Description:
This piece is from an experimental work and demonstrates the simulation of the muscles of a creature. The main objective is to simulate the movements of a skeletal structure. In this particular piece, a robot in the form of a tiger searches for unknown life on the surface of a planet.
Hardware:
HARDWARE: A multi-microcomputer system LINKS-1 (System
256, System 64 and System 48), frame buffer
(1024 x 1024 pixels x 24 bits/pixels), SONY
BVH-2000 video recorder. The resolution of this
video image is 1024 x 480 pixels.
Software:
SOFTWARE DEVELOPER: A rendering and ray tracing package on the LINKS-1 includes techniques for computing reflec- tion, refraction, shadows, texture mapping, anti-aliasing, atmospheric haze and several lighting effects.

Format: 3:00; 3/4″; sound
Technical notes:
Two 35mm films were made simultaneously of the
front and side views of a real tiger walking.
The data for the coordinates of his joints were
obtained by digitizing pairs of scenes. A new
rendering model, “bio-metaball”, was developed to
represent objects such as muscles. This model is
controlled by the movements of the joints and has
been realized by means of equi-potential surface
techniques.
