The Pixel Farm has released what it says is a completely redesigned version of its 3D camera tracking and matchmoving application, PFTrack 2011.
PFTrack 2011 feature extensive plate preparation tools and lens distortion management, with enhanced tracking tools for both single stereoscopic camera setups, and geometry-based camera and object tracking, image-based modelling and scene reconstruction.
Now featuring a node-based flowgraph architecture, PFTrack 2011 also gains fully integrated Python scripting and workflow customisation tools, so facilities can access the underlying metadata management core of PFTrack 2011 within other tools.
PFTrack 2011 has been completely rewritten as a 64-bit, GPU-accelerated application. The geometry tracking functionality has been enhanced to support tracking of deformable objects, such as an actor's face while speaking, in addition to solving camera and rigid object motions. Since the track is accomplished using the tracking geometry's vertices as opposed to point or pattern trackers, The Pixel Farm says that geometry tracking in PFTrack 2011 conquers many of the typical pitfalls that plague conventional tracking operations such as glints and highlights.
Image modelling and texture extraction nodes generate detailed geometry for scene fitting, shadow boxing and set reconstruction. A set of modelling primitives can be positioned in 3D space and edited to match the image data, or new models can be constructed. Per-pixel Z-Depth extraction now supports masks, used to specify the relative depth ordering of objects in the scene, producing a greyscale depth map image and triangular mesh geometry.
Reengineered optical flow tools calculate dense optical flow fields describing the apparent motion of objects relative to the camera plane, and features retiming of clip and motion data to increase or decrease the apparent frame-rate of the camera. Retiming after a camera solve will also retime the camera solution, meaning shots do not require a re-tracking do to editorial decisions later in post production.
PFTrack 2011 is available now and costs US$3,300 (around £2,030).
