virtual RGBColor rcrt::TracingStrategy::trace

(

Ray &

r

)

const [pure virtual]

Trace the given ray and return the (approximated) radiance that is coming in at the ray origin, from -ray_direction.

Parameters:

r

the ray

Returns:

the radiance

Implemented in rcrt::BIHTracer, rcrt::DebugTracer, rcrt::PhotonTracer, rcrt::RayCaster, rcrt::SimpleTracer, rcrt::StereoMetaTracer, rcrt::SuperMetaTracer, and rcrt::ThreadedMetaTracer.

Referenced by trace(), rcrt::ThreadedMetaTracer::trace(), rcrt::SuperMetaTracer::trace(), rcrt::StereoMetaTracer::trace(), and rcrt::ThreadedMetaTracer::traceJob().

Image rcrt::TracingStrategy::trace

(

Camera *

cam

)

const [virtual]

Trace the full resolution of the given camera. Uses trace(Ray& r).

Parameters:

cam

The camera.

Returns:

An Image with the size of the cams resolution

Reimplemented in rcrt::StereoMetaTracer.

		const int &	x0,
		const int &	y0,
		const int &	x1,
		const int &	y1
	)			const [virtual]

Trace only the area specified by (x_0, y_0) and (x_1, y_1) of the given camera.

Parameters:

cam

The camera.

Returns:

An Image with the size of the specified area. (x_0, y_0) ~> (0,0) in the image.

Reimplemented in rcrt::StereoMetaTracer, rcrt::SuperMetaTracer, and rcrt::ThreadedMetaTracer.
