7.6.2.1 Design
Because of the huge investment most shows make in visual effects, it is
critical to make sure your CG i ts the depth, geometry and color of the
live-action show. Equally as important, the CG needs to have the desired
level of realism (or non-realism) that conveys the story as intended by the
show's authors. 3D expertise can be valuable here to help the team determine
which visual effects techniques will give the most impact given the resources
available to the show. Visual effects should take advantage of Z-Space while
also minimizing the chance for issues such as edge violations and excessive
positive or negative parallax.
7.6.2.2 Rotoscoping/Painting
Roto/paint can be used for planned as well as unplanned imagery i xes,
like painting out rigging, errant microphones, or lights and incautious crew
members. Other activities include adding, eliminating or enhancing one or
more visual elements in a scene because of an unplanned event in physical
production or because the elements are replaced by CG. Teams must take
extreme care to avoid introducing additional issues (such as interference
between CG elements and live action scene elements) in the effort to provide
elements.
7.6.2.3 Compositing
Compositing is the workhorse of the Visual Effects workl ow in 3D just as
it is in 2D. Compositing tool operators need to be aware of the look and
feel of the live-action show to make sure their creative decisions maintain
viewer comfort and story continuity.
7.6.2.4 CG Modeling, Rigging, Animating, Lighting
The primary challenge of CG creation in 3D is properly simulating the
“roundness” or apparent shape of CG elements to match the roundness of
elements in the live action scene.
7.6.3 Tools
There are hundreds of visual effects tools available in the areas of modeling,
simulation, rigging, animating, lighting, shading, rendering and compositing.
