Any chance you can comment on the question I had left about the mapping and how to produce a version of the graph at the head of the page?

Thanks

@Joshua You should start by looking at some examples of the volumeutils package and see how (for instance) the NoiseSurface demo is building up a volume using purely a mathematical function. Just remember that this Gray-Scott implementation is only in the XY plane (2D) and imagine the Z axis to be time. So create a voxel space and then populate it with 2D slice data (with the Gray-Scott updated for each slice). Then calculate an IsoSurface and render it as TriangleMesh. The upcoming 0020 release will have some demos in this direction…

@desnos Erm.. is this page not qualifying as a tutorial for you? Also there’re several examples about this specific technique bundled with the library download (look in the simutils > examples folder)…

Where should I start when I want to stack all the images into a 3d model? Is there any good example that shows how to do this?

Simple question that shows that im missing something. Plugging in the raw f and k valuse based on Pearson’s parameterization I end up with diferent results.
For instance if I use gs.setCoefficients(0.046,0.061,0.095,0.03);
based on http://mrob.com/pub/comp/xmorphia/F460/F460-k610.html
I get black. I asume it needs to be tweaked inthe last 2 values but im not sure how to get a 1:1 appearance.

Thanks!
