◆ allocate()

virtual void G3D::Film::Filter::allocate	(	const String &	name,
		const shared_ptr< Texture > &	source,
		const shared_ptr< Framebuffer > &	argTarget,
		int	sourceDepthGuardBandThickness,
		const ImageFormat *	fmt = `ImageFormat::RGBA8()`
	)		const

protectedvirtualinherited

Called from apply().

Parameters

name
source
argTarget
sourceDepthGuardBandThickness
fmt	Format for target

Reimplemented in G3D::Film::TAAFilter.

◆ apply()

virtual void G3D::Film::FXAAFilter::apply	(	RenderDevice *	rd,
		const FilmSettings &	settings,
		const shared_ptr< Texture > &	source,
		const shared_ptr< Texture > &	motion,
		const shared_ptr< Framebuffer > &	target,
		int	sourceTrimBandThickness,
		int	sourceColorBandThickness
	)		const

overridevirtual

Apply the filter to source, writing to target.

The CompositeFilter and EffectsDisabledBlitFilter expect a guard band (if there is one specified in settings) on the input and produce output without a guard band. All other filters assume no guard band on input or output (and assert that). This works because exactly one of CompositeFilter or EffectsDisabledBlitFilter is always in the filter chain and always at the front.

If target is null, then all filters allocate an output that is the same size as the input (except for CompositeFilter removing the guard band). If target is not null, then the output is stretched to the size of target using bilinear interpolation.

Parameters

target If null, allocate intermediateResultFramebuffer and set this->target to it. If not null, set this->target = target

Implements G3D::Film::Filter.

◆ createShared()

template<class T , class ... ArgTypes>

static shared_ptr<T> G3D::ReferenceCountedObject::createShared ( ArgTypes &&... args )

inlinestaticprotectedinherited

Like std::make_shared, but works for protected constructors.

Call as createShared<myclass>.
