iPi Soft Announces Faster Tracking And Enhanced Animation Export Features For iPi Motion Capture Software

Version 3.5 of Markerless Mocap Solution More Than Doubles Tracking Speed; Includes Faster, More Accurate Calibration


MOSCOW, RUSSIA – iPi Soft, LLC, developers of advanced markerless motion capture technology, today announced significant upgrades to its iPi Motion Capture software application, including 2.5 times faster tracking speed when used with a Kinect sensor set-up, enhanced animation export functionality, as well as availability for single-actor projects and single-GPU configurations.

According to Michael Nikonov, founder and chief technology architect for iPi Soft, the new iPi Motion Capture tracking algorithm works faster than when the raw data is recorded via a Kinect sensor, with tracking speeds now available up to 60-70 fps (when using high-end video cards), versus previous Kinect recording rates of 30 fps. “The new enhancements to the software will allow us to implement a real-time feedback feature so users can see the tracking result transferred to 3D characters at the time of recording motions for optimized workflow,” Nikonov said.

Nikonov also noted that the new 3.5 version offers faster calibration for the Sony PS3 Eye camera set up, which now takes less than three minutes (dependent on the number of cameras used) when using a high-end video card. In addition, increased calibration precision has resulted in more accurate noise and defect filtering.

Customers working with Sony PS Move motion controllers to precisely track hands and head rotations, a process that used to take up to 10 minutes depending on length of recordings, now will enjoy nearly instant application of motion controllers data. iPi Soft development also continues to bring faster algorithms for use with Sony PS3 Eye and other RGB camera set-ups, scheduled for release later this year.

In addition to 2.5 to 3 times faster tracking speed (for Kinect sensors) – which is essentially real-time rendering, a long time benchmark for adoption with high-end users working in entertainment – the new 3.5 version features additional animation settings for working in third party applications for a smoother integration.

Other key features in iPi Motion Capture 3.5 include:

•    Availability for single-actor projects and single-GPU configurations.

  • New export tab controls allow users to rotate imported characters into proper orientation, useful for many popular characters, including standard Unreal Engine characters.
  • Motion can now accurately be transferred to imported characters with separate root bone and hips/pelvis bone. Users can map hip motions either to root or to hips/pelvis, which benefits game engine characters, including standard Unity 3D Engine and Unreal Engine characters.
  • Support for FBX format 7.5.
  • Added finger bones to motion transfer profile for Valve characters in SMD and DMX formats.
  • Users can select flashlight color for marker detection during calibration, useful in case of light backgrounds.
  • Timesaving hints added to GPU’s progress bar area during tracking.
  • Dialog with common actions available for the exported file shown after animation export and video export operations.
  • Numerous bug and “under-the-hood” fixes.

A complete list of the new feature enhancements in iPi Motion Capture 3.5 is available here.

Real-Time Feedback Development:

In addition to more than doubling the tracking speed with this latest version, the company remains focused on achieving real time rendering before the end of 2017.

“Our development efforts are focused on processing speed optimization and we expect to release a new version of iPi Motion Capture that will essentially offer real-time capability this year to deliver customers an overall improved markerless mocap workflow,” notes Nikonov.

Pricing and Availability:                                                              

iPi Motion Capture Version 3.5 is available on a subscription-based pricing model. Prices range from $45.00 to $2,495.00 depending on the version of software (Express, Basic, Pro) and duration of subscription. The Basic edition provides support for up to 6 Sony PS3 Eye cameras or 2 Kinect sensors, and tracking of single actor.

More Point Cloud Export Formats Added

Posted on: March 19th, 2015

Since the release of iPi Biomech Add-on a year ago, many customers requested us to extend the list of formats available for point cloud export. MATLAB and PCD formats were convenient enough for researches, but  not for animators.

In animation, point cloud can be used as a video reference, which makes life easier in many cases. iPi Motion Capture is the only commercially available product so far, that allows to obtain point clouds recorded with multiple Kinect sensors. Now you can use this product feature to its full extent.

New! The latest release of iPi Biomech Add-on (included in iPi Mocap Studio) supports export to  Krakatoa PRT, PLY, OBJ, Leika PTS formats that can be recognized by various 3d packages, including 3ds Max and Maya. Read More>>
