Pleasenote that this is not necessary for the denoiser. It actually prefers half data input.

Means your denoising algorithm should be faster overall when keeping the data in half format because that halves the memory size and therefore required memory bandwidth and saves the conversion time


Another thing to try is switching from the HDR denoiser to the AOV denoiser with just the noisy beauty image.

The programming guide explains the differences (use of optixDenoiserComputeAverageColor function and hdrAverageColor field).



Technically I can split the image into 2048x2048 tiles as a workaround, but it would be nice if it worked out of the box or at least failed with some error code. My implementation attempts splitting the image if the denoiser fails.


Sounds good. So one last tidbit, you are manually splitting your image into tiles, is that correct? Just in case this applies to you, one thing to be aware of is that correct tiling with the denoiser needs to have an overlap region between tiles, otherwise you might get seam artifacts at the tile edges. Currently the overlap region is 64 pixels, but the OptiX 7 API has explicit calls to determine the overlap size should it change in the future, and the OptiX 6 internal tiling handles this overlap region for you.


Hello all, any IPVM members have recent or updated information on Network Optix Nx Witness VMS application and their NX2 and NX3 appliances? The latest user experiences etc.. on the forum dates back to 2013.


Joel, we have numerous installations of DW Spectrum, but have never used Nx or DW hardware. We just use OTS hardware, usually Lenovo or Dell servers, so I can't help you much with the Nx hardware. We were intrigued by the new Nx1 Micro Hive Server, but it isn't available to us here in the USA and we haven't seen DW offer it either.


As far as the VMS, it has really come a long way in the last few years. They are always adding new features. Since they rewrote the whole thing in 2.3, there have been major additional features. We are waiting for the new mobile app to be released on the DW side.


If we were to have any complaints, it is the fact that Nx decided to use DW exclusively here in the USA, which slows the release of new Nx versions. Well, and the fact that DW chose to use orange instead of blue in the UI. =)


Feel free to reach out to us directly with any questions as well. We're always happy to talk with new users to answer any questions you may have about the platform, hardware, or business. My email address is tl...@networkoptix.com


Always pleasantly surprised when highlighting an object with the 'smart search' the movement timeline instantly showing the movement of that item in red checkmarks in whichever zoom timescale your on, even months.


Great to hear! Let us know if you have any difficulties you'd like to see addressed in our software as well - we're always looking for front-line feedback from integrators and users and any pain points they are experiencing.


I have been reading about all the starbursts and flickering and poor support for these expensive multi focal lenses used for cataract repair. I am really disappointed that I still have astigmatism and need glasses after spending an extra $5000 for these high tech Alcon Panoptix lenses. If you are like me, you want to be heard. Panoptix has a web page with a contact function for "feedback." Use it! I am resentful that they present misleading satisfaction surveys. Obviously their design folk focus on fun technology and not on customer satisfaction. And their designs don't seem overly robust. So many ways the surgeon can screw up. Who wants more surgery to correct toric problems or to get a new lens? We need to tell Alcon, and maybe the FDA, exactly what is wrong. It is totally ridiculous that starbursts last forever or flickering is just to be ignored. Sigh. I so feel tricked. The statistics given are misleading. These are our eyes, not a new dishwasher. Can't be replaced. We don't want successive surgeries or a lifetime of corrosive eye drops. This is a product that has been over sold. And eye surgeons don't really seem to offer good advice or solutions. I was told to ignore the problems. "Maybe they will go away." Very sad. Might be smart to share our experience and prevent a lifetime of problems for those who haven't yet had their inevitable cataract surgeries.


l'm having cataract surgery this year, l suggested panoptix to my surgeon , he said l should go with Vivity EDOF instead, he said my reading or near vision wont be as good with vivity but theres alot less side effects


l went with vivity in my first eye a few days ago and second eye in a month, so far l love it, l have great vision near, intermediate and distance, my surgeon warned me against panoptix and said to go with vivity,


It has been almost 3 months since I had the Panoptix lens implanted. I am having extremely poor night vision in that eye -- multiple rings and lots of flare. It is happening during the day now too. In bright sunlight the railroad crossing signs or anything reflective look like rainbows. Just last night developed a new problem. I originally thought it was a huge floater, but it is not, it doesn't float, it moves in unison with my eye. The doctor has given me a .75 contact, but it didn't change the night vision at all and did only some to correct the near and mid-range blurriness. He also suggested lasik to repair the eye, but I am wondering if I shouldn't just have the lens replaced, because I don't know what my options will be for replacing the lens after lasik. Going to call now and see if I can get an appointment to find out about the new problem and ask that question. Thanks for the info on the Panoptix feedback.


