Constructor & Destructor Documentation

◆ ThinLensCamera()

ph::ThinLensCamera::ThinLensCamera	(	float64	lensRadius,
		float64	focalDistance,
		const math::Vector2D &	sensorSize,
		const math::Transform *	rasterToSensor,
		const math::RigidTransform *	cameraToWorld )

Parameters

lensRadius	Radius of the thin lens.

◆ receiveRay()

math::Spectrum ph::ThinLensCamera::receiveRay	(	const math::Vector2D &	rasterCoord,
		Ray *	out_ray ) const

overridevirtual

Generate a ray received by the receiver.

Given raster coordinates, generate a corresponding ray that would have hit that location from the light entry of the receiver. The light entry would be the outmost surface of a camera's lens system for example. This method is for Monte-Carlo sampling.

Returns: A weighting factor for the received quantity. Proper sensor response and sampling PDF are included in the returned weight.
