Few materials do not cause diffuse reflection : among these are metals, which do not allow light to enter; gases, liquids, glass, and transparent plastics ( which have a liquid-like amorphous microscopic structure ); lens of an eye.

Diffuse reflection of light from objects ( the technical term for why you can see the color of objects ) is as complicated as the surface of the object; the quality of the reflection has a lot to do with the nature of the surface texture.

In the late 1860s, through the practice of painting light and water " en plein air " ( outdoors ), he and his friend Claude Monet discovered that the color of shadows is not brown or black, but the reflected color of the objects surrounding them, an effect known today as diffuse reflection.

It has been studied in that the average luminosity of a cathode ray tube ( CRT ) diffuse reflection off of a wall can sufficient to reconstruct the signal displayed on the CRT . One greatest strength of this attack is that neither physical access of the medium / device is required, nor line of sight is important.

The "'Lambertian reflectance "'article says that it is used as a model for diffuse reflection, and for most of its mathematics links to the "'Lambert's cosine law "'article which says that blackbodies obey it ( the "'Stefan-Boltzmann law "'article corroborates this ).

"' Polishing "'is the process of creating a smooth and shiny surface by rubbing it or using a chemical action, leaving a surface with a significant specular reflection ( still limited by the index of refraction of the material according to the Fresnel equations . ) In some materials ( such as metals, glasses, black or transparent stones ) polishing is also able to reduce diffuse reflection to minimal values.

The way gradients were used ( e . g . a single radial gradient for the whole surface texture ), the way the edges between pieces were filled with continuous fills, and the use of solid tones in the lettering, suggests to me that someone may have created a full 3D wire frame but then flattened it and painted it in 2D . Actually, it would be pretty hard in general to have a 3D model with a light source and diffuse reflection and have that come up with a vectorized image.
