Rendering in 3D
|A Photorealistic 3D Rendering|
Following on from our previous articles on the 3D Modelling, lighting, materials and textures and animation we now finish our 5 part series with a look at 3D Rendering.
In 3D graphics rendering means the calculation of the final image from the scene that includes models, textures, lights, special effects and cameras. The final image will be a 2D image made of pixels. Utilizing materials, lighting techniques, and renderer's settings one can render multitude of different images from a single 3D scene. Often the goal is to produce realistic rendering, for example in live action movies the goal is to render 3D effects as realistically as possible as it is a cheaper and easier alternative to building sets or hiring extras for a scene.

Cell Shading / NPR Rendering:

Cell Shading is a from of Non-photo realistic rendering (NPR). In contrast to traditional computer graphics, which has focused on photo realism, NPR is inspired by artistic styles such as painting, drawing, technical illustration, and animated cartoons and focuses on enabling a wide variety of expressive styles for digital art. NPR has appeared in movies and video games in the form of "cartoon shading", as well as in architectural illustration and experimental animation.
An example of a modern use of NPR is that of cell-shaded animation as seen above. Another form of NPR is cartoon style rendering means a material / rendering method that produces an image that looks like a hand drawn picture.
