point light source उदाहरण वाक्य

उदाहरण वाक्य

1. :: : Using my def of a point light source as one where all the light hits a single rod or cone in the eye, the nearest planets don't qualify . talk ) 17 : 09, 6 August 2008 ( UTC)
2. The principle of operation is purely one of geometric optics : A point light source produces a glint on a curved specular ( shiny ) surface; this glint appears to travel on the surface as the eye or light source moves.
3. Advanced features like database paging, texture paging and point light source management ( for flight simulation ) and intersection testing for collision detection would also have dedicated processors allowing asynchronous I / O and processing to occur without negatively impacting graphics performance.
4. The researchers, writing in the journal Nature, estimate that the ophthalmosaurs could probably have detected point light sources ( like those from photoluminescent prey ) in deep water, and suggest that the creatures dived to depths of close to 2, 000 feet.
5. A biased rendering method is not necessarily wrong, and it can still converge to the correct answer if the estimator is caustics generated from a point light source, as it is highly unlikely to randomly generate the path that directly reflects into the point.
6. It is frequently used in real-time computer graphics and ray tracing, where the mirror-like specular reflection of light from other surfaces is often ignored ( due to the more intensive computations required to calculate it ), and the specular reflection of light directly from point light sources is modelled as specular highlights.
7. For the purpose of measuring illumination, the candela is not a practical unit, as it only applies to idealized point light sources, each approximated by a source small compared to the distance from which its luminous radiation is measured, also assuming that it is done so in the absence of other light sources.
8. It continued in use in more specialized applications where a high intensity point light source was needed, such as searchlights and movie projectors until after World War II . The carbon arc lamp is now obsolete for all of these purposes and is only still made for very specialized purposes where a high intensity UV source is needed.
