Can You LIDAR Scan a Movie Studio?

[@bennotoorn4782]

Great video and demo! I recommend to clean the noise in Recap before exporting it as a mesh. Hide the roof > select the floor plane > hide selection > Select everything inside > delete > unhide all > save as. Or using the automatic (cloud) cleanup tool. Cinema 4D looks like a great tool for visual planning and rendering scenes.

I wish the Leica was a bit cheaper ... been trying to convince our small company to buy one. We make all kind of metal structure/pipe work in industrial environment and in my humble opinion 3D scanning would drastically improve the planning portion of the workflow. Now we just go and measure stuff with measuring tapes and spirit levels... x(((( the amount of measuring errors and things not taken in consideration and all kind of time lost on figuring stuff out.. planning on a 3D sketch you could get all the measures automatically then and there. So friggin easy and precise..

[@DSP1337]

The scans like you've shown them look kind of noisy if this term can be applied here. Is there any way to smooth out the scanned footage some more? Like automatically filling all the "holes" in the point cloud or connecting them with the approximate texture? This might lower the overall texture resolution but could make for some pretty nice indoor simulations - e.g. for real estate "photography".

[@CinematographyDatabase]

Noise could be fixed by taking more scans. The point cloud shows what it captured. The meshing stage there is a lot you can do to "clean up" the model and reproject and or paint/touch up the texture

[@Veptis]

The Autodesk software. ReCap Pro in this case, has some tools for smoothing a scan and making it into a single solid model. You can download a trail and example data(even raw uncleaned data) or activate the software as student...

[@SKLGN]

dude, you are fucking crazy awesome! This is future of pre-production!

[@Patrick-jj5nh]

very interesting, could you combine this with a VR headset and then get a good impression of your setup as seen through your eyes to scale?

[@CinematographyDatabase]

Yes, you could bring the final model into Unreal or Unity and view with a VR HMD

[@Veptis]

Or bring the BLK, an iPad a laptop and a phone based HMD to show people some options with high quality scans within half an hour.

[@deepaksinghpujari719]

Hi, do you use direct point cloud/mesh data in Cinema 4D or Maya or convert the point cloud data in low poly mesh in Revit to reduce the size of the obj file to work with. because mesh data in obj format would be too heavy to work with.

[@The-Shihab]

hi I was asked to create a virtual walk through for a horse training farm. I am a metterport user and I know that MP won't cut it for this project because : 1- its a lot of outdoors scanning 2- the area is 80,000 SQM, not foot but meters. do you know if BLK360 can scan such size? thank you

[@rainman2543]

What are the average file sizes of those point cloud files?

[@CinematographyDatabase]

About 300 MB for the High Resolution ones with normal photos

[@rainman2543]

Cinematography Database - I was assuming it around GBs, but 300 MB sounds very manageable.... Thanks for the reply!

[@mr_DppD]

Hi, Matt. Those RedShift RenderView is a plugin? This is not the default Cinema feature?

[@CinematographyDatabase]

Redshift is a third party (separate purchase) GPU render engine that I use now, it's 100x faster than the native C4D Physical Render engine

[@mr_DppD]

WHOA! So fast answer! Thank you :)

[@acorgiwithacrown467]

How is it able to scan behind stuff?

[@LE007EL]

Whats the best online course I can learn about lightning? The Right Amount Of Light, Giving Light Shape, Basic Technique,Making And Controlling Light, How light works ?

[@timelschner8451]

Very nice video, thank you! What is the accuracy of the scan? error in mm ?

[@CinematographyDatabase]

I think it falls off the further the scan is, but it says less than 6mm for most of the points

[@leecaste]

An additional step is to make hdr photographies at different points like with the lidar and then reproject those hdr images as textures on the cleaned models so you have true lighting and reflections in case you want to use the original lighting of the location you scan, there's a bunch of videos showing this technique on youtube.

