Hi there, Is there a decent way of plotting a give coordinate curve for a parametrized surface, except explicitly writting its parametrization as a path3? I mean something like f(s0,t) (f being a triple or a real valued function), for some fixed s0. Also can one have tangent lines to curves at a given point (without finding their equation on paper and drawing the segment through two points)? Thanks in advance and best regards, Alexandre

Hi, John. Thanks for the very prompt answer. Your example uses opacity. In order to handle opacity correctly, you need SSBOs, which require OpenGL 4.3 (available since 2013). You should upgrade your libraries (or settings, as you have shown) to use the latest OpenGL drivers. I had no clue on what is SSBO, but at least the acronym meaning is clear now. ;) I just did a reportbug to Debian on that issue. Even on more recent machines the version is 3.3. Let's see what they say. It's not recommended to...

Hi there, This post is not only about PDF, but since this topic is here, I think it is better to use it to avoid duplication and making information sparse. On short: asymptote can't produce "flat" (PDF or PNG) output while HTML 3D models output work pretty well. I have a Debian testing installation here, with the following info given by asymptote: $ asy --version Asymptote version 2.82 [(C) 2004 Andy Hammerlindl, John C.
