Digital animation techniques have brought many tools for making films. From ‘Luxo Jr.’ (Pixar1968) to the remake of ‘The Lion King’. The possibilities are endless.
You can give objects and figures any shape, lighting and atmosphere that you want, and regardless of physical cameras, you can take any point of view that you want. You can choose to move freely through each scene as if the viewer is part of it yourself. It takes some computing power, but modern computers can render this without problems.
But what if you want to create a scene of reality with real actors?
Is there a technique where, just like computer animations, you can choose every point of view you want and take every possible walk through the scene?
Yes, there certainly is and it’s called “Volumetric Video”.
