METHOD AND SYSTEM OF REMOVING INVISIBLE SURFACES OF A THREE-DIMENSIONAL SCENE Russian patent published in 2019 - IPC G06T15/40 

FIELD: information technology.

SUBSTANCE: present invention relates to computer graphics. Method for removing invisible surfaces of a three-dimensional scene includes: obtaining on the server of original data on the objects of the three-dimensional scene and their hierarchy from the data exchange channel; receiving on the server of data on the current position of a camera relatively to the scene from the data exchange channel; formation of a register of all three-dimensional scene objects for rendering, in which each object is represented by its unique identifier; implementation on the server of primary culling of three-dimensional objects by the method of clipping on the viewing pyramid; excluding from the registry on the server overlapping three-dimensional objects that also do not require rendering, by sequentially starting two passes of simultaneous drawing of all objects, and on the first pass a minimum z-depth map is created by running simultaneous drawing of all registry objects on the server; second pass defines for each of the objects the number of fragments in which it is visible by running a repeated simultaneous drawing of all objects on the server.

EFFECT: improved performance of the process of drawing a three-dimensional scene.
