To make
visible; to draw. The term comes from the graphics
world where a rendering is an artist's drawing of
what a new structure would look like. In
computer-aided design (CAD), a rendering is a
particular view of a 3D model that has been
converted into a realistic image. It includes basic
lighting as well as more sophisticated effects that
simulate shadows, reflection and refraction. It may
also include the application of textures to the
surfaces
There are new techniques such as
photo-realistic visualizations in 3-D that offers
more flexibility and efficiency.3-D photorealistic
rendering can be produced within few weeks or even
few days. If something can be imagined and put on a
paper as a basic sketch or detailed drawings,
then this design can be translated into
photo-realistic visual such as
3-D rendering
or even full blown walk-through animation.
