Abstract

The paper refers to construction methods and ways to 2-dimensional representations of d-dimensional Euclidean polytopes. As examples, the d-cubes and regular d-simplices are taken into a more precise consideration. Moreover, formulae for metrical quantities of some special polytopes are derived.

... The SI unit of luminous intensity is the candela (cd) [15]. The candela is one of the seven SI base units, it is formally defined as following: BThe candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 5.40×10 14 Hz and that has a radiant intensity in that direction of 1⁄683 W per steradian (square radian)^ [9,10]. ...
... By solving Eqs. (9) and (8) we can derive: (10) gives a succinct formula to calculate the luminous intensity of a given direction. By combining Eq. (10) and Eq. ...

In this paper, we present a novel display assembly which is specially designed for the immersive system to enhance the sense of immerse. In particular, we aim at improving the display when a bright object, such as a light source, appears in the field of view. In the proposed assembly, we adopt a spot light to generate a high intensity beam. When the beam hits the screen, a hot spot is formed to imitate the light source displayed on screen. A galvanometer is employed to deflect the beam so we can track the moving of the light source displayed. Based on the basic laws in photometry, we deduct a series of formulas which could calculate the intensity of the beam and to estimate the gain in the contrast and dynamic range.
