Classification: CPC G | IPC G

Claim 3:
4. The method according to claim 1, wherein the to-be-processed vertex data is vertex data in a local coordinate system, and the processing, by the CPU, of the to-be-processed vertex data to obtain the vertex data within the field of view of the user comprises:
performing, by the CPU, coordinate conversion on the vertex data in the local coordinate system based on auxiliary data to obtain vertex data in a clip coordinate system, wherein the auxiliary data comprises a transformation matrix for performing coordinate transformation on the vertex data in the local coordinate system; and
performing, by the CPU, clipping and removal operations on the vertex data in the clip coordinate system to obtain the vertex data within the field of view of the user.
