Constructs the continuous scatterplot for two given scalar point fields of a mesh.
The continuous scatterplot is an extension of the discrete scatterplot for continuous bi-variate analysis. This filter outputs an ExplicitDataSet of triangle-shaped cells, whose coordinates on the 2D plane represent respectively the values of both scalar fields. Triangles' points are associated with a scalar field, representing the density of values in the data domain. The filter tetrahedralizes the input dataset before operating.
If both fields provided don't have the same floating point precision, the output will have the precision of the first one of the pair.
This implementation is based on the algorithm presented in the publication :
S. Bachthaler and D. Weiskopf, "Continuous Scatterplots" in IEEE Transactions on Visualization and Computer Graphics, vol. 14, no. 6, pp. 1428-1435, Nov.-Dec. 2008 doi: 10.1109/TVCG.2008.119.
