Member Function Documentation

void BidirectionalPathTracer::sample

(

PointSample &

sample

)

[virtual]

Renders a single point sample (incident radiance evaluation) at the point specified on the film plane.

Notes: k = 2: only contribution is from directly visible lights (eye -> light) other paths won't match up with the incident direction (other vertex -> eye) k = 3:

Implements PointSampleRenderer.

Definition at line 40 of file BidirectionalPathTracer.cpp.

bool BidirectionalPathTracer::generate

(

Path &

outPath

)

[virtual]

Generates a complete, valid path from scratch.

Note:

path generated is assumed to start at an emitter (light) and end at a sensor (camera)

Returns:

true on success or false on failure (if an invalid path was encountered)

Implements IPathGenerator.

Definition at line 203 of file BidirectionalPathTracer.cpp.

void BidirectionalPathTracer::generateL

(

Path &

outPath

)

[virtual]

Generates a light subpath which is assumed to start at an emitter.

Implements IPathGenerator.

Definition at line 212 of file BidirectionalPathTracer.cpp.

void BidirectionalPathTracer::generateE

(

Path &

outPath

)

[virtual]

Generates an eye subpath which is assumed to end at a sensor.

Implements IPathGenerator.

Definition at line 224 of file BidirectionalPathTracer.cpp.

void BidirectionalPathTracer::generateE	(	Path &	outPath,
		bool	debug
	)			[virtual]

Definition at line 228 of file BidirectionalPathTracer.cpp.

void BidirectionalPathTracer::finalize

(

)

[virtual]

Called upon finishing a call to render.

Note:

Default implementation is blank

Reimplemented from PointSampleRenderer.
