Background: Physics and Math of Shading

  title={Background: Physics and Math of Shading},
  author={Naty Hoffman},
Light is an electromagnetic transverse wave, which means that it oscillates in directions perpendicular to its propagation (see Figure 1). Since it is a wave, light is characterized by its wavelength—the distance from peak to peak. Electromagnetic wavelengths cover a very wide range but only a tiny part of this range (about 400 to 700 nanometers) is visible to humans and thus of interest for shading (see Figure 2). The effect matter has on light is defined by a property called the refractive… Expand
An Introduction to BRDF Models

Real Shading in Unreal Engine 4 by
About a year ago, Epic decided to invest some time in improving their shading model and embrace a more physically based material workflow, and with perfect timing came Disney’s presentation concerning their physically based shading and material model used for Wreck-It Ralph. Expand
Plasticine shading
A new shading model is presented which is based on the true physical properties of plasticine and it is shown that this new model represents the material approximately 20% more accurately than other existing state of the art surface shaders. Expand

A comprehensive physical model for light reflection
A new general reflectance model for computer graphics is presented and provides a smooth transition from diffuse-like to specular reflection as the wavelength and incidence angle are increased or the surface roughness is decreased. Expand
