Computational geometry is a branch of computer science and mathematics that focuses on the study of geometric objects and their relationships. It involves algorithms and data structures to solve problems related to shapes, sizes, and spatial properties. Applications include computer graphics, robotics, and geographic information systems (GIS). Researchers in computational geometry develop methods to efficiently process and analyze geometric data. This can involve tasks like finding the shortest path between points, determining intersections between shapes, or optimizing layouts. The field is essential for advancements in technology that require spatial reasoning and manipulation.
