Abstract:
This invention provides a projection method with multiple rectangular planes at arbitrary positions to a variable projection center, including: obtaining a user viewpoint position; comparing a horizontal field of view angle between the user viewpoint position and each visual plane with a predetermined range, wherein if the horizontal field of view angle fails to be within the predetermined range, the user viewpoint position is updated to a new user viewpoint position, such that the horizontal field of view angle between the new user viewpoint position and each visual plane is just within the predetermined range; and respectively generating projection channel corresponding to each visual plane based on the user viewpoint position and performing projecting. The technical solution of the present invention can achieve the information interaction between the projection position of the CAVE system and the actual visual position of the user and the processing of the information.

Claim (Index 6):
The projection method according to  claim 1 , wherein the step of updating the user viewpoint position to the new user viewpoint position such that the horizontal field of view angle between the new user viewpoint position and each visual plane is just within the predetermined range comprises:\n acquiring a coordinate of a point on an extension line of a connection line between an original user viewpoint position and a midpoint of a corresponding visual plane as a quasi-position; and if the horizontal field of view angle between the quasi-position and each visual plane falls within the predetermined range and a distance between the quasi-position and the original user viewpoint position is the shortest, taking the quasi-position as the new user viewpoint position.
