Total noob here.
My goal is to be able to create figures in the following style (source): with a workflow consisting of Blender and Inkscape. I'm sufficiently skilled with Inkscape, but I'd really like to get the mathematically defined shapes done to perfection in Blender.
Currently, my challenge is to draw the surfaces (open or closed) smoothly, but with grid lines. I'm using the Freestyle renderer with the SVG exporter addon.
I'm also using the addon for extra objects which includes meshes generated by equations of the coordinates.
I would like the nodes in the grid to be connected smoothly (i.e., I want the underlying mesh to have a higher number of samples than the selection of Freestyle edges). This might be as simple as me learning how to select ever 10th node in a row or something, but I don't have the Blender experience to make that a trivial task.
Any advice is appreciated.
