Motion capture animation, commonly known as mocap animation, is a technique used in the entertainment industry to capture and record the movements of real-life actors or objects and translate them into digital animations. It involves tracking the position and orientation of specific points on a performer’s body or an object using sensors or markers. These movements are then recorded and applied to virtual characters or objects in a computer-generated environment.
Sony Mocopi is a full body tracking solution that makes use of an array of 3 DoF sensors to approximate positional tracking of the wearer’s body. This works in a manner similar to Shiftall HaritoraX, using a machine learning model and data from each 3 DoF sensor to produce an accurate estimation of the wearer’s relative body position.
While some motion capture software can be quite expensive, there are also free options available. Here are a few popular free motion capture software tools:
- Blender: Blender is a free and open-source 3D creation suite that includes tools for motion capture animation. It supports importing motion capture data and provides functionalities to edit, retarget, and apply the captured motions to characters or objects.
- NI Mate: NI Mate is a free motion capture software that allows you to use your depth sensors, such as Microsoft Kinect or Intel RealSense cameras, for capturing motion. It provides real-time tracking and supports popular 3D animation software, including Blender, Unity, and Maya.
- iPi Recorder: iPi Recorder is a free software that enables you to capture motion using multiple cameras. It supports a range of inexpensive webcams and provides basic functionality for recording and previewing motion capture data.
- Reallusion iClone Mocap Plug-in: Reallusion offers a free mocap plug-in for its iClone software. It allows you to capture motion using a Microsoft Kinect sensor and apply it to 3D characters in iClone for real-time animation.
These free motion capture software options provide a starting point for exploring motion capture animation without incurring additional costs. However, keep in mind that free software may have limitations compared to commercial solutions, such as fewer features or less advanced tracking capabilities.
