OpenVDB

OpenVDB is a software framework used in digital content creation, especially for visual effects and animation. It efficiently stores and manages complex 3D data, like smoke, fire, or fog, by using a grid structure that can represent detailed volumetric information at various resolutions. This allows artists and technical teams to create realistic, high-quality simulations with less computational resources and greater flexibility. OpenVDB's open-source nature also promotes collaboration and innovation within the industry, making it a standard tool for handling volumetric effects in movies, games, and visualizations.
