This one was bad at measuring.
The macro bend attenuates the light around 3dB.

#Scientists have demonstrated #quantum #teleportation over the #Internet for the first time

It may not be teleportation like you see in the movies, but it's real. Scientists at Northwestern University have successfully demonstrated, for the first time, quantum teleportation via #fibre #optic cables carrying internet traffic.

I set the #lenses quite well, with the maximum focus values, creating a sensor for each but I would need to see real photos as a reference to make comparisons, almost all lenses tend to blur images near the edges of the #lens.

The first macro #lens, this #optical group, has a high working range from near to far, and works well even with a low F/Stop.#optic #3d #Blender #b3d #Blender

It would be great if I found a way to use a #3D mesh F/Stop, on the left a 3D F/Stop on the right the #Blender one, both with f/stop at 8 the 3D one is approximate. But I have to increase the light and samples, but it seems to work #b3d #optic #lens

A bit dirty one, now seem more photo realistic, but it still need some more textures in too clean parts. #b3d #Blender #Blender3D #optic #lenses

After a long time I start to see the results, it's a shame that with path tracing rendering engines, it is not possible to have small #photographic objectives. #b3d #Blender3D #Blender #3D #optic #lens

I've update whole objectives assembly with new Ray Portal as a Camera's sensor, this change improved a little bit even the rendering time. first row #Zeiss Tessar, and second Row H. #Zollner #Tessar, both with new Sensor. Now I would need a bit of experience with photography to do better, some example photos with these lenses and a bit of technique would help me improve further. #optic #lenses #3d #B3D #Blender3d #Blender

I don't know what I did but now with the ray portal I can visualize a strange phenomenon of light rays passing through the various #optic #lenses of the objective assembly,but I compromised the previous node which I can no longer reproduce.😅😢 #b3d #Blender3D #Blender

Today after random attempts, because in reality I still haven't fully understood how it works, I implemented a Ray Portal as a sensor, and this with random values ​​allowed me to correct the angle and expand the field of vision of the lenses, previously some were too narrow and to frame the whole scene you have to move the camera a few kilometers away. Same camera with Ray portal and not and the difference is evident. #optic #blender3d #Blender #lens

I have made a simple video which highlights the differences between rendering with or without chromatic aberration. this method is better than #Blender composting that deform the images. and with #3D #lenses there are not diffraction changes. #b3d #Blender3d #optic

Tomorrow I will try to finish this old Pixar scene, and I will try to do some rendering test with some of the 3D lenses I created, but already from these tests without doing much, I would say that the difference is noticeable. :) #b3d #Blender #Blender3D #optic #lens #3d

Heck in the end the best of all is the simple one, I tried all the known dispersion methods, lots of nodes, but the one that comes closest to the photos is to use three different IORs with 3 diffraction materials red green and blue. #b3d #Blender #Blender3D #optic #lens #3D

Now the dispersion is better, I will look for a way to implement the chromatic aberration of the #lenses using the actual values ​​for the lenses, but it will not be easy, to do it, I have to find a solution for the brightness. #3D #optic #b3d #Blender3D #Cycles

I'm doing some checks by comparing the 3D #optical #lenses, but it seems to me that #Blender's f-Stop values, in addition to having scale problems, in this case the model of the Fiat 500 is in meters and OK, however #b3d's camera it has an incorrect F-Stop value. Left side b3d all with f/Stop is 0.2, others with 3D lenses are more realistic one with f/Stop at 8 and other to 18.0 Camera 35mm and 100mm #optic #lens #photo #3d

I found an interesting web about Paul Rudolph and his #optic #lenses design, one of the pioneer of #photographic objectives. I want to make those patents https://zeissikonveb.de/start/geschichte/personen/paul-rudolph.html

The best add-on for #optic lenses is #LensSim, it's fantastic, as well as already having many preset lenses you can insert and save other cameras with real data, today I inserted a new lens into the database, Lens Sim is incredible. #b3d #Blender3D #Blender

This is a video that shows the latest #optic #lens I created, and it is one of my favorite ones, the modeling was done with the help of geometry nodes which allowed me to precisely transfer the data taken from the original Patent by #Kodak (1941). #b3d #Blender #Blender3D

There must be something that doesn't work the way I imagine it should work. I've used various lenses, with different curvatures of the glass and types of lenses, they all seem the same, the focus distances and positions are different. #b3d #Blender #Blender3D #optic #lens

These are the results of my experiment in the #optical #lenses simulation with #Blender, some of them seems very similar, but now all free from defects on every lenses. I just understood also every lens in a rig can have his IOR. #b3d #Blender3D #optic

I've solved the defect in the #lenses on center, now I will also try to see if I can improve the method, which at the moment is not very precise, in fact making an arc on three points sometimes has the centers moved, probably a #Blender's precision issue and Geo nodes #b3d #optic

Damn it was all Optix's fault, with CUDA and CPU, the results are more reliable.. I didn't understand why, now I can try to make other physical reproductions of lenses. I found a starting point. #optic #lens #b3d #Blender #Blender3D
