![]() (Abbreviated to LIE or CLAV)ĭuring the Range of Motion recording, it will occur that markers disappear during an extreme pose, because the cameras only record light reflections. We will label the reflective markers on the suit, as captured in step 2, with matching body parts, like Left Inner Elbow or Clavicle. The actor becomes a simplified 3D skeleton on screen and the sticks are the “bones” of the skeleton. This is so that Blade recognizes the markers as body parts and knows what the movement limits of the actor are.īefore recording animations, sticks will connect the markers on the actor. See this as a small workout with spinning arms, bending back and forth and kicking the feet. We let the actor do a so-called “Range of Motions.” (ROM) He or she will exercise all extreme rotations of the body. The actor’s markers will appear on the screen as he or she walks around the studio. Bad calibration Good calibration Step 2: Calibrating the actor Also, make sure they capture no other light than the reflective markers on the actor’s suit. In the 3D viewport of Blade, all cameras should aim and stand the exact way they do in real life. It is important to calibrate the cameras. Let’s give an overview of what we do during a recording session. Eventually, I summarized the workflow into an easy-to-follow manual, which everyone here can use in the future. I scrolled a lot through the giant database of Vicon manuals. I took some time to figure out all the technical aspects of the Mocap workflow. We have been through a lot of experimenting and try-outs before we came to a satisfying point. What happens during a motion capture session? ![]() The software is sensitive, and it is easy to make mistakes, so to make it work you will have to follow Vicon’s setup of the cameras and marker placement on the suit. We place the markers on the body where a lot of movement happens, like the elbows or the knees. The camera will only record the movements of the markers and the software will recognize them as a human skeleton. That is why the actors who will record the animations, wear black Velcro suits with reflective markers spread across their bodies. The cameras do not record image views, but only light reflections. We are using the Vicon Vantage camera set with their matching software Blade. So, what is necessary for recording animations? Roughly sketched, we have 12 cameras hanging at the top edge of the installation and 4 cameras hanging at waist height to record the legs and feet. What do you need to record animations? The studio has 16 cameras, which are arranged in a specific spatial setup in the room. If you are interested, we would love to hear from you! The Motion Capture equipment We are often looking for students or organizations who would like to work with us to create and experiment with Motion Capture. ![]() ![]() It is currently set up in our former test room. Together with NHL Stenden, the owner of all the equipment, we decided to breathe new life into the studio by setting it up in our office and helping with the operation of the equipment. The Motion Capture studio was previously located in another room in the Blokhuispoort (the building where our office is also located) in Leeuwarden. We would like to give you an overview of what you can achieve with Motion Capture animation and our personal experiences during the setup of the studio. From now on, we can put on the skin-tight, white dotted motion capture suits ourselves and record real-time animations to implement in our games. That’s why we are very excited to announce that our own motion capture studio here in Leeuwarden, is finally up and running. High-quality motion capture animations are best captured in a professional studio. Although these are interesting techniques, these animations are usually not of the best quality. As seen on Instagram and Snapchat filters. You can even do facial tracking with your own smartphone. ![]() Over the past years, it has become much easier to record these animations yourself with the arrival of the Kinect for example. Although this technique has been used for over 20 years in the film, animation and later the game industry, it has now made a boost in its regular usage. Motion Capture is Recording real-life movements from actors and converting them into hyper-realistic 3D animations. ![]()
