier superResTexture, RenderTargetIdentifier outputTexture, int outputWidth, int outputHeight, SuperSamplingFactor scaleFactor)

Parameters

Type	Name	Description
CommandBuffer	cmd	The command buffer to enqueue to down scaling graphics commands to.
RenderTargetIdentifier	superResTexture	The input super resolution texture.
RenderTargetIdentifier	outputTexture	The output downscaled texture.
int	outputWidth	The width of the output downscaled texture.
int	outputHeight	The height of the output downscaled texture.
SuperSamplingFactor	scaleFactor	The scale factor between the super resolution texture and the output downscaled texture (scale factor == super res texture width / down scale texture width).

Examples

Downscaling a texture using a 4X scale factor would create a new downscaled texture that has dimensions one quarter of the magnitude of the input texture or 1/16th the total resolution. During the actual down sampling process, each pixel in the down scaled texture would correspond to a 4x4 block of pixels in the input super resolution texture that are averaged together into a single output pixel.
