2016-06-26 19:00:36 +0100 | asked a question | Customizing the wireframe / strides of a 3D plot I am experimenting with 3D plotting to see how I can customize the output. In particular, I am trying to obtain something more similar to how Mathematica or Wolfram Alpha do things. For example, I plotted Taubin's heart surface: $$ \left(x^2+\frac{9 y^2}{4} + z^2 - 1\right)^3-x^2 z^3 - \frac{9 y^2 z^3}{80} = 0 $$ Using the following code: The mesh corresponds to the triangulation of points that Sage performs on the data calculated with What I think they are doing is they are using a high number of points to draw the surface, however they are "slicing" the object with planes parallel to the three axes (at fixed distances) to draw the contours. How can I replicate these lines? Matplotlib calls them "strides" as documented for In this case the presence of too much grid lines looks even worse: |
