BilateralBlur Class Reference

Apply an approximate bilateral blur to a texture. This can be used to blur while preserving edges, or even to upscale and blur a small texture. The approximate implementation in Rendu is based on the one demonstrated in G3D (McGuire M., Mara M., Majercik Z., http://casual-effects.com/g3d, 2017), and relies on a separable Gaussian blur with adjusted weights and an extra step distance.

Constructor & Destructor Documentation

BilateralBlur()

BilateralBlur::BilateralBlur

(

const std::string &

name

)

Constructor.

Parameters

name	debug name for internal buffers

Member Function Documentation

process()

void BilateralBlur::process	(	const glm::mat4 &	projection,
		const Texture &	src,
		const Texture &	depthTex,
		const Texture &	normalTex,
		Texture &	dst
	)

Apply the bilateral blur to a texture and write the result in a texture.

Note

It is possible to use the same texture as input and output.

Parameters

projection	the camera projection matrix
src	the texture to blur/upscale
depthTex	the depth texture
normalTex	the view-space normal texture
dst	the destination texture

resize()

void BilateralBlur::resize ( uint  width, uint  height  )

private

Resize the internal intermediate buffers.

Parameters

width	the new resolution width
height	the new resolution height
