VolumeDataViewSampler

Direct Known Subclasses:

AveragingRadialSampler

public abstract class AbstractRadialSampler
extends AbstractVolumeDataViewSampler

This class provides support for peforming samples across the volume from a given center to each vertex. Implementing classes must implement traceValue(...) which is called for each point in the node for the given volume.

computeValues

public void computeValues(float[] coords,
                          VolumeDataView volDataView,
                          int time,
                          double[] outValues)

Description copied from interface: VolumeDataViewSampler

Samples the given coordinates and puts the resulting samples in the outValues array.

Parameters:

coords - an array of input coordinates of the following form: [x0, y0, z0, x1, y1, z1, ...]

volDataView - a view upon a volume data set to be sampled

time - the time index to perform the sampling

outValues - an allocated array of size coords.length / 3, the array does not need to be zero-initialized; samples values are returned through this array in the following form: [s0, s1, ...]

traceValue

protected abstract double traceValue(VolumeDataView volDataView,
                                     int time,
                                     javax.vecmath.Point3f center,
                                     javax.vecmath.Point3f destPoint)

Traces a line from the center to the destination point at the given time for the given volume data view. This method is called using the same center across each volume data view for each destination point in the current cutaway node. Implementers should return a value to represent the value at the destination point.

Parameters:

volDataView -

time -

center -

destPoint -

Returns:
