Скачать или смотреть MolVR & Automatic Label Display of Atoms

This is a real-time rendering on MolVR (www.molvr.org)

MolVR is a very early version of Molecular Visualization software using both AAA 3D engine and Virtual Reality display, such as Oculus Rift

Video features:
1) Scientifically accurate representation of the RXR protein, a molecule produced by our cell to capture a signal and regulate gene expression accordingly

2) Technical: alternate materials/textures for atoms, giving a sense of "detail" at close range

3) Technical 1: the angle between the camera forward vector and the label/text orientation vector is computed. The transform matrix of the label object is then updated accordingly to always face the viewer (billboard concept).

4) Technical 2: the distances between the camera (point of observation) and each atom entering a collision box surrounding the camera are computed. When an atom is sufficiently close to the camera, its label is shown; when moving away, its label is hidden

Aside from the performance optimisation achieved by displaying only a few labels rather than several thousands or tens of thousands, this Automated Labeling of Nearest Atoms increases the readability of texts by avoiding to superimpose too much labels
