This is the first test using our 80 x Canon DSLR full body scanning system. We are able to capture any pose in full colour in approximately 1/10,000th of a second. With this being our first test there is definitely room for improvement in terms of texture quality and capture volume.
Our custom built scanning rig
Using 80 cameras gives us an immense amount of texture detail.
Using one of our latest generation head scans this tutorial takes you through the process of creating and rendering realistic looking Skin using Modo 601.
Duration :: 70 minutes
Video Format :: MP4 H.264
Tutor :: James Busby
Required Software :: Modo 601 or higher, Photoshop, Zbrush 4R5*
Data Set includes:: Head Scan ZTL & OBJ, All Texture maps in PSD format, Final Modo scene file
Download size :: 1.5GB
We look at the ZTool using Zbrush 4R5 and export the mesh and normal map into Modo where we apply both diffuse and colour and set-up the lighting.
This chapter looks specifically at the lower dermal skin texture and SSS settings.
Upper dermal and Diffuse tint textures are all covered in this section
Learning how to control the specular highlights using very easy to create maps in photoshop
A very quick and easy way of generating great looking bump maps from the diffuse colour map
Rendering the fully shaded head using Modo’s preview render as well as some great HDRI lighting set-ups using SIBL
We have upgraded our Agisoft photogrammetry rig with a further 12 cameras giving us a total of 30 x canon’s
These are our first tests capturing a full 360 degree head in 1/10,000th of a second the camera layout still needs some tweaking but these early tests are very encouraging. The new version of Agisoft has an incredible mosaic texture blending allowing for super crisp high res textures, this combined with properly unwrapped UV’s gives some amazing results.
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 🙂
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
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
We are slowly getting though our massive backlog of 3D scans. 5 more have just been uploaded to the store.
We received 3 6cm prints of our kick boxer scan from PD Models today. considering the size of the model the quality is excellent. They were good enough to provide us with 3 version of the same model one primed and polished, one with just the primer coat and the last one in the raw material.
We are working hard to reduce our full body scan time, initially we started with full body tests taking as long as 30 seconds using only 9 cameras, however over the last few weeks we have managed to bring that down to 5 seconds using a new 16 camera set-up with 2 more cameras for the face 18 in total.
Obviously the definitive solution is to buy 100 cameras, reducing the scan time to that of the shutter. However we are confident that a 20 – 30 camera rig is capable of capturing very high detail full body / head scans.
We are trying to keep our rig as minimal as possible at the moment we can pack it into a few cases which is great for portability.
We have just released the first of many full body 3d Scans. these are simply intended as clothing / wrinkle reference for digital sculpters, there are only 9 at the moment but over the coming weeks / months we are hoping to add a lot more including full body anatomy scans.
