For example, the first image frame is the 1 st frame in the image sequence in which the virtual three-dimensional model is displayed, and the second image frame is the 11 th frame in the image sequence. When the display screen of the graphical user interface of the client is switched from the first image frame to the second image frame, the texture (i.e., the light effect expression texture) of the target area of the virtual three-dimensional model needs to be synchronously adjusted, so that the texture change of the target area follows the change of the display screen, and the dynamic reality and fluency of the virtual three-dimensional model are ensured.

Taking ray tracing adjustments made to the virtual character model as shown in fig. 5 as an example, fig. 6 is a schematic diagram of ray tracing results of an alternative virtual three-dimensional model according to one embodiment of the application. The virtual character model shown in fig. 5 corresponds to a first image frame, the virtual character model shown in fig. 6 corresponds to a second image frame, and model vertices corresponding to a circular target area (i.e., a circular area on the forehead) of the virtual character model shown in fig. 5 are obtained, wherein the model vertices may be vertices on the virtual character model closest to the center of the circular target area; then, the display position (in the screen space) of the model vertex in the second image frame shown in fig. 6 is determined using the coordinate position (in the model space) of the model vertex, and the display position is taken as the center position of the circular target area of the virtual character model corresponding to the second image frame. That is, the ray tracing adjustment method of the virtual three-dimensional model provided by the application is based on the ray tracing adjustment of the model vertexes of the virtual three-dimensional model, can realize three-dimensional tracing, can trace the model vertexes which are shielded after the model rotates on a two-dimensional display interface, and solves the problems that the shielded points cannot be traced and the tracing effect is poor due to the adoption of two-dimensional view port tracing in the prior art.
