The term 3D is frequently used to describe a spatial representation of a structure on a 2D plane, such as a monitor.

Stereoscopy (from the Greek stereos meaning “solid” or “three dimensional” and skopeo meaning “to see” or “to look”) is the production and reproduction of images with a three-dimensional impression.

Three-dimensional perception is normal for humans, all primates, and most predators and is necessary for their survival. Due to the distance between our two eyes, we see two slightly different images. The brain merges these two separate images to form a three-dimensional representation of viewed objects in relation to distance and space. Wherever the need for orientation arises, the importance of stereoscopic vision is central.

After the invention of photography in 1829, the physicist Sir Charles Wheatstone constructed the first stereoscopic viewing device three years later. The first stereoscopic recording followed in 1841. Due to rapid technological development, devices are now available that enable a spatial illustration of real world environments, as well as virtual realms of the imagination. Stereoscopic photo or video productions are no longer exotic projects. Today they are common phenomenon.

Because of its faster processing capability and more flexible neural network, the human brain is much better equipped to create three-dimensional perception than any available camera system. In order to build a better 3D camera system, it is therefore necessary to reassess the laws of space and distance and to apply this expanded understanding to the technical challenge. An acquisition of habits and trends of two-dimensional productions is not possible. The objective of a three-dimensional production is to provide the viewers with spatial guidance in a tangible space in order to achieve a more complete and conscious perception of the content.

Over 20 years ago, Karlheinz Gelhardt, founder and Chief Architect of Invistra, realized that a new and innovative approach to the challenge of 3D videography was needed. In collaboration with a number of talented partners, he pioneered the design and implementation of a set of integrated technologies designed to deliver a significant advancement in the art of 3D video recording, broadcasting, and streaming. The results are the products and platforms offered by Invistra today.
