Detailed Description

(Separated) 2D Bilateral Filter.

Although, bilateral filters are not mathematically separable, doing so gives a good approximation in exchange for reducing quadratic to linear run time and so is a common practice.

apply()

void G3D::BilateralFilter::apply	(	RenderDevice *	rd,
		const shared_ptr< Texture > &	source,
		const shared_ptr< Framebuffer > &	destination,
		const shared_ptr< GBuffer > &	gbuffer,
		const BilateralFilterSettings &	settings
	)		const

Applies a Bilateral Filter.

Handles intermediate storage in a texture of the same format as the source texture.

Assumes that the following fields are available:

• G3D::GBuffer::Field::CS_NORMAL (if normal weight or plane weight is nonzero)
• G3D::GBuffer::Field::DEPTH_AND_STENCIL (if depth weight or plane weight is nonzero)
• G3D::GBuffer::Field::GLOSSY (if glossy weight is nonzero)
