Rendering/image synthesis is the process of creating a two or three-dimensional image from a model using application programs. Rendering is primarily used in architecture, video games and animated films, as well as in simulators, television special effects and design visualization. The techniques and features used differ depending on the scope of the project. Rendering helps to increase design efficiency and reduce costs. Rendering is a term that refers to the automated process of creating digital images of three-dimensional models using specialized software. These photos imitate the photorealistic environment, materials, lighting, and objects seen in a project or 3D model. Rendering is also a term that refers to a computer-generated image that is created using three-dimensional modelling of project data. The geometric model is then covered with graphics (textures) and colors that match those of the actual materials and can be illuminated with natural or artificial light sources. When rendering settings are precisely tailored to natural conditions, the texture quality and range of views can be described as photorealistic.
