The Yost Labs 3-Space Mocap Studio is an open source motion capture application that uses the Yost Labs 3-Space Sensor™ devices. The interface is similar to other motion capture applications (e.g. Blender), but is more convenient in getting started with the 3-Space Sensor devices since the application was created for them. It automatically searches for 3-Space Sensor devices already in use by the computer on start-up of the application and can load in previous sessions that saved off 3-Space Sensor information. However, it can only set-up and record motion data. It cannot edit or clean-up the motion data like other motion capture applications. Do not sweat though, because the Mocap Studio can export its motion data using the BVH (Biovision Hierarchy) format which is a widely used form for motion capture data.
The Mocap Studio interfaces with the 3-Space Sensor devices through a Node Graph interface window which allows the creation of complex node configurations to facilitate communicate with 3-Space Sensor devices. It is within this window that you can edit 3-Space Sensor settings and pair 3-Space Sensor Dongle devices with 3-Space Sensor Wireless devices . The Node Graph can also manipulate the orientation data coming from the 3-Space Sensor devices to allow to sensor re-targeting or other complex mocap rigs.
We offer a Mocap Bundle that includes 17 Wireless devices and 3 Dongle devices to get you started on motion capturing at an affordable price.
We also offer Strap Sets that can be used for placing the 3-Space Sensor devices.
