Computer graphics questions

  • Features of computer graphics

    Vector graphics and Raster graphics are the two main types of computer graphics.
    Vector graphics use mathematical equations to create images, which means that the image remains sharp and clear even when it's resized.
    It's mostly used for logos, illustrations, and text..

  • How computer graphics are useful these days?

    Today, computer graphics is a core technology in digital photography, film, video games, digital art, cell phone and computer displays, and many specialized applications.
    A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by computer graphics hardware..

A timewarp is a tool for manipulating the temporal dimension in a hierarchically described 3D computer animation system.
The term was coined by Jeff Smith and Karen Drewery in 1991.
Continuous curves that are normally applied to parametric modeling and rendering attributes are instead applied to the local clock value, which effectively remaps the flow of global time within the context of the subsection of the model to which the curves are applied.
The tool was first developed to assist animators in making minor adjustments to subsections of animated scenes that might employ dozens of related interpolation curves.
Rather than adjust the timing of every curve within the subsection, a timewarp curve can be applied to the model section in question, adjusting the flow of time itself for that element, with respect to the timing of the other, unaffected elements.
