I’m new to Rhino, and rendering in general.
My goal is to render a red/green laser beam hitting a glass-air interface, resulting in a diffuse scattering. I don’t care about the transmitted beam — what I’m looking for is a diffuse elliptical “spot”.
The effect I want is similar to a laser pointer hitting a pane of frosted glass, except that the glass itself is clear. I want the laser itself and the surface it touches to glow like a lightsaber.
It’s just a laser pointer bouncing off a window very obliquely.
Getting a realistic laser beam is proving challenging. I have an X% transparent green beam rendered as a very fine cylinder and casting no shadow, but this is a bit average.
Getting a surface to be “emissive” such that a translucent object held close to it will be illuminated brightly, but objects further away will scatter less light.
Anyone have any pointers on how to deal with this, or a link to someplace where it is discussed?
