The term "3D rendering" is the catchphrase for the overall process by which animators use sophisticated computer software to create an image from an artificial model that has height, length, and depth. Animators can use the rendering to develop a single human or cartoon figure or object, and the rendering can also contribute lighting, shadows, textures, and shading to the figure. Once rendered, the object can be moved about along all 3D axes, allowing the animator to see it in complete dimensions.
When you learn animation, rendering is typically the final step in the pipeline of transformation of original geometric objects into a 3D display. In the first step, a model is created using primitive shapes. The shapes can be captured from a live image or created by an illustrator -- that is, by hand or by illustration software.
In the second step, the animator uses rendering software to manipulate the 2D image in overall size and camera angle. You'll use detailed computer software to assign complete dimensions to the object and thus determine how it will be lighted and how it will retain proportions in space.
The rendering stage involves tracing the original, enabling the computerized transformation of the model, using precise calculations to adjust the image as it is manipulated. Rendering ads direct as well as indirect illumination, reflections, shadows, motion blurs, artistic or photorealistic morphing.
The final result is a realistic or imaginary 3D object or animated character that can be used in training simulators, computer games, or entertainment film and video.
