  2. Ray tracing (graphics) - Wikipedia

    en.wikipedia.org/wiki/Ray_tracing_(graphics)

    In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images. On a spectrum of computational cost and visual fidelity, ray tracing-based rendering techniques, such as ray casting, recursive ray tracing, distribution ray tracing, photon mapping ...

    en.wikipedia.org/wiki/V-Ray

    V-Ray. V-Ray is a biased computer-generated imagery rendering software application developed by Bulgarian software company Chaos. V-Ray is a commercial plug-in for third-party 3D computer graphics software applications and is used for visualizations and computer graphics in industries such as media, entertainment, film and video game production ...

  4. Moiré pattern - Wikipedia

    en.wikipedia.org/wiki/Moiré_pattern

    Moire, or "watered textile", is made by pressing two layers of the textile when wet. The similar but imperfect spacing of the threads creates a characteristic pattern which remains after the fabric dries. In French, the noun moire is in use from the 17th century, for "watered silk". It was a loan of the English mohair (attested 1610).

  5. Acrylic fiber - Wikipedia

    The polymer is formed by free-radical polymerization in aqueous suspension. The fiber is produced by dissolving the polymer in a solvent such as N,N-dimethylformamide (DMF) or aqueous sodium thiocyanate, metering it through a multi-hole spinneret and coagulating the resultant filaments in an aqueous solution of the same solvent (wet spinning) or evaporating the solvent in a stream of heated ...

    en.wikipedia.org/wiki/Dyneema_Composite_Fabric

    Dyneema Composite Fabric. Dyneema Composite Fabric (DCF), also known as Cuben Fiber (CTF3), is a high-performance non-woven composite material used in high-strength, low-weight applications. It is constructed from a thin sheet of ultra-high-molecular-weight polyethylene (UHMWPE, "Dyneema") laminated between two sheets of polyester. [1][2]

    Diagram showing vectors used to define the BRDF. All vectors are unit length. points toward the light source. points toward the viewer (camera). is the surface normal.. The bidirectional reflectance distribution function (BRDF), symbol (,), is a function of four real variables that defines how light from a source is reflected off an opaque surface. It is employed in the optics of real-world ...

    Ultrasuede. Ultrasuede is the trade name for a synthetic ultra-microfiber fabric invented in 1970 by Dr. Miyoshi Okamoto, a scientist working for Toray Industries. In Japan, it is sold under the brand name Ecsaine. [1] It is often described as an artificial substitute for suede leather. [2] The fabric is multifunctional: it is used in fashion ...

  9. Path tracing - Wikipedia

    en.wikipedia.org/wiki/Path_tracing

    Path tracing. Path tracing is a computer graphics Monte Carlo method of rendering images of three-dimensional scenes such that the global illumination is faithful to reality. Fundamentally, the algorithm is integrating over all the illuminance arriving to a single point on the surface of an object. This illuminance is then reduced by a surface ...
