Trying to steal Vray's thunder.
I'm gonna wait for Steam version
Check out a very fast and easy-to-use tool for building 3D models of faces or heads based on photos called FaceBuilder. This plugin for Foundry Nuke is a part of KeenTools suite.
Here is the official description of some of the other features of KeenTools:
Accurate object tracking right in Nuke
Currently it works with rigid objects only, but later it’ll support deformable meshes tracking as well.
GeoTracker is developed using low level Nuke’s C++ API. That’s why it pretty seamlessly integrates into your familiar workflow. GeoTracker supports all OS and all versions of Foundry Nuke since 8.0.
Scene-based camera tracking
Camera Focal Length Estimation
Camera focal length heavily affects tracking and that’s why it should be known. But sometimes you have to deal with footage which is shot with unknown lens. Don’t worry — GeoTracker helps you to figure it out.
Fast model positioning via dragging points
