Formula of Radiosity Rendering
The radiosity equation or formula is one of the fundamental formulas which is used in radiosity rendering this formula is used to compute the distribution of lights within a particular scene.
This formula mathematically describes how the radiosity of each surface patch is directly influenced by the emission of light from that patch the reflectivity on the material and the incoming light from other neighbour patches. the formula for radiosity rendering can be represented as follows:
Where,
Bi is used to represent the radiosity of patch i.
Ei is used to represent the emitted radiosity of patch i.
ρi is used to represent the reflectivity of patch i.
Fij is used to represent the form factor between patches i and j.
η is the total number of patches in the scene.
Radiosity Rendering in Computer Graphics
Rendering is the process of generating images which look realistic, these renderings can be based on either 2D rendering or 3D and computer graphics are used when we want to manipulate a set of images in the form of pixels to show to computer devices. Computer graphics is used in many digital types of photography, film, entertainment, and other electronic gadgets.
In this article, we will understand the radiosity rendering in computer graphics in depth.