[@CinematographyDatabase]

Can you link me to those videos? I haven't been able to get stills photos added to this workflow yet

[@leecaste]

Cinematography Database it was done some time ago and you may not be familiar with the software but it's just basically projecting and texturing with hdr textures instead of regular ones. kzbin.info/www/bejne/gpLciJmNlreohpY

[@leecaste]

Just play from the beginning, I think I messed something up when copying the link 😜

[@leecaste]

Here is a three part link, don't worry about the ptex stuff, the interesting part is how you can illuminate the scene with hdr texturing, you can do pretty much the same with any software or even place a camera in cinema4d, take a screenshot, use that screenshot in photoshop to paint in with an hdr photography after matching as close as you can and go back to cinema4d and use the same camera to project the texture onto the clean geometry. kzbin.info/www/bejne/Z5WbqqOdqradfNk

[@leecaste]

Ross Gilbert I watched it long time ago and don't remember exactly but I liked the idea of projecting hdr (yes, high dynamic range images without tonemapping) onto the geometry because usually it's used just for environment lighting. I sometimes use hdr pictures from softboxes as lights but I think adjusting and reprojecting the pictures onto geometry has to be done manually unless you have a dedicated device as far as I know. You could also make hdr photogrammetry but this takes away the reasons that makes lidar so comfortable. Would be cool if this leica device took high quality hdr pictures instead of regular ones but I assume it's not designed for film or vfx.

[@junavo]

How I convert Point cloud to Mesh model?

[@CinematographyDatabase]

Reality Capture

[@junavo]

@@CinematographyDatabase Thank you I will try. I see price is very expensive.

[@junavo]

I just buy BLK360 but I can't export in mesh file.

[@CinematographyDatabase]

@@junavo all software around LIDAR is expensive. Are you using Reg360 or Cyclone? The Autodesk software I believe is deprecated now.

[@junavo]

@@CinematographyDatabase I use Autodesk Recap Pro, I'm waiting license for Cyclone 360 but I don't know it's can convert to mesh or not.

[@Ali-kr1dy]

Can you give scan so i can try in my 3d software

[@AzadBalabanian]

Hell yeah. These video renders are awesome! You’re doing that in Recap?

[@CinematographyDatabase]

The fly through animations were made in ReCap Pro, they are point clouds not meshed though

[@Veptis]

I don't think this is that much of a thing you would need to do. Maybe of a location or a build set for lighting... But a stage that is basically a giant room with really simple geometry? I strongly hope that studios have floor plans and some form of architecture plans with the light installation, nobody build this with only paper plans. The scan is rather useful for something that has highly Complex geometry, or is a natural environment and you need to take a proper scan of it for post purposes like relit shadows or reflections

[@CinematographyDatabase]

Very few stages have accurate floor plans aligned with the grid and support structures or obstacles like AC, pipes etc. I know from shooting at lots of stages over the years

[@Veptis]

Cinematography Database buy going in by yourself into the empty stage for 1 hour and make some scan is kind of expensive as well. And you have to get a spot in advance as this is for pre production. It would be great if studios could start to offer really good digital models of their stages with accurate grind structures for planning, and it only needs one to start and competition will pick up.

[@Luckylukeproduction]

Where can I buy the LIDAR?

[@anton826]

internet :D only on the price of 18.5k$ :D good luck

[@AlmightyUniden]

With the power of this device... I don't think it qould take really long to recover that investment. It is sick

[@AndrewPRoberts]

SergentBoucherie Not if I get there first

[@TehMr]

Sami Salami to be fair,cinecameras are way more expensive than that.

[@AlessandroBK1]

Semplicemente meraviglioso...

[@IndianaCRC]

oops, Matt, you forgot your "Plan better, shoot better" famous tagline!

[@blackstone953]

I wonder if it's legal to scan a place without authorization

[@CinematographyDatabase]

I think it's the same as taking photos. Permission is best. People also get kind of suspicious near it. It also scans through glass into houses, so it's a bit more invasive

[@EDDY69]

HAhah "suspicious" Well it does look like a murderous robot out of Portal. It's probably intentional that Matt brought up that it can scan through windows and that it's an issue. Ryctus you can photograph nearly anything, but bathrooms and into peoples houses seem to be where the legal issues start in the US.

[@Tv1Apple]

Standing still is gonna be illegal soon, for fcks sake !!!

[@darkgreenguitarist]

Federal and Government building yes you need permission.

[@Tv1Apple]

darkgreenguitarist I highly doubt that any law states specifically that you can’t scan in a government building, for one simple reason - this technology is rare and new as shit. They can’t see freakin future

[@LukeHildreth]

very cool

[@TerenceKearns]

This would be great in Unreal Engine 4

[@mike3dfx863]

the price is ridiculous!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
