Member Function Documentation

void NullEmitter::init

(

)

[virtual]

Performs any initialization that may be necessary before beginning to use this Emitter.

Note:

initializes spectral power and radiant exitance to black

Reimplemented from Emitter.

Definition at line 14 of file NullEmitter.cpp.

SpectralSampleSet NullEmitter::getLe

(

const Vector3 &

wo

)

[virtual]

Returns:

the spectral radiance emitted along the given vector

Note:

returns SpectralSampleSet::black (null emitter)

Implements Emitter.

Definition at line 19 of file NullEmitter.cpp.

void NullEmitter::preview

(

Shape *

shape

)

[virtual]

Sets up OpenGL material state (light properties) to enable a crude/fast preview of this light in OpenGL.

Note:

overrides default implementation to not modify GL light state at all

Reimplemented from Emitter.

Definition at line 23 of file NullEmitter.cpp.
