specular reflection

[′spek·yə·lər ri′flek·shən]
(physics)
Reflection of electromagnetic, acoustic, or water waves in which the reflected waves travel in a definite direction, and the directions of the incident and reflected waves make equal angles with a line perpendicular to the reflecting surface, and lie in the same plane with it. Also known as direct reflection; mirror reflection; regular reflection.

The color of specular reflection is determined by the object's surface spectral reflectance, which is mostly constant throughout the visible spectrum.
2[degrees]), the case has a fatal problem because the specular reflection size is just 1 pixel.
The most of studied surfaces have a high gradient of the BRDF for the observation angles near the direction of specular reflection and of the BTDF for direct transmission.
The specular reflection properties in the scattering from rough surfaces have been demonstrated [6,9].
t] follows rule of specular reflection and complies with the surface function of a torus.
s] and the axe Z (the direction of specular reflection or refraction).
Notice, for instance, the types of figures typically associated with such rhetoric: the photon is usually drawn such that normal and immediate specular reflection back out of the cavity is discounted (see Figure 3A-B).
If sunlight striking the ground at B causes a specular reflection off the perfectly horizontal mirror-plane ABC (whose length is exaggerated for clarity and to which BD is the normal), then the reflected ray is deviated by an angle equal to i.
of Technology, Sydney) describes how to write a ray tracer step-by-step, starting with design and programming and some essential mathematics and theoretical foundations, moving to such details as antialiasing, sampling techniques, mapping samples to a disk or a hemisphere, perspective viewing and developing a practical viewing system, nonlinear projections, stereoscopy, lights and materials, specular reflection, shadows, ambient occlusion, area lights, ray-object interconnections, affine transformations, transforming objects, regular grids, triangle meshes, mirror reflections, global illumination, simple and realistic transparency, texture mapping, procedural textures and noise-based textures.
In the ground reflection range, a constructive interference between the direct ray from the source antenna and the specular reflection from the ground is utilized to illuminate the test zone.
By offering both ATR and specular reflection sampling geometries in modular form, the user can choose the best measurement method for a range of sample types, including liquids, powders, gels, creams, films and reflective surfaces.
