Blocking is an animation technique in which key poses are created to establish timing and placement of characters and props in a given scene or shot. [1] This technique is most commonly used in 3D computer animation, where it is sometimes referred to as Stepped animation.
Skeletal animation or rigging is a technique in computer animation in which a character (or other articulated object) is represented in two parts: a polygonal or parametric mesh representation of the surface of the object, and a hierarchical set of interconnected parts (called joints or bones, and collectively forming the skeleton), a virtual ...
An example of computer animation which is produced from the "motion capture" techniqueComputer animation is the process used for digitally generating moving images. The more general term computer-generated imagery (CGI) encompasses both still images and moving images, while computer animation only refers to moving images.
Z-fighting which cannot be entirely eliminated in this manner is often resolved by the use of a stencil buffer, or by applying a post-transformation screen space z-buffer offset to one polygon which does not affect the projected shape on screen but does affect the z-buffer value to eliminate the overlap during pixel interpolation and comparison ...

If multiple surfaces face towards the camera, then additional use of methods such as Z-buffering or the Painter's algorithm may be necessary to ensure the correct surface is rendered. Back-face culling is typically quite a cheap test, only requiring a dot product to be calculated, and so it is often used as a step in the graphical pipeline that ...
Offline rendering can use a slower and higher-quality renderer. Interactive applications such as games must primarily use real-time rendering, although they may incorporate pre-rendered content. Rendering can produce images of scenes or objects defined using coordinates in 3D space, seen from a particular viewpoint.
