Ten24 and Axis Animation are seasoned partners, having worked together on several large projects over the years. We both share the same appreciation for visual quality.

Their new proposition was massive – to take our head scanning technology and produce assets for Halo Spartan Ops, one of the most loved game franchises of all time and also one of the most anticipated Halo releases in recent years. The benchmark would be high. Thankfully we had recently upgraded our photogrammetry scanner and were eager to set about the task.

Actors were cast and we headed off to meet them at Spotlight Studios in London. Our rig is designed to be fully portable with no wires, cables or cumbersome computer equipment inhibiting potential scanning locations and just over an hour after arriving for the shoot we’d assembled the equipment and were ready to go.

Traditionally scanning a head has been a fairly slow process with older structured light and laser systems taking up to 30 seconds to perform the scan. Whilst this might not seem like a long time any movement during the scan can drastically reduce the quality of the final mesh. Even breathing can result in severely misaligned sections of the model.   However we’ve overcome these issues by constructing a custom scanner that is able to capture a full head, in colour, in approximately 1/10,000th of a second by synchronising 18 DSLR cameras and four flashes. These capture a split second collection of multi angled shots that can be processed using stereo photogrammetry techniques to generate a high quality, distortion free scan/mesh.

 

 

The images are then processed using AGI photoscan and converted into a raw textured model consisting over over 4 million triangles.

 

The next stage is to load the scan/mesh into ZBrush for projection and clean up.  We use the QRemesher tool to create a much cleaner mesh over the top of the raw scan. This gives us a nice quaded  mesh to work with and we can also dictate the polygon resolution at the same time. The high resolution details are then projected onto this new mesh and cleaned up using traditional sculpting methods in ZBrush, all the while retaining as much of the original scans qualities as possible. [Often there’s an area of noise, hair or a wig cap to remove].


This model now serves as the base for another fully retopologised/UV’d mesh. This is either made by ourselves, or as in this case, provided to us by Axis Animation.

Due to the nature of the photogrammetry scanner, we are able to capture extremely high resolution, evenly lit texture maps as well.  As a result we supplied 8k colour maps for all the head models, and then bump, reflection, roughness and displacement maps to complete the asset package.

We reproject the scan details and textures on to this final mesh. Then finish off by creating eyes, eyelashes and teeth

 

We delivered the fully retopologised animation ready models with a complete set of textures including Colour, Bump, Spec, Reflection, Displacement and Normal maps

Using our state of the art optical 3D Scanning rig we are able to capture full colour 360 degree head scans with a 3D point accuracy of up to 0.1 mm. We offer a full retopology service using either our own base geometry or geometry supplied by you.

Our system can capture ear to ear expressions in 1/10,000th of a second in full colour. Perfect for creating ultra realistic blend shapes for your characters.

Raw scan data as exported from our optical 3d Scanner. Sub millimetre scanning precision means we can capture every detail.

High Resolution 3D head scan

Completed, retopologised high res models can be supplied in whatever format you choose, with the full range of texture maps including normal / Diffuse / reflection / specular / Sub dermal / epidermal / Bump and gloss, customised to your software, pipeline and lighting / render setup
