Diffraction?

Postby zeealpal » Fri Aug 12, 2011 7:52 am

I am doing Yr 12 Physics (Australia) and we are currently studying light, and I have noticed and tested (out of curiosity) LuxRender for Refraction, Dispersion, Diffusion (colour bleeding etc), Reflection, Scattering (I think)

But I have not been able to replicate a successful test of diffraction. Can LuxRender simulate Diffraction?

Here is my test scene, 2 paralleled spotlights shining on 100% Matte Black Planes with a tiny distance between them (Young's Slits experiment) onto a white plane.

I was just curious if this is done by LuxRender, of if any other renderer can do this.

Edit: This is waht I meant incase I wrote it badly. http://en.wikipedia.org/wiki/Double-slit_experiment

Diffraction requires lightwave simulation. This part of the wave–particle duality isn't implemented in any production renderer i'm aware of. Raytracers are called that for a reason. I guess there is little demand for such low-level effects outside of academia.

Thanks :) I guess that makes sense, no point wasting speed for such a little thing :)

Hi,

The only diffraction commonly implemented in production renderes (but not yet in LuxRender) is eye lashes diffraction or aperture diffraction (their is glare simulation for that part). General purpose diffraction is way too complicated to simulate in general.
