Constructor & Destructor Documentation

LaplacianIntegrator()

LaplacianIntegrator::LaplacianIntegrator	(	uint	width,
		uint	height,
		uint	downscaling
	)

Constructor.

Parameters

width	internal processing width
height	internal processing height
downscaling	downscaling factor for the internal convolution pyramid resolution

Member Function Documentation

preprocId()

const Texture * LaplacianIntegrator::preprocId ( ) const

inline

The ID of the texture containing the laplacian field.

Returns

the laplacian texture ID.

process()

void LaplacianIntegrator::process

(

const Texture &

texture

)

Filter a given input texture, first computing its laplacian field before performing integration.

Parameters

texture

the GPU ID of the texture

resize()

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

Resize the internal buffers.

Parameters

width	the new width
height	the new height

texture()

const Texture * LaplacianIntegrator::texture ( ) const

inline

The ID of the texture containing the integration result.

Returns

the result texture ID.
