Computer software designers have invented a virtual stuntman.

Unlike virtual actors which have to be generated frame by frame, these computerised cast members respond to real physical forces.

The programs have sensors which detect gravity, friction and impact with other objects in any given situation.

New Scientist reports that its developer Petros Faloutsos, of the University of California in Los Angeles, says they can perform complex yet realistic feats, without anyone risking their lives.

Each 'stunt artist' is a properly jointed skeleton figure which can be dressed to look like a real member of a film's cast.

Faloutsos's big breakthrough was his design for a program which co-ordinates all the other 'controller programmes' needed to run virtual actors.

It also looks at the effects of the virtual environment on each of the character's joints and limbs, and the effects they have on each other.

It even performs instinctive reactions, like extending the hands to protect itself while falling.
