13 Dec 2013 geom3d Library to handle 3D geometric primitives: create, intersect, display, and make basic computations Author: David Legland

After some minor initial tweaking, I find this a very helpful mission. Despite its size all parts seem to work seamlessly together. Thanks David.

With all respect for this valuable submission. I do have some slight critique. I downloaded geom3d to "quickly" check against my code for the determination of the spherical angle, as the function "sphericalAngle" promised. I only called sphericalAngle exactly as indicated in its help. I ended up wasting two hours of quality time ploughing through various fixes. [1] calls to functions whose names have been changed. Sorry , but I just stopped keeping track(some have already been mentioned in these comments) and [2] createPlane, was called from within sphericalAngle apparently with the wrong dimensions. [3] intersectLinePlane complained about matrix dimension mismatch on line 71. Honestly, I consider perseverance one of my strenghts, but I gave up at this point, as I can't say how much more time this really simple operation would/should cost me should I continue with geom3d. Sorry, but a smooth program flow is really important, especially in extensive code submissions such as this one.

I downloaded the code and it worked in the first run without any problem. After playing a little bit with the parameters I obtained a 3D flow that allowed me to create a very nice segmentation of 3D time-lapse microscopy image with fluorescently label nuclei.
