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 8):
The projection method according to  claim 7 , further comprising:\n taking each visual plane as a corresponding initial projection surface for the user viewpoint position to each visual plane; successively calculating values of the lengths of four sides of a projection space according to a position of the initial projection surface; determining a user viewpoint plane based on the user viewpoint position and a directed distance from the user viewpoint position to each visual platform along a projection direction; taking a nearest plane distance from the user viewpoint plane to each visual plane as a distance between the user viewpoint plane and a near clip plane of a respective visual plane; and taking a farthest plane distance from the user viewpoint plane to each visual plane as a distance between the user viewpoint plane and a far clip plane of the respective visual plane.
