Greetings M-porters - what is your biggest model?

Hello from Vancouver

The 'official' caveats about the technology limits of 200 scans and 10,000sqft with the guidance relating to bandwidth and tablet memory leave me concerned.

I have recently had two projects going over 100 scans. The last was a tight complex architecture and all the cobditions that drive up scan count** but only 2100 sq ft.

** cluttered furniture, multi stair cases, mirrored passages ... lots to create holes and shadows

Has anyone gone over the limits and are you willing to share how big, what did you encounter, techniques and your technology capacities?

  • Hi Simon,

    My largest so far is the Palace of Fine Arts that covers an area of 100,000 sf and has a little over a quarter mile of 'walking' distance. The final model has 275 scans, but it took over 500 scans to complete for alignment due to it being a totally exterior shot. You can look at my posting on this under 'How I Did It' section of this forum. Even then there are some 'wormholes' effects with it

  • Hi Bill

    First! Thank you for taking the time to describe how you did it but thank you too for replying to my question. Cool presentation; great subject!

    Please advise what your technical environment consists; tablet memory, bandwidth et al.

    How long did the model take to process and did you have any error-failures during upload or processing? For clarity did you need to delete scans pre upload (not to correct alignment) but to bring down size? I am assuming you used 'hide' post upload processing to make navigation simple?

  • As I recall, processing time was a little longer than a 'standard' shot but not abnormal. (I have had a couple very large projects take up to 48 hours - but that is very rare) It processed fine with no errors.

    I did not delete any scans to bring down the size. While MP supports up to 200 scan points, you can process well over that size (300+). I did hide some of the scan points in Workshop for the navigation. I currently use an iPad Air2.

  • Thank you again Bill!

    I will continue to probe the community, in the main thread, to get some insight into the cautions provided with the maximums by MP and in particular the memory / bandwidth advisory.

  • ALL Bills input is invaluable!

    What about you - do you have experiences on reaching limits BUT HAVING exceeded the 10,000 sq ft and 200 scan warning? Commentary that advises tablet memory and your internet speed / bandwidth would be appreciated.

  • Right now a customer is asking me for a job that involves 40.000 m2 (about 431K sqf) for a container warehouse he owns... is this possible?

  • Hi Bill - It sure seems like you tested the limits with the Palace of Fine Arts. So are you saying the caveat limitation of 200 scans 10000 sq. ft. is just a function of what memory you have in your iPad? Did you do over 200 scans all in one upload? Or did you scan portions, upload the model and then came back to scan and upload more portions as you went?

  • @simonmodera I just completed a 36,600 sq. ft. model of a film production office [broken into about a 4,000 sq. ft. and a ~32,600 sq. ft.] The larger is under 500 scan points. I had numerous issues with misalignments but it's because of the symmetry of the space not the number of scans or the size of the space. I earned my stripes on this one! @Bill is just amazing 100,000 sf is mind-blowing!!

  • Hi @simonmodera,

    This is a really great question/concern and as you can see many sites exceeding the stated limitations have been scanned successfully.

    The 200 scan and 10K sqft limitations are primarily what we guarantee to work and, most importantly, process on our end. The ability to process a model depends on more than just the total number of scans and 360° Views. For that reason, we can only guarantee 200, but certainly have been able to process scans much larger in the past.

    The number of scans you can capture depends on your iPad. Older iPads will start to fail after a couple hundred scans, while new iPads will be able to capture several hundred without a problem. The benefit to capturing everything in a single model is you can at least try to upload and process it into a single Space or you can break it up into multiple models to be processed into smaller Spaces. Keep in mind that even if it got through processing, visitors still have to see the model and some are using old computers.

    I suggest, if the Space is too big, to break it up into multiple Spaces. Here's an example I love to share. It's 3 Spaces linked using a fancy image map.

    I hope that helps :)

  • Hi @Matterport-Amir. THAT. IS. AMAZING! Please advise how we can reproduce this - its the equivalent of an interactive floorplan - Please advise how we can do this ourselves - is there a 3rd party service and or special software to create the MAP and How doe you embed that into Showcase?

