wire/thickness

Support Compositing and Post Processing

hi
well i’m quite new to Blender…
but I tend to use mesh topology to show stuff for many things
so i have 2 issues

  1. i can render mesh as a wireframe but how can i change the thickness of the the wire?
  2. what’s the best way to convert meshes to edges and how to visuaulize them?

I don’t use the wire material, actually. What I do is duplicate my mesh, and delete all the faces , and the edges except for those I want to show. There’s a python script bundled (under meshes) called “edges to curve.” This will convert all lone edges (those not attached to a face) into a curve object. You can then add thickness by adding a bevel curve (BevOb) or a simple Bevel Depth.
The only problem with this method is you run into kinks when the curve goes past vertical. Sometimes this can be ignored, other times you can minimize or remove it by carefully picking your edges and rotating in edit mode.

i tried that…
but i was looking for more fast-forward approach
maybe something like a ‘lattice’ modifier in 3ds or similar

Hope this helps you ^^

EDIT: D’uh, I just realized the link I provided there seems to be dead…now, maybe someone can provide the script? I personally should have it as well but I didn’t find it. There’s also a script called “Solidify selected egdes” in Scripts -> Mesh which should do the trick, too, but I didn’t get it to work now. Sorry, seems like I can’t really help you then =/

it helps but not much
thanx anyways

If you render as wireframe, use Edge and EdgeSettings in F10. Set the Eint value higher for thicker edges.

%<

yea this looks better now
but i can’t make the wire really thick
looks like the Eint value doesn’t reflect the whole range from 0-255

This may help:

“Rendering Solid Wireframes”

looks good
i go into it…

believe it or not - if you turn ztransp on, you are able to control the wireframe thickness with the materials alpha slider.

wheird - anybody knows why?

Change your OSA type and filter size (on the render pannel directly underneath the “Fields” button), then see what happens. Next, try turning specular reflection (Spec slider) and diffuse reflection (Ref slider) all the way down and experiment with the different variations of each. That may give you a clue. BTW, that is a good thing to know. Thanx for posting it.

there is a script to make a real wireframe (with vertices and faces) from a given mesh. I found it somewhere, you can grab it here, but I don’t know where I found it anymore:

http://www.ontheserver.de/temp/Blender/tesselate8_8k.py

copy it into {blender directory}/.blender/scripts/ and then run it by entering the scripts window/scripts/misc
