  2. Volumetric lighting - Wikipedia

    en.wikipedia.org/wiki/Volumetric_lighting

    In volumetric lighting, the light cone emitted by a light source is modeled as a transparent object and considered as a container of a "volume". As a result, light has the capability to give the effect of passing through an actual three-dimensional aerosol (e.g. fog, dust, smoke, or steam) that is inside its volume, just like in the real world.

  3. Three-point lighting - Wikipedia

    en.wikipedia.org/wiki/Three-point_lighting

    Three-point lighting is a standard method used in visual media such as theatre, video, film, still photography, computer-generated imagery and 3D computer graphics. [1] By using three separate positions, the photographer can illuminate the shot's subject (such as a person) however desired, while also controlling (or eliminating) the shading and ...

    en.wikipedia.org/wiki/Microsoft_Power_BI

    The first release of Power BI was based on the Microsoft Excel-based add-ins: Power Query, Power Pivot and Power View. With time, Microsoft also added many additional features like question and answers, enterprise-level data connectivity, and security options via Power BI Gateways. [10] Power BI was first released to the general public on 24 ...

  5. Hard and soft light - Wikipedia

    en.wikipedia.org/wiki/Hard_and_soft_light

    Hard light in a photograph of Nina Sublatti performing at the Eurovision Song Contest. Hard light comes from a single, usually bright, source, which is relatively small compared to the subject. [2] [3] Photographs taken in such lighting have high contrast and sharply defined shadows. [1] The appearance of the shadow depends on the lighting ...

  6. List of lighting design software - Wikipedia

    en.wikipedia.org/wiki/List_of_Lighting_Design...

    This is a list of lighting design software for use in analyzing photometrics, BIM (Building Information Modeling), and 3D modeling. The software is typically used by importing the structural design via CAD files. Then lighting elements are inserted. And finally, the lighting objects are associated with a photometry via IES files.

  7. Ambient occlusion - Wikipedia

    en.wikipedia.org/wiki/Ambient_occlusion

    In 3D computer graphics, modeling, and animation, ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting. For example, the interior of a tube is typically more occluded (and hence darker) than the exposed outer surfaces, and becomes darker the deeper inside the tube one ...

  8. Bidirectional reflectance distribution function - Wikipedia

    en.wikipedia.org/wiki/Bidirectional_reflectance...

    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 ...

  9. Light fixture - Wikipedia

    en.wikipedia.org/wiki/Light_fixture

    A light fixture (US English), light fitting (UK English), or luminaire is an electrical lighting device containing one or more light sources, such as lamps, and all the accessory components required for its operation to provide illumination to the environment. [1] All light fixtures have a fixture body and one or more lamps.
