NurbsGenerator.EvaluateKnotSpanIntegralValue Method

NurbsGenerator EvaluateKnotSpanIntegralValue Method

Virtual Photonics - VTS Library

Virtual Photonics

Returns the integral of a NURBS curve over a single knotspan. If the integral has to be performed to evaluate ROfRho the algorithm checks if the lower time limit of the knot span is larger then the minimum time of flight necessary to reach the detector. The integration is analytical only for the real domain and only if the time span is larger then a threshold value and only if the value of the exponential decay due to absorption is larger then a threshold value.
