Dumitru Daponte and the 3D cinema

Dumitru Daponte (1894-1956) was a Romanian engineer, who invented in 1924 the 3D cinema.

After World War I began the boom of film industry. It was the silent film era, black and white, interrupted every 10 minutes to change the film coil. The dialogues were designed separately, on a black background and some film scenes were interrupted to provide the necessary explanation for the action understanding. However, the theaters were full and it was obvious that the new industry had a golden future.

One of the problems that Dumitru Daponte tried to solve is related to playback images in relief (the classic projection has only width and height, not depth, making the screen to be viewed as a sequence of shots). Techniques used in this way were different: the use of glasses with colored lenses, the projection of images on a curved screen etc.

Before Daponte, another Romanian had made a similar attempt: N. Iliescu Brînceni developed a kind of binoculars, which each spectator had to hold to eyes to see on a screen two distinct sets of images superposed to obtain the sensation of relief.

Dumitru Daponte began to work on his invention in 1916, doing research and experimentation in Italy and England, countries where the film enjoyed a great interest. He then made a device for obtaining a stereoscopic effect, based on the idea that the relief conditions must be created since the time of registration of the film. Daponte built a camera with two objectives (the ones by then had one), at approximately 6 cm distance from each other, trying to get the relief effect by projecting simultaneously each pair of captured images. The engineer based his invention by the fact that man sees with two eyes and the perception of relief is due to this double simultaneous reception of the image. His apparatus also contained a device allowing the adjustment of the distance between the two objectives. The two films thus obtained were then entered into a special recording device, such as the two images to be implemented on a single film. His invention was patented in France (Patent no. 592963) and England (Patent no. 222173).

Daponte's invention, introduced in 1924, enjoyed great interest and represented a step forward in addressing this crucial issue for the future of film industry.

Eugen Pavel

Dr. Eugen Pavel is a Romanian scientist and the inventor of the Hyper CD-ROM, a 3D optical data storage medium with a claimed initial capacity of 10 TB and with a theoretical capacity of 1 PB on a single disc. It is considered by some to be the next revolution in computer storage.


Dr. Pavel graduated with a physics degree from the University of Bucharest in 1976. He obtained his doctorate in Physics from the Romanian Institute of Atomic Physics in 1992. Eugen Pavel has published more than 40 books and articles, and he is the holder of 62 patents and patent applications.

The Hyper CD-ROM is a tridimensional multilayer optical memory, based on the phenomenon of controlled extinction of the fluorescence. The Hyper CD-ROM allows the recording of information inside the “shelves” of a glass disk using laser beams. Such a glass disk has a storing capacity of over 10,000 Gigabytes (GB) of memory - an amazing size in comparison with those developed by the highest level computer firms and benchmarks - that allows storing of approximately 10 million books of standard format. It is in fact, an “optic tridimensional multilevel memory” so it can store data in over 10,000 different levels inside a glass disk 10 mm high and 120 mm in diameter. The most attractive aspect is that the support for storage (i.e. fluorescent photosensitive glass) is a very stable in time medium (information can be read during all the life of the glass - estimated to at least 5,000 years). Great IT companies as IBM, HP Compaq or Philips are very interested in this revolutionary technology.


Eugen Pavel won: The 'WIPO Award for the Best Inventor', granted by World Intellectual Property Organization; 'Prize of the World Periodical Press Organization' and 'Gold Medal' at Brussels Eureka: 48th World Exhibition of Innovation, Research and New Technology; 'Gold Medal' at 32nd International Exhibition of Inventions, New Techniques and Products of Geneva; 'Prize of the Romanian Academy of Sciences for Physics'; 'Grand Prize of the Kent Premium Lights Annual Awards for Innovation' granted by British American Tobacco; Prize 'Prof. Ing. Dimitrie Leonida' granted by Romanian Technical Museum.
