Re: Random optics stuff

With no lens formula it's hard to get the lens in focus. I played little with the Zeiss ZM 35mm 1.4 Distagon design, but the Meyer Optik Görlitz Trioplan looks interesting. It's a 3 element lens with soap bubble bokeh like below: Indeed, the exact curvatures are very important :) Fortunately, you c...

Re: Artifacts with hybrid/bidir/light paths

Ok I relaize I had some wrong thoughts earlier, plus some info missing: - I thought of the Suzanne head as intersectable, but it is not an emitter itself. However, it is matte, so you can connect to the Sun from there. -Also, there is a "detector" behind the lens, the usual matte-translucent slab. S...

Artifacts with hybrid/bidir/light paths

I have been trying to do more modelling of lens systems, this time with a simple Cooke Triplet. blend-file attached. In my scene I only have a 5 cubes with emission (they produce some defocus circles), and a Suzanne model illuminated by a Sun lamp. With these being intersectable sources, rendering w...

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

A nice set of features, if you ask me, but again I have no idea about computation cost or implementation complexity, let alone how many users could be interested. Don't get me wrong, I don't believe either that it will be worth the effort to implement all this. :D I've been trying to get lens flare...

Re: Disable self shadow?

Is there a feature like in another rendering engine/software that you are referring to? I think I know what you mena, but I'm trying to think if this is even possible to define in a general case... :?:

Random optics stuff

Time to open a WIP collection for myself, to keep sharing more stuff I try... Today I couldn't help but procrastinate :D , so I decided to test the boundaries of working with complex lens systems in LuxCore, and to try how easy the lens addon is to use. So, I searched for an image of the design of s...

Re: Little Addon for optical lenses etc.

Finally had some time to continue. First addition: Material textbox as suggested by B.Y.O.B. (thanks!) together with checkboxes for smooth shading and adding an edge-split modifier. The material must be pre-defined on some dummy object. It does not work to create a lens/mirror, add a material to it,...

Re: Different Works in Progress

Oh my it took me ages to understand exactly what is what in this image and how it corresponds to the scene objects :lol: :roll:

Nice to see the addon is being used :) I'll have to expand it a bit more soon, could use some extra features myself...

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

I think I'm a bit losing your point... Are you suggesting that raytracers should move towards the simulation of real camera systems, with real lenses and sensors? Wouldn't this be computationally a lot more expensive? The "thin lens" camera model has limitations for sure, but is very effective. As ...

Re: playing with caustics

Looks good :)

Did you compute the water with a fluid simulation or a plane + dymanic paint? (Or something else...)
