This was touched on here:
I am trying to make what amounts to a 3d mind mappijg program, but in reality is a multi-data type conceptual mapping took bringing together authors, citations, keywords, Geographic location (as well as time) etc. The idea is a big project, but it would be skimmed way way way down for a proof of concept.
Question: There are times where i would like to use render.drawline, and other times I would like that line to be a bezier curve. Is there anyway to do this without the curve being a mesh object (imagine having a thousand?) Should the same be done with straight lines?
