“…Umbilics have long been reported in the literature [54][55][56] and have accompanied liquid crystals since their discovery in 1889 by Lehmann [61], who called these structures kernels. Later, they were observed in a similar experimental setup by Freidel, who also resolved their detailed topological structure and called them noyaux [62].…”

“…Lehmann studied the material and discovered that the liquid at the mesophase exhibited a double refraction effect, characteristic of a crystal. Because it shared characteristics of both liquid and crystal, he named it "fliessende krystalle" and the name "liquid crystal" was born [2].…”

The modern history of liquid crystals has been dominated by the development of electronic displays. These developments began in 1964, when Heilmeier of RCA Laboratories discovered the guest-host mode and the dynamic-scattering mode. He thought a wall-sized flat-panel color TV was just around the corner. From that point on, twisted-nematic (TN) mode, super TN mode, amorphous-Si field-effect transistor, and room-temperature liquid crystals were developed. In the beginning, liquid-crystal displays (LCDs) were limited to niche applications such as small-size displays for digital watches, pocket calculators, and small handheld devices. That all changed with the development of the notebook computer industry. In 1988, Washizuka et al. of Sharp Corporation demonstrated an active-matrix full-color full-motion 14-in display using a thin-film-transistor array. The electronics industries now recognized that Heilmeier's 25-year dream of a wall-hanging television had become reality. LCDs could be used to replace existing cathode ray tubes. Through the cooperation and competition of many electronics giants, the LCD industry was firmly established.

“…With the growing size and complexity of simulations, the visual aspects of the scientific investigation are becoming, in several fields, a priceless asset for the research. Our interest in Virtual Reality Scientific Visualization arose from research on complex materials like liquid crystals [1]- [4] and short fibre reinforced building materials [5]- [7]. The main difficulty with 2D visualization and typical "3D"-ish visualization on 2D computer screens is, that the depth impression is very difficult to achieve with thin and elongated objects like fibres.…”

The paper investigates the beneficial contribution of visual feedback in the development of an algorithm for the automatized analysis of fibre orientations in short fibre reinforced composites. Of special interest was steel fibre reinforced concrete (SFRC), a multi-disciplinary research area involving material sciences, physics and civil engineering. More in detail, this paper explains how scientific visualization techniques, employed on a Virtual Reality environment, contribute to the understanding of the SFRC properties, both for research and educational aims. Furthermore, the analysis algorithm to obtain fibre orientation distributions from noisy tomography scans is presented.
