Abstract

A system and method of procedural generation of graphics corresponding to a plurality of buildings in a three-dimensional virtual environment includes identifying a region in the three- dimensional virtual environment that is enclosed by a plurality of streets within the three- dimensional virtual environment, generating a two-dimensional arrangement of a plurality of tiles within the region, identifying one building segment graphic in the subset of building segment graphics corresponding to each tile based on an array of pseudo-random index values stored in the memory for each tile in the plurality of tiles, and generating a graphical depiction of the three-dimensional virtual environment including a graphical depiction of the plurality of buildings in the region based on the two-dimensional arrangement of the plurality of tiles and the building segment graphic identified for each tile in the plurality of tiles.

Description

technical field [0001] The present disclosure relates generally to the field of computer graphics, and more particularly, to systems and methods for the procedural generation of graphics representing buildings in three-dimensional computer graphics. Background technique [0002] Many modern software applications display three-dimensional representations of virtual environments as part of the user interface. Three-dimensional (3D) graphics are used in a wide range of applications, including video games, simulations, virtual and augmented reality applications, geospatial information applications, and applications for maps and navigation. In many applications, 3D graphics are more useful than two-dimensional (2D) graphics for depicting real-world environments and locations, because normal interactions between humans and the real world occur in three dimensions. [0003] To display three-dimensional graphics, computing systems require geometric information for structures and ot...
