[Req] Dispersion Scene
[Req] Dispersion Scene
Godzilla posted a cool dispersion scene here:
http://www.indigorenderer.com/forum/vie ... 9&start=15
I am curious to know a few things about creating a nice dispersion scene. For example:
How do you create the beams of light?
What are the material settings for the prisms?
Any other tips for setting up the scene?
If you have created a nice dispersion scene, please share it (preferably in an editable format such as .blend) so we can learn from it. Thanks.

Re: [Req] Dispersion Scene
This is very simple.
Beam = a small light source inside a narrow closed space - one end closed, one open (like in the end of a tube or smth)
Prism material = specular glass with cauchy_b_coeff > 0 (larger values mean more saturated colors of spectrum)
That's it.

Re: [Req] Dispersion Scene
I am having more trouble creating this scene than I thought. I am not getting a nice rainbow effect. I have a prism that is about 2 inches across. Does the size of the prism matter? How big should the light source be? How big should the hole in the tube be? I have cauchy set at 0.003
Also, should the prism be sitting right on the ground or should there be a small gap (>0.2mm) between the ground and the prism?
Any other suggestions or tips? Could someone share a scene that works for them? Blender or SketchUp formats are welcome.

Here's my scene.
(Ono/Benn, could you please make it so we could put 3d files in our attachments?)

I'm so taking a loot at this Thanks God! ...zilla
@Godzilla: I thought you could just .zip it and it would upload fine?

Re: [Req] Dispersion Scene
It would be so much easier to just be able to upload it directly.

Re: [Req] Dispersion Scene
Thanks for the awesome scene godzilla! I want to use it in a SkIndigo tutorial to show how to set up a dispersion scene (if that's ok with you)
Here's the result out of SkIndigo:
The first time I rendered it, I used MNCR=5000. However, I got some fireflies so I re-rendered at MNCR=1000. Notice the difference?

Re: [Req] Dispersion Scene
A second rainbow is missing on the upper prism.
Now, what's the price?

Re: [Req] Dispersion Scene
Hello,
I'm fairly new to Indigo and I'm stuck at the lighting setup. There are several options to create emissions in Blender, and I don't succeed in creating a long narrow beam through 2 cubes emitting by a plane.
Could someone give me a hint?
Thanks in advance

@Godzilla
Your scene looks awesome. Could you tell what rendering mode and light setup you used?
Cause currently I'm using scenes I originally rendered with Luxrender to make sure the geometries are alright.
But somehow the scene is very dark, and Indigo renders much slower (BiDir) than Luxrender did(BiDir).
Greetings
