[Feature Request] 3D surface/contour/line plotting?

[estysdesu]

What is the feature ?

Support for 3D plots (lines, contours, surfaces).

(Optional) Why this feature is useful and how people would use the feature ?

Many mature plotting libraries provide support for plotting 3D shapes (lines, contours, surfaces).

• igiagkiozis/plotly, which is bindings for the plotly.js library, supports 3D lines and surfaces.
• siegelord/rustgnuplot supports 3D contours and surfaces.

Now, I understand these libraries are actually just bindings for plotting libraries written in other languages, but 38/plotters is the only library (that I have found so far) that natively supports the EvCxR Jupyter Kernel. 3D plotting is one thing I think most people expect from a mature plotting library (at least in the data science realm). I'm aware, that 38/plotters is technically a drawing library vs a plotting library. But, even an example of how to generate a 3D plot would be a nice springboard.

Thoughts?

Hi there, thank for using Plotters. You have already realized that the plotters is more like a drawing library vs plotting library. Unfortunately the low level drawing API only support for 2D drawing and 3D drawing is on my backlog for a long time.

For the roadmap of the 3D plots, I am going to support CPU 3D rendering first which I am planning to support it after the next major release which is happening in this or next month. For hardware accelerated rendering, it will take a longer time.

Cheers!

Supported in v0.3
