Metaballs.... What about lines 2005-04-12 - By Raffaele "ThE_JacO" Fragapane

The problem is that that thing is incredibly heavy and will also add to the
scene data.
The first comparison coming to mind are hair primitives, how much more
effective they are then generating the same stuff with pure geometry in your
scene.
Differences in rendering times and adaptivity, between meshes and rendertime
curves, are also relevant.
Last but not least access in the rendertree to lines as shadable entities
would SERIOUSLY help in some situations.
If you never had a chance, a couple of days playing with the way Houdini
manages this would literally blow you away
Said that I haven't needed them so badly yet, not in any of the projects
I've taken on over the last few years, but I'm sure if one of these days I'd
need them I'd probably resent not having ever mentioned the issue.
Actually, as a temporary patch, Just being able to generate and control
single hairs with no segment limits from curves (and no requirement for 3
curves) would go a long way, and it would let you shade them a fair bit with
vector states.
P.S.
Not addressing you in particular Guillame, it's great that you're being
constructive.
I was just randomly blabbering at the issue because I'm bored and waiting
for the farm to chew on some stuff.

Subject: Re: Metaballs.... What about lines
I don't know C4D rendered curves but the 3ds max "rendered lines" looks like
some extrusions along curve in XSI...
So here is a possible workaround :
- Create a circle to control the thickness/subdivision of the "rendered
lines" then select all the curves you want to render.
- Run this script
http://www.philbarrenger.com/tutorials/beggin-script/begginerscripttut.js
- Pick the circle et voil�.
Curves are not lofted at render time but it can do the job.
