What is Graphics Rendering in Computer Graphics?

Computer generated images by default render the entire scene in perfect focus. The desire to render the world around us is common to many applications. As part of this ‘virtual world’ it is natural to include representations of humans. A realistic visual approximation of a human requires a polygon mesh of significant complexity, especially as it has to be sufficiently tessellated to allow smooth deformations of the model. Image-based modeling and rendering techniques have recently received much attention as a powerful alternative to traditional geometry-based techniques for image synthesis. Instead of geometric primitives, a collection of sample images are used to render novel views. Definition of Rendering Graphics Graphics Rendering is the process of generating an image from a model, by means of a software program. The model is a description of three dimensional objects in a strictly defined language or data structure. It would contain geometry, viewpoint, texture and lighting information. The image is a digital image or raster graphics image. The term may be by analogy with an “artist’s rendering” of a scene. ‘Rendering’ is also used to describe the process of calculating effects in a video editing file to produce final video output. It is one of…
