The results show that the measuring accuracy of BRDF depends on the precision of measuring platform, the sensitivity of measuring instrument and the stability of illuminating light source, and the modeling accuracy of BRDF is closely related to the measured data and optimization modeling method.
It is compatible with a variety of sources (including displays, single LEDs), as well as reflective surfaces illuminated with light sources.
When the channel is alternatively illuminated by light sources installed at both ends, the plankton escape from the light because of their anti-phototaxis and collide against the fin, resulting in actuation of the float.
The whole system is illuminated by a white-light source with an emission spectrum similar to that of a black body.
The sample is illuminated with a white-light source from the opposite direction and imaged with a CCD camera.
The PBR was illuminated by combinative light sources, including an internal illumination with optical fiber excited by solar energy (OF sunlight)) as well as external irradiation of tungsten filament lamp (TL).
Kei Acedera's images, which appear throughout as full-page, half-page and spot-art ink-wash drawings, seem to be illuminated by dramatic light sources, from a roaring fire to a flickering candle, visually expressing the gloom settled on a land that has not seen the sun in 1,728 days.
Among his several extended series were Blankets, for which he used cylindrical forms covered with patterns derived from Native American blankets; Seaforms, shapes evoking sea urchins, shells, and other marine life; and Chandeliers, large-scale hanging sculptures illuminated by natural light sources.
So its gazillions of pixels needs to be illuminated by external light sources rather than each pixel making its own light.
This image shows the original paintings (across the top), as illuminated by different light sources (from left, 6410K, 4291K & 3410K) and below are the same paintings reproduced by the AI in RePaint.
