A scene formed by 27 spheres with material “Glossy” rendered with “Cycles”, the rendering engine that incorporates “Blender”.
The image has been calculated 200 integration steps.
Clicking on the main image is obtained in resolution wallpaper 1280 x 1024.
Another “shaders” incorporating “Cycles” one Blender es “Glass”. Simulate glass and crystals, and other transparent surfaces,
The crystal is a medium that allows the passage of light (translucent) modifying its trajectory. It also reflects the light creating high gloss specular effects.
The lighting of a scene primarily used diffusion and reflection effects.
We have seen the basic shader using Cycles, called "diffuse", which is based on the model of Lambert or Oren-Nayar, based on the value that is used for the parameter "Roughness" ( 0 = Lambertian). This calculation model simulates the dispersion or diffusion of light on the material, but does not consider the effects of specular reflection that are associated with the model called “Glossy”.
Upon visual introduction to shaders saying we introduced the concept:
Synthetic images, as we are calculating with Blender, are rendered with different types of algorithms; results vary the final representation of the objects in the scene.
The mathematical models which allow a synthetic image are grouped into what is called “Shaders” the Shader.