  • @simonmodera @Matterport-Sibyl Thanks for asking. Here is the larger model: http://fivedmedia.com/3d-model/cnm-ingenuity-film-production-office-2/skinned/

    Here is the little rascal: http://fivedmedia.com/3d-model/cnm-ingenuity-film-production-office/skinned/
    The most amazing thing happened a few days after submitting to them. They sent this is an email "Thank you for the work you accomplished at 1008 Coal – it’s excellent." AND asked a bid on scanning one of their buildings (Jeannette Stromberg Building on the main campus) with 4 floors each approximately 40,000 square feet is what I've been told.. Looking at floor plans now.

    The models (listed above) are of a Film Production Office that the school rents to film crews. This is a VERY OLD Warehouse that was once used as a money counting location for Wells Fargo. The building was renovated in the 1980s.. It's not glamorous, but is perfect for setting up sets for filming movies/tv shows.

  • Hi @simonmodera, They did an amazing job and it's a great example of how different Spaces can be linked together in a very creative way. I don't know exactly how they did it, but have a pretty good idea. They did go above and beyond with their image map to make it expand like that, but basically it's all done in HTML, CSS and the expanding/contacting of the image map is Javascript. The HTML and CSS, I can suggest a path to get you started, but the Javascript may require a developer or just find the code online. There are tons of coding resources online that can tell you exactly how to do it.

  • Yes please and thank you Amir! I was hoping Matterport would enable this - In some cases I would use the floor plan to create an interactive floor plan using a conventional 2D floorplan uploaded (a frequent ask ). In other cases it would be a mega plan - like in your example to enable multiple model links.

  • About iPad capabilities that impact model sizes - 3 key factors but not only these

    Storage a.k.a 'space' 'capacity' e.g 64 Gb is how much data is held until deletion - is not really a determining factor for model size but does impact how many models you can keep

    RAM - Random Access Memory - temporary working space used by iOS and active applications. This is the key factor for 3D model size. Larger and more recent iPads tend to have more - see Wikipedia tables . e.g. An iPad Air has 1Gb while an iPad Air 2 has 2Gb - i.e. double. This is NOT storage

    Processor Architecture - Most iPad model upgrades have new CPU central processing unit - a.k.a. 'chip' and or GPU (graphics processing unit - a.k.a co-processors. The more recent are more capable of 'managing' larger models with more data points - 2 performance aspects

    Speed the iPad Air processes at 1.4 Ghz & the iPad Air 2 processes at 1.5 Ghz then (not taking into account graphics processors or bus speeds) it does the same tasks +-7% faster.

    No. of Processors - the 'dexterity' effect when handling tasks These handle touch inputs, screen image delivery and movement etc. iPad Air = 4 Core, iPad Air 2 = 8 Core @Bill @wayne

  • Ran out of space and deleted a key comment - Storage does not impact an individual model size presuming you have space to store the model.

  • What can an MSP do to influence. Buy the most capable iPad. Close all other open apps when running Capture. Limit communications interruptions (e.g. Wifi) to only the CP Camera i.e. dont allow email, messenger, other app notifications notificatiions.

  • Hi @Bill

    Now that we have clarified that the iPad model has a direct bearing on the Model / Space / Scan Count size we may need to also provide some cautionary advice about the impact of successfully large models on audience Showcase experience on older / smaller tablets.

    I had a client complain of tours crashing on iPad Mini 1 for a model with 121 scans and 11 x 360s. I verified that with a loaner iPad Mini 2. Both had pretty decent network speeds but probably inadequate RAM as the key factors would include RAM siz, Processor speeds and cloud connection speed / reliability.

    I have not had the client re-try yet as they were very disappointed that a 3year old device was inadequate. I believe (? @Matterport-Scott or @Matterport-Amir please correct me if I am wrong) that there has been some work done by the Development team circa September / October 2016 to address the 'streaming' that may have helped.

    Have you (anybody) had any complaints about your large model tours crashing?

  • Hi @simonmodera,

    Yes, there was a 3D Showcase for iOS update that addressed large files crashing, and while the problem was very much improved, there are still some reports of large Spaces having issues.

  • Omg Lisa Hinson! How did they do this?? http://www.ticketyview.com/twc

    That's amazing!

     

    What software they are using?

    Thanks!

  • This one I really enjoyed but only had a limited time to complete (8pm - 1:30am) 17,836 sq ft ... Would have liked having more time to completely fill in the Dollhouse.  I was scrambling to wrap up with the time constraints.  Look at this beautiful video made with the OBJ file though...  https://vimeo.com/213671653
