View Full Version : Splines to tubes?

I swear I remember at some point they added a feature that you could render a spline as a shaded tube. You just set a thickness to it. Am I crazy? I've been searching and searching, but I can't find anything so I think I must be nuts.

2 point polys not splines I think.

It's true the splines don't render and the 2 point polys do when using the 'edge' features in layout found under object properties, but still no shading.

put -10 in edge thickness they won't have perspective, it's a screen related size.

ah yes, that's what I was thinking. thanks Probiner. Too bad abou the screen size limitation!

it is, IT would save alot of memory for many types of materials made of visible mesh/thread. Instead of having polygons loaded in layout, you would have only 2-point-polys, way more memory friendly while you can push to better results.

From another thread:

I don't know how hard it would be for Newtek to add a 'T' for Texture there. And this way with a gradient, one could make the size change :D
Matt? =P

Win only and $300. :(

Thanks for the suggestions though!

I just did a bunch of rail extrudes. Nothing like the brute force way. :D

Px_bezier plugin will automaticly create polychains, set your polygon type to line, you could draw straigh or curved polylines.
works with glows and fiber fx and more.


You could also active strand maker in modeler to convert curves, but nicer to get exact divisions with px_bezier.

Thats nothing, I have both plugins and I still use rail extrude and realize later I could have used one of the plugins.

Have a look on the LightWave Plugin database.

Hope it's of use :)

There also used to be a trick, (think Proton made it known), set the thickness of 2-pt polys to a negative value and they become thick like a pipe but there are limits to that effect, think they don't behave properly with shadows if I recall correctly.

Shame that Truss 2 doesn't work with 2-point-polys tris and up. Nice results it shows. Thanks to Dana Burman for the youtube video.

But, If it's going to be based on polygons I might prefer this way, specially if I need the geometry to be connected or transparent.
