Tennis Esports - Best Ball Physics in the VR Tennis Market

Our aspiration was to create the ultimate tennis experience that feels like youre actually on the tennis court. Physics is a crucial part of that. We wanted players to not even notice the difference between our virtual game and a real-life strike. So we aimed to deal with any situation that could occur in a real game combinations of any ball speed spin or racket motion. The challenge of recreating a real strike is immense. Usually the ball is travelling at fast speeds towards a rapidly moving racket. But due to hardware limitations there are huge gaps in the information we get. We sample the racket swing multiple times a second and due to racket speed two consecutive samples can be up to 25 cm apart. But with our custom continuous collision detection we are able to bridge that gap. We can accurately estimate what is happening between those samples and predict each hit with precision. Early on when evaluating our simulation we realized that there was a difference between peoples perceptions and objective measurements. To truly imitate reality we needed comprehensive data on ball and racket collisions. Unfortunately the data available in the tennis science community was incomplete and inaccurate for our needs so we had to create our own database of measured racket and ball motion. When creating the simulation we realized that the state-of-the-art physics engines and existing scientific research couldnt deliver the precision and accuracy we needed. So we teamed up with the technical university of Vienna to create an immersive user experience when striking a ball in VR. The main challenge with this project is creating a collision model that is capable of real time predictions of the ball velocity and ball spin after ground and racket impact. Therefore we have to identify relevant effects and associated parameters influencing the impact behavior. During an impact between a tennis ball and a racket several effects occur such as strong deformations of the ball vibrations of the racket and overspin effet to name just a few of them. All these particular processes make the impact a quite complex dynamic programme where existing theoretical approaches are not providing sufficiently accurate models. With our mathematical model we could easily simulate different ball types rackets and environments. We made it work seamlessly in real-time multiplayer matches on available mobile devices even if players were on opposite sides of the globe. Together were bringing the court to life like never before! Download the app: Website: Discord: ,