A "floater" that moves as fast as the eye moves sounds like posterior vitreous detachment (PVD). It can happen due to simply age but is more common after cataract surgery. I got it in one eye 10 months after surgery. The procedure to get rid of it, is ugly and not worth the risk. They keep telling me it will go away by itself....


They told me it was a Weiss Ring as you said from PVD, and that hopefully gravity will pull it downward and that it would eventually go away. Or that my brain would stop noticing it. It is tolerable when looking forward, but for activities like Pickleball it is really bothersome. I will definitely not get a Panoptix lens in my dominant eye. I would be effectively blind at night if I did. The rings and glare are so bad with the Panoptix lens, I know it is not right for me. If anyone had told me that 1 in 10 experience the really bad side effects that would keep me from ever driving at night, there is no way I would have chosen this lens. They plan to do Lasik to correct the near vision in the eye with the Panoptix lens at the end of April after I get the Truline lens in the dominant eye in mid April. I will post the results of one eye with Truline and one eye with Panoptix and the Lasik after they have some time to heal and I can adjust.


Yes, mine originally looked like a solitaire engagement ring without a stone, and I could see it in 3D depending on which way I looked. I could see it flat with the whole ring showing, or at more and more of an angle. When driving if I resist looking at it, the thing stays kind of on the right shoulder of the road. But, that can be hard to do unless you can get it out of your mind. I also see it when using a computer with a window which has a white background. If you focus on the text it kind of goes away. I was given the same story about it falling down to the bottom of my eye. I kind of think that is mainly to put you off until the next appointment. If gravity makes it drop to the bottom of my eye what does it do at night when I am lying down? Will the ring critter climb back up again??? In any case over the past 6 months or so it has gotten a little less distinct. I have to try much harder to see the ring and mount image. But, it is still there unfortunately, and has not sunk out of sight!


I had not heard of the B&L Truline lens. Are you aware that is an old lens from about 2013 or so? I don't know much about these MF lenses other than from what I see people here talking about. You are the first one that has mentioned this one from my recollection. The PanOptix is much newer from about 2020 or so, and the J&J Synergy is newer still from about 2021. There is a good chance that the Truline could have the same issues as the PanOptix or worse. You may want to start a new thread to get opinions about it, or do a search here. It could be a jump from the frying pan to the fire choice...


I am basically done now with a monofocal in both eyes in a monovision configuration. I have no regrets. I think there is an option however to use a distance set monofocal in the dominant eye, and a MF or EDOF in the non dominant eye. I might lean more toward that choice.


Rereading your posts, I think I would consider getting a Clareon monofocal in your dominant eye set for distance (-0.25 D target), and leaving the PanOptix in your non-dominant eye for now. Then you could see if that works out for you at night. The better night vision from the Clareon monofocal may help you ignore the flare/halos from the PanOptix. If that does not work out, then you could consider an exchange on the PanOptix. It could be simple monovision with another Clareon but targeted for -1.5 D myopia, or a Vivity targeted for -1.0 D myopia.


I believe the Trulign is the toric version of the Crystalens. The Crystalens doesn't have diffractive rings like a multifocal so it shouldn't have halos but the consensus is that it doesn't actually work for presbyopia. This lens has largely fallen out of favour and very few surgeons still use it. It provides little if any accommodation (adjustable focus) and in some cases the hinged haptics have even bent in the wrong direction and/or the lens has become tilted due to it's novel haptic design. It's even been subject to recalls. And there have been lawsuits. I would not choose this lens and to be honest if any surgeon even recommended this lens to me I would find another surgeon. I'm surprised B&L is even still allowed to sell it after all the problems with it. I would use an Alcon Vivity or Alcon Monofocal in the second eye (in the Clareon material if available where you live).
