Scanning an environment with Agisoft

This is a very simple environment scanning test using a single camera and Agi PhotoScan, I know its been done before 1000 times but the results are very encouraging.

Point cloud view in Agi, again this was a quick test and amounted to nothing more than a few shots with a DSLR. Next time we do this we are going to try a multi camera approach to try and capture an entire section of the environment with one shot.

 

We didn’t take any top down shots of the rock hence the horrible sky coloured bubble.

The texture maps are average baked at 7,000 x 7,000 for this example, they are not bad but poor lighting on the day means there is a lot of baked in shadow.

It really is a very easy thing to do, it should be interesting to see how far we can push it. Being able to capture a clean detailed textured environment has so many potential applications Imagine a photo realistic environment like this running in unity with an oculus rift, watch this space 🙂

Skin shading in Modo

Or resident Modo artist Ross Mansfield has been slowly converting us all to Modo. Having always used Lightwave 3D for rendering switching over wasn’t much of a problem. One thing that is immediately noticeable is the ease of which you can get incredible looking renders in little to no time. This is our first skin shader test, bearing in mind no one in the studio has ever used it for skin shading before this test took about 2 hours from start to finished. Simply incredible software!

We used one of our full body colour scans from the scan store as a test subject. with a few simple epidermal / subdermal / spec and bump maps we managed to achieve some great results

Dynamic Pose Capture

We had the pleasure of working with some incredibly talented sculptors, Fabien Merelle Christophe Chabenet and Pascal Molina

We scanned Fabien using a combination of Artec scanning for the body and photogrammetry for the face. Obviously this was a very hard pose to hold and capturing it was a difficult task but with a bit of patience and lots of Artec Studio know how we managed to produce a very clean scan.

The head was captured with the Artec but in order to get a perfect expression we used our 18 camera AGI rig to capture the expression, this was then combined with the Artec scan in Zbrush to create the final model.

The final piece will be printed and re sculpted into a 5m tall! version of the original sculpture below

Added some more scans to the store

We are slowly getting though our massive backlog of 3D scans. 5 more have just been uploaded to the store.
