hexaInterpolation¶

pyvsim.Utils.hexaInterpolation(p, hexapoints, values)[source]¶

This function interpolates values given on vertices of an hexahedron to a point. The algorithm relies on the ratio of volumes of tetrahedrons defined by the hexa faces and the point, and its behavior is approximately linear.

Warning - there is no verification whether the points are inside the hexahedron. One must check it using other methods.

Parameters :	p : numpy.ndarray \((N,3)\) List of points to be interpolated hexapoints : numpy.ndarray \((8,3)\) List of points defining the hexahedron values : numpy.ndarray \((M,3)\) List of values at the vertices of the hexahedron
Returns :	interpolated : numpy.ndarray \((N,M)\) Values interpolated at points p
