A method and apparatus for vertex reconstruction based on terrain cutting, a processor and a terminal are provided. The method includes: position information of a unit block to be removed is acquired, terrain resources in a game scene are cut into multiple terrain chunks, and each terrain chunk is cut into multiple unit blocks; vertex data of at least one adjacent unit block of the unit block to be removed is determined according to the position information; and at least one triangular patch to be rendered is reconstructed according to the vertex data. The present disclosure solves a technical problem that a terrain change mode provided in the related art is limited within a region of a single plane thereby lacking flexibility and realism.
