Method and apparatus for vertex reconstruction based on terrain cutting, processor and terminal

A non-transitory storage medium, comprising a stored program, wherein when the stored program is run, a device where the storage medium is located is controlled to perform the method for vertex reconstruction based on terrain cutting as follows:

• acquiring position information of a unit block to be removed, terrain resources in a game scene being cut into a plurality of terrain chunks, and each terrain chunk being cut into a plurality of unit blocks;
• determining vertex data of at least one adjacent unit block of the unit block to be removed according to the position information;
• and
• reconstructing at least one triangular patch to be rendered according to the vertex data;
• wherein acquiring the position information of the unit block to be removed comprises:
• acquiring three-dimensional coordinates of a collision point where an attack trajectory of a game character intersects with a collider of the unit block to be removed, the three-dimensional coordinates comprising:
• a first coordinate and a second coordinate in a horizontal direction, and a third coordinate in a vertical height direction;
• extracting a volume from a terrain chunk where the collision point is located according to the first coordinate and the second coordinate, the volume comprising:
• the unit block to be removed, a first unit block adjacent to an upper surface of the unit block to be removed, and a second unit block adjacent to a lower surface of the unit block to be removed;
• cutting the volume in half to obtain a first cutting volume and a second cutting volume;
• and determining the position information from the first cutting volume and the second cutting volume respectively according to the third coordinate.
