看了下介绍，有些地方还是非常智能的，比如笔刷工具，自动捕捉图像，以及GPU加速跟踪，都是后期流程中非常提高效率的地方。

Polish firm Flowbox has posted some really interesting new demo videos of Flowbox, its self-titled GPU-accelerated rotoscoping and compositing system.

The videos show some well-thought-out workflow features, including smart strokes, auto-snapping of roto shapes, ripple editing of points, and support for open splines.

The technology is currently in beta, and is due for a commercial launch in October.

Designed for VFX artists, by VFX artistsFlowbox has been in development for a while – the original closed alpha was announced in 2013 – but the team has only just started to make details of the feature set public.

Many of the developers come from VFX backgrounds: both co-founder Wojciech Daniło and CEO Mikołaj Valencia worked at Alvernia Studios, where Valencia was a VFX supervisor and head of motion capture.

Intuitive, time-saving workflows for creating and editing roto shapesThe heart of Flowbox is its roto toolset, which offers a nicely designed workflow for creating and manipulating roto shapes, as shown in the video above.

As well as defining shapes by placing points, the RotoSTROKE system enables artists to draw freehand strokes around objects, with Flowbox automatically detecting edges and distributing points along the stroke.

Once created, roto curves can be manipulated by moving points or Bezier controls, or by deforming entire shapes directly, and there are standard options for feathering the edges of mattes.

More interestingly, there are also options to auto-snap points defined in a previous frame to a new stroke; and a ripple edit feature, which interpolates a new point added to a shape into previous frames.

Both features look like great workflow time-savers. The system also supports open splines with variable widths, making it easier to rotoscope objects like tails or long hair.

Planar tracking, roto-painting and roto-rigging in developmentThe product website also lists some interesting upcoming features in Flowbox’s roto toolset.

These include a point-based and planar tracking system with the option to import tracking data from other software; a non-destructive vector-based roto-paint toolset; and a roto-rigging system.

The latter will enable users to “connect [roto] shapes using bones and joints” with Flowbox using an inverse kinematic solver to make the resulting rig follow the motion of a character on screen.

Plus compositing and animation tools; keying and collaboration to comeAlthough they aren’t shown in detail, Flowbox also includes a node-based compositing system – the interface looks more reminiscent of Flame than Nuke or Fusion – and an animation dope sheet.

The system is also capable of exporting data to Nuke.

Other planned features include keying, collaboration options, and a VR toolset.
