Class BatchDistanceRayCasting

java.lang.Object

cz.fidentis.analyst.engines.face.batch.distance.impl.BatchIndirectDistanceImpl

cz.fidentis.analyst.engines.face.batch.distance.impl.BatchDistanceRayCasting

All Implemented Interfaces:

BatchDistance, BatchIndirectDistance

public class BatchDistanceRayCasting
extends BatchIndirectDistanceImpl

A class that computes similarity of a set of faces by casting rays in the diction of template face normals.

The computation is accelerated by using multiple CPU or possibly GPU cores concurrently.

Constructor Details

BatchDistanceRayCasting

public BatchDistanceRayCasting(HumanFace gaugeFace,
 int numFaces,
 com.jogamp.opengl.GLContext context)

Constructor.

Parameters:

gaugeFace - A face serving as a "gauge". It is usually an average face of a set of faces.

numFaces - The number of faces to be measured (excluding the gauge face)

context - Active OpenGL context on which makeCurrent() can be called. If this parameter is not null, then GPU will be used. Otherwise, regular CPU implementation is used.

Method Details

addToMeasurement

public void addToMeasurement(HumanFace face)

Description copied from interface: BatchIndirectDistance

Adds the face to the N:N measurement.

Specified by:

addToMeasurement in interface BatchIndirectDistance

Specified by:

addToMeasurement in class BatchIndirectDistanceImpl

Parameters:

face - Face to be measured
