15.1 RENDERING FOR VIRTUAL RE ALITY
15.1.1 Introduction
Irrespective of their final use, all virtual reality systems are based on the simulation
of a task using computer resources (calculation, display, interaction, etc.). It can be a
task of exploration, learning, designing, etc. More precisely, it involves providing the
user’s brain with information resulting from digital data and simulating the context of
the task to be performed.
The first sense involved is the vision; in fact, a large amount of information used
by the human brain to perceive his environment
