Random optics stuff
Posted: Mon Jul 08, 2019 6:39 pm
Time to open a WIP collection for myself, to keep sharing more stuff I try...
Today I couldn't help but procrastinate , 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 some DSLR lens, put it in Blender as a background image and model the lenses on top in ortho view. I picked the Zeiss Otus 55mm lens, which has a total of 12 elements, or 24 specular surfaces. Then, as usual, the detector as a thin slab of matte translucent and an aperture at the front.
Of course, the refractive indices are just coarsely guessed, and I only assumed two glass types - which is probably wrong, as is the location of the aperture at the front of the lens.
Finally, after a bit of fiddling around, I managed to get a nice result. The following was only 1 minute render time with Hybrid PathCPU:
EDIT: And that is even 1 minute on my notebook (i7-4800MQ)
