A glimpse in to Craig Cranes next movie

I just got given an image you may like to see which should be part of Part two of the Geomagic meshing tutorials by Craig Crane.

Enjoy.

Looks amazing. How is that possible? :)

Impressive. How many scans to get decent coverage for that?! :o

Jason. Sorry

Matt. I'm sure Craig will clarify but I would do 50-60 scans at a guess to do that sort of coverage.

Phil. 15 mil poly is about average

Masimo. In simple terms lots of setups for a full coverage and not survey coverage. Ultra tight registration. The right software and most import a complete and full knowledge of what the client needs and wants and lastly use every trick in the book to shave of any bottle neck in the pipeline. Speed and accuracy.

Look forward to seeing the workflow for that model. I am guessing that it is not just a meshed point cloud but that there is a lot more work in it.

Looks fantastic though!
If you want to make something simple, then take one thing away that still allows you to do the job. Don't add two more things, and say they both make it easier.

Nope. It is a meshed pointcloud.

My plan is to take you through the process of why the scan was required, and to how it was used in the film. Its more of an insight into why we make extensive use of lidar in VFX. The VFX pipeline is very specific, and requires a deep understanding of our requirements and how we work. Many lidar vendors in the past have fallen short on this knowledge, which is why more and more vfx houses now opt to do their own lidar. It keeps costs down, expedites delivery and ensures that the data is exactly what we require for the process. So, hopefully the video will be a little window into this unique way of working with Lidar

I have a magic button on my qwerty keyboard that is labelled "make mesh". ;)

The technical term for my approach is STSOoE

Roughly translated, thats "Scan the sh*t out of everything"

I find this approach works well.

When I don't have time to STSOoE, then I just have to scan the stuff that counts.

On this particular gig, I was faced with limited time, but lots of tools to get it done. I decided that if I worked fast and planned my route through the rubble STSOoE could be employed.

I had a couple of hairy moments, because unlike most set builds where the rock is painted polystyrene, this rubble was all real, with iron bars posing plenty of danger. I also have to ensure that the set is not disturbed. Moving props, or any set dec (set decorations) is a cardinal sin, and one that if broken could see your prospects of future work greatly reduced. So, whilst navigating the set, you also have to ensure nothing shifts.

So, I weaved through the set with the scanner, starting from the outside, and then tied the scanner down to a scissor lift and sent her up as 60 feet and got coverage from above. I did 53 scans in all. 8 of which were from the lift, with me controlling the 6100 from the ground via the ipad

I always scan with the post work foremost in my mind. What can I do to make my job easier as I do all my own processing right the way through to delivery? Do I use targets? Do I take notes of each scan position as I work my way through? When is the best time to do the scan? Do I toggle rez and laser power? Do I get a day off? Hopefully all these questions will be answered in ..

Not too shabby II

I'm currently lidar supervisor on several films at the moment, meaning that I also have to ensure that I don't walk straight into a bottle neck of data, as all the shows want all their data as soon as the scan is done (almost), so how I manage my time and projects is a critical part of the process.
