Computer graphics lighting refers to the simulation of light in computer graphics. Lighting is the technology of illuminating an area, usually by artificial sources such as a lamp or flashlight. Lighting design is concerned with illumination in different settings, such as architectural lighting and theatrical lighting. Lighting plays important role in 3D animation because it convinces the audience that the story is believable. Without great lighting, even a fantastic 3D model can end up looking flat and unconvincing in the final image. You can look for animation courses in Kolkata which will teach you these aspects of animation with in-depth detailing and complete professionalism.
Shading refers to depicting depth perception in 3D models or illustrations by varying levels of darkness. This is a very important module in the animation curriculum. In computer graphics, shading refers to the process of altering the color of an object/surface/polygon in the 3D scene, based on its angle to lights and its distance from lights to create a photorealistic effect. The program shader is used for shading in the process of 3D animation. Before characters are put forward in fully fledged format you need to shade a draft of it. Shading is one of the key steps that one will need to take.
3D rendering is the 3D computer graphics process of automatically converting 3D wire frame models into 2D images with 3D photorealistic effects or non-photorealistic rendering on a computer. Rendering is the final process of creating the actual 2D image or animation from the prepared scene. This can be compared to taking a photo or filming the scene after the setup is finished in real life. 3D rendering is not very different to that of 2D rendering however there are significant changes that need to be kept in mind while making the transition from 2D to 3D. For complete point-to-point detailing you need to take up animation courses in Kolkata which will efficiently help you to master the craft.
