LED Lighting in renderers

Stijn · 03-01-2007

I have been looking for a solution, but with no success...
How would you guys visualise LED lighting in a rendering? And then I mean of the kind you can see in the attached pdf. It are strings, for the corners of a floor.

I use 3D Max, preferable with Vray, but if any other system within Max proves better for this, I'd like to test that too.

I don't think it's not too difficult to replicate in 3ds and I'd be looking at a Glow shader is Mental Ray for a start. There must be something similar in Vray and I seem to remember you can apply some kind of lighting shader to any primitive in that renderer. Anyway your answer is probably shader related so dig around and see what's close.
I've attached a quick image that I did in about 5 minutes. There are no lights in the scene so if you play around I think you can easily replicate the effect you're after

Could it be possible to give the me stats of that?...

Here's a better image for you.
The helical tube is a lofted circle to which I applied a mental ray material. The surface was mapped with the Glow shader and the material set to Glass, which gave the white semi opaque colour. If you look at the various slots in the material editor for the mr material, you'll see where things go.
Spheres are place 'inside' the tube and another glow shader applied as above but with a higher brightness.
3 omni lights were placed around the outside of the tube and from the rendering menu select Effects/Add/Lens Effects/Glow and select the lights.
This is probably a little hard to follow but it gives you the overall idea - if you experiment a little I'm sure you can come up with something better/faster/easier as this was just a quick grab bag of things that came to mind.
You can increase the brightness of the tube but this one is similar to those in the pdf once the lights are placed inside.
The important thing is to make sure the spheres are always brighter than the tube .

So these are actual object you made? I'll try what I can come up with.

Yes all made in 3ds max.
You can vary the intensity and colour in order to obtain a variety of effects as shown below.
