Abstract:
New York Institute of Technology is involved in producing
animated films with very good image quality. We have extensive
computer graphics facilities devoted solely to animation. This
includes a number of full-color frame buffers and two line-drawing
systems, together with a high-quality film recorder, video tape, and
disk equipment. We also maintain a strong association with a
conventional animation studio.
Our images are created at high resolution (1500 lines). In order
to achieve good quality we must use hidden surface algorithms that
apply anti-staircasing techniques at high resolution; we have used
Fourier window filtering for this purpose. We have taken great care
to ensure film transmittance is exactly proportional to intensity
values. In trying to build production animation systems, we have
found the problem of manipulating large numbers of images, in excess
of 100,000, to be one of our main problems.
Pictures produced at NYIT will be shown
