Intensity in computer graphics

WebA (to me) similar concept is intensity which is the amount of power per angle. Again, for a sphere with a point light at the center, this is I = Φ 4 π r 2 with the unit [ W s r] (watt over steradian) Now, the book defines radiance for a point p as L = d Φ d ω d A ⊥ in units [ … WebIn the production of computer generated pictures of three-dimensional objects, one stage of the calculation is the determination of the intensity of a given object once its visibility has been established. This is typically done by modeling the surface as a perfect diffuser, sometimes with a specular component added for the simulation of hilights. This […]
