Another idea is code that "follows the contour" using the gradient of > the function.
Years ago, Steve, my colleague, wrote up such an algorithm for Mathematica. I believe it was part of one on of the standard packages at that time. But it sounds like if you/they already have code, so it probably would > be easiest to just convert it into the library function. We have code for 2d implicit functions (it likely needs work). We want to implement for 3d implicit functions.
