But Holo!
Holographic solutions in real-time and color for electronic displays.
As a reminder: A hologram is a two-dimensional surface that can diffract or distribute light in such a way that, when suitably illuminated by means of targeted interference, three-dimensional objects are created, technically speaking, reconstructed, which appear to be behind or in front of a surface.
However, holography is currently neither fully learnt nor are all the tools available or fully developed. Nevertheless, holograms or holographic technologies are no longer a vision of the future, but are increasingly being used for a wide range of applications: as a highly versatile technology for manufacturers of complex visualization systems. This also applies to already existing volumetric data, which can now also be displayed volumetrically, i.e. really three-dimensionally - and not only stereoscopically - by means of holographic methods.
Process, not product
It is not about a finished holographic display or product that can be ordered from a catalogue. It is about the very complex technology, the know-how or the possibility to realize such or comparable technical displays and products for and with customers according to their needs. Ideally, they can be used across the board for all applications and manufacturers according to the modular principle. This means that manufacturers or system integrators are able to produce their own devices and systems themselves, depending on the complexity, interfaces or technical requirements.
The existing data volumes are already too large to be checked with enormous effort. Not to mention validating the data. Holography, used for volumetric representation, creates a new approach here. Even huge amounts of data can be visualized in volumetric form and, depending on the form of representation, plausibility checks and even validation can be carried out very quickly. It is therefore no surprise that the first application scenarios in medicine and geodesy are planned. Furthermore, the holographic solutions are suitable for many areas such as scientific data representation or analysis, simulations, technical designs in architecture and construction as well as sovereign services and avionics.
Technology that inspires
Massive computing power is required for true three-dimensional representation. A Gundersheim sample display calculates around 1.5 billion light beams per second with a basic physical size of 36 x 25 x 10 centimetres and thus displays real three-dimensional medical computer tomography data for illustration purposes, for example.
Since existing data is also to be displayed volumetrically and a separate ecosystem of software, drivers and services already exists, this technology is compatible with a wide range of data formats. These include, for example, in addition to the well-known graphic formats such as OBJ, gltf or fbx, the graphic designs 3DS Max, Maya and Blender etc.
Translated into everyday life: An average mobile phone photo is between one and ten megabytes in size. A frame, i.e. a still image or a holographic scene representation, is about 150 gigabytes in size, depending on the display, resolution and size. That is fifteen thousand times larger. In order to be truly holographically powerful, computers must process about 25-30 of these holographic scenes per second. Since the higher the resolution of the representation, the greater the amount of data, the faster it grows to a huge scale. The challenge for developers is to reduce these data volumes to the essentials in a permanent optimization process in order to be able to address as large a volume area as possible in detail with available and affordable hardware and software.
