Sampler Class Reference
#include <MapExtractorInterface.h>
Class Description
This is a base class for a sampler node, which can generate some data for a given target-source surface point pair.
There are different types of samplers (for example displacement, normal etc..) and the map extractor node has one instance of all the available types of classes inherited from the Sampler class. Each of these instances has an utilizer node attached to it, which gets the data calculated by the sampler. The user can turn on/off them all separately. Those which are turned off are ignored during the extraction. The enabled ones will be used to calculate data for each of the target-source location pair. Usually the sampler is calculating the data for the current target-source pair only (for example in case of vector displacement, it simply calculates the difference between the two locations in the space as a vector) but the sampler can also do batch procession of the location pairs, store them in a temporary array, and later only read those values from the array and return them in the ProcessSurfacePoint function. In this case the sampler must catch the eventQueueLocated using the OnPhaseEvent virtual function, and do the preprocessing then.
