2. Reflection (computer graphics) - Wikipedia

   en.wikipedia.org/wiki/Reflection_(computer_graphics)

   - A polished reflection is an undisturbed reflection, like a mirror or chrome surface. Blurry - A blurry reflection means that tiny random bumps on the surface of the material causes the reflection to be blurry. Metallic - A reflection is metallic if the highlights and reflections retain the color of the reflective object. Glossy

3. Specularity - Wikipedia

   en.wikipedia.org/wiki/Specularity

   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 modeled as specular highlights.

4. Specular highlight - Wikipedia

   en.wikipedia.org/wiki/Specular_highlight

   Specular highlights on a pair of spheres. A specular highlight is the bright spot of light that appears on shiny objects when illuminated (for example, see image on right). ). Specular highlights are important in 3D computer graphics, as they provide a strong visual cue for the shape of an object and its location with respect to light sources in the

5. Ray tracing (graphics) - Wikipedia

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

   A reflection ray is traced in the mirror-reflection direction. The closest object it intersects is what will be seen in the reflection. A refraction ray traveling through transparent material works similarly, with the addition that a refractive ray could be entering or exiting a material.

6. 3D rendering - Wikipedia

   en.wikipedia.org/wiki/3D_rendering

   Modern 3D computer graphics rely heavily on a simplified reflection model called the Phong reflection model (not to be confused with Phong shading). In the refraction of light, an important concept is the refractive index ; in most 3D programming implementations, the term for this value is "index of refraction" (usually shortened to IOR).

7. Reflection mapping - Wikipedia

   en.wikipedia.org/wiki/Reflection_mapping

   An environment texture mapped onto models of spoons, to give the illusion that they are reflecting the world around them. In computer graphics, reflection mapping or environment mapping [1] [2] [3] is an efficient image-based lighting technique for approximating the appearance of a reflective surface by means of a precomputed texture.
