I'm whipping up a set of notes, and I want to include a diagram or two showing some partial derivatives. Specifically, a diagram would include: a 3D surface of the form z=f(x,y), a plane of the form ...
Please recommend a program that can build a graphic of a 3d function and save it to some vector file format (SVG, EPS/PostScript, WMF etc.) I found only Madagascar software, it is free, but it was ...
Given N, 3D position vectors, I want to find the best-fit plane of those vectors. I found a suggested answer here that said: Calculate the average of the points (easy) Calculate the Covariance ...
What are some examples of software or online services that can display surfaces that are defined implicitly (for example, the sphere $x^2 + y^2 + z^2 = 1$)? Please add an example of usage (if not ...
I am looking for (preferably free) software to: 1) plot 3d points read from a file. A scatter plot would be fine. 2) Optionally color the points by a property - also read from the file It would be ...
