The codebase covers a broad surface of capabiliti

RecastNavigation is a navigation mesh toolset and game AI pathfinding library used to generate and query walkable surfaces in 3D environments. It functions as a runtime navigation mesh generator and spatial query library, transforming raw 3D geometry into simplified surfaces to enable AI movement. The project includes a crowd simulation engine that manages steering and collision avoidance for large numbers of agents. It provides capabilities for group movement coordination and the simulation of many agents simultaneously using scalable navigation techniques. The system covers mesh generation

meshoptimizer is a 3D mesh optimization library designed to compress geometry and animation data, reduce memory usage, and improve rendering performance. It functions as a geometry simplification tool, a mesh compression codec, and a utility for preparing data for mesh shaders and raytracing acceleration. The library provides specialized toolsets for partitioning meshes into clusters and meshlets to optimize hardware-accelerated rendering pipelines. It also includes helpers for generating opacity micromaps and spatial clusters to increase the speed of hardware ray-triangle intersection tests.

A lightweight, easy-to-use, and efficient library for processing and rendering 3D data (C++ & Python)

Collision detection is essential for realistic physical interactions in video games and computer animation. In order to ensure real-time interactivity with the player/user, video game and 3D modeling software developers usually approximate the 3D models composing the scene (e.g. animated…

The Polygon Mesh Processing Library is a modern C++ open-source library for processing and visualizing polygon surface meshes. Its main features are:

A generic programming header only C++ library for processing polygonal and polyhedral meshes

PolyPartition is a lightweight C++ library for polygon partition and triangulation. PolyPartition implements multiple algorithms for both convex partitioning and triangulation. Different algorithms produce different quality of results (and their complexity varies accordingly). The implemented…

This project implements the seam-aware decimation portion of our SIGGRAPH Asia 2017 paper Seamless: Seam erasure and seam-aware decoupling of shape from mesh resolution. Seam-aware decimater simplifies a mesh while preserving its UV's boundary. It allows the same texture to be used across all…

When graphics programmers face the problem of creating a mesh for a sphere, trade-offs must be made between quality and construction, memory and rendering costs. This document introduces four different methods and analyzes their characteristics and compares them allowing programmers to make an…
