In its simplest form, volumetric capture records a performance from multiple angles over time using synchronized cameras, lights, and sensors to create a 3D data point cloud that can be used in animation and other digital media applications.
A great example of this technology is in Hollywood blockbusters such as Avatar, where actors are able to act out scenes completely within a computer-generated world while still capturing realistic movement. This type of innovation takes virtual production far beyond what was previously possible.
When performing volumetric capture, best practices include setting up a consistent lighting array with stable frames per second and capture rate, as well as using high-quality equipment for optimal results. Additionally, if you want to obtain proper body motions or facial expressions, you may need to integrate additional tracking tools.
Experts who specialize in volumetric capture often come from backgrounds in motion-capture engineering, computer graphics, photography, and video production. They have an extensive understanding of how the hardware works and experience working with software like Unreal Engine and MotionBuilder. Their knowledge allows them to produce stunning visual effects in an efficient manner.
Overall, volumetric capture plays an essential role in virtual production today by enabling us to create believable worlds populated with amazing characters and environments.
