Abstract:
An image generating method, includes: establishing a 3D scene model that includes a virtual 3D object, a virtual display screen and at least one sight point set; determining a plurality of intersection points between a plurality of virtual light paths from each sight point to a plurality of virtual object points on the surface of the virtual three dimensional object and the virtual display screen, all virtual light paths {l k 1 , l k 2 , . . . , l k S } corresponding to the virtual object point T k  intersect at the virtual object point T k ; wherein, 1≤k≤n, 1≤i≤S, S is the total number of established sight points, and the plurality of virtual object points are all located within the viewing angle range of the virtual display screen; forming S frames of rendered images, including: determining color parameters of a plurality of intersection points on the virtual display screen to obtain the i th  rendered image.

Claim (Index 7):
The device of  claim 6 , wherein each of the sight point sets includes of one emitting sight point and one backtracking sight point;\n the determining module comprises: a light ray simulation unit configured to simulating a plurality of first light rays emitted from the emitting sight point to a surface of the virtual three-dimensional object via the virtual display screen in a viewing angle range of the virtual display screen; an intersection point obtaining unit configured to obtain first intersection points between the plurality of first light rays and the virtual display screen, the intersection points between the first light rays and the surface of the virtual three-dimensional object being virtual object points {T 1 , T 2 , . . . , T n }; the light ray simulation unit being further configured to simulate emitting second light rays from a plurality of the virtual object points {T 1 , T 2 , . . . , T n } to the backtracking sight point; the intersection point obtaining unit being further configured to obtain second intersection points between a plurality of the second light rays and the virtual display screen.
