Detailed Description

The sglCountSortedLightProcessor sacrifices some accuracy in the sort for speed comparible to the sglDefaultLightProcessor class. This class uses the counting sort, O(n+k), where the sort keys are truncated to k (num_bins) integer values.

sglCountSortedLightProcessor::~sglCountSortedLightProcessor ( ) [virtual]

Destructor.

Member Function Documentation

void sglCountSortedLightProcessor::reset ( ) [inline, virtual]

Resets the processor for the next frame (e.g. clears list of lights). Reimplemented from sglLightProcessor. Definition at line 171 of file sglLightProcessor.hpp.

virtual void sglCountSortedLightProcessor::addLight ( const sglMat4f & matrix, const sglLight * light ) [virtual]

Add a light for the current frame. Parameters: matrix   modelview matrix to be used when applying this light light   pointer to the new light Reimplemented from sglLightProcessor.

unsigned int sglCountSortedLightProcessor::getNumLights ( ) const [inline, virtual]

Query the number of lights collected while culling the current frame. Returns: the number of lights collected while culling the current frame. Reimplemented from sglLightProcessor. Definition at line 181 of file sglLightProcessor.hpp.

virtual void sglCountSortedLightProcessor::apply ( ) [virtual]

Applys the lights collected for this frame. Note: this will apply at most sgl::s_max_lights. Reimplemented from sglLightProcessor.
