Re: Tiled OIDN Denoising

Some test images can be found here: https://owncloud.gwdg.de/index.php/s/mkgXCBpkoQF0Egz I only denoised the 16 sample image with OIDN v0.9 for comparison now. As I said before, the behaviour changed a bit, especially at low samples I noticed some color differences between 0.9 and 1.0 in this scene....

Re: Tiled OIDN Denoising

Ok, I downloaded it today and tried it out. Worked directly, so no broken dependencies or something (I didn't try Blender viewport denoise yet). The change in the code was as easy as I thought. From a first quick test on the LuxMarkHotel @4K and 20 samples, there is a visible difference between the ...

Re: Tiled OIDN Denoising

Their implementation of tiled denoising now exposes it with a "max. memory" input, which is nice so we can now directly expose it as a memory setting instead of number of pixels. I could give it a try later this week, should be easy enough to implement as far as I see it. Just need to rename the til...

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,...
