Method and device for rendering mountain in three-dimensional virtual scene of application program

Abstract

The invention discloses a method and device for rendering a mountain in a three-dimensional virtual scene of an application program. The method comprises the steps: obtaining a three-dimensional model used for manufacturing a target mountain, wherein the three-dimensional model comprises the outer contour and the inner structure of the target mountain; obtaining a two-dimensional height map used for controlling the terrain height in the three-dimensional virtual scene to form the surrounding terrain, wherein the two-dimensional height map comprises a replacement area corresponding to the position of the target mountain, and at least part of the replacement area is set to be in the target color; controlling the terrain height in the three-dimensional virtual scene according to the two-dimensional height map to form a surrounding terrain, and placing a three-dimensional model at a position corresponding to at least part of the replacement area to form a target mountain fused with the surrounding terrain. The method solves the technical problems that in the prior art, transverse modeling constraints of caves and the like cannot be achieved in the virtual mountain landform achieved through a height map, and landform fusion and connection of the virtual mountain landform achieved through engraving software are stiff.

Description

technical field [0001] The present invention relates to the technical field of games, in particular to a method and device for rendering mountains in a three-dimensional virtual scene of an application program. Background technique [0002] In the prior art, the ways to create virtual mountain topography in the game scene mainly include: uplifting the plot to form a mountain topography by adding a height map, or directly stacking mountain models to realize various mountain topography. [0003] However, the mountains realized by using the mountain software through the height map can only be stretched in the vertical direction, and it is technically impossible to realize the horizontal shape constraints such as caves; the virtual mountain terrain output by the model mesh using the engraving software can be placed with the The combination of the surrounding mountains and the ground is relatively rigid, and a natural fusion cannot be achieved. [0004] For the above problems, n...
