WebbIf we want to simulate several types of objects in OpenGL we have to define material properties specific to each surface. In the previous chapter we defined an object and light color to define the visual output of the object, combined with an ambient and specular intensity component. When describing a surface we can define a material color for ... parivahan searchWebbAnother, a bit more realistic, lighting model is the Blinn-Phong model that calculates the specular term somewhat differently.
