OGRE 3D, acronym for Object ‘Oriented Graphics Rendering Engine’, is a free scene-oriented 3D rendering engine, designed to make life easier for (video game) developers, so they can produce environments with 3D graphics in a intuitive.
Many commercial games such as Torchlight, Garshasp, Zombie Driver or Zero Gear have used this tool with very positive results, both at the product quality level and even at the sales level, something that supports the quality of OGRE 3D to some extent.
In terms of performance, OGRE 3D contains practically everything that a private user or a professional studio may need to develop their games, from support for the animation of human skeletons to loading complex textures in different formats, passing through particle composition systems or use of transparent elements.
OGRE 3D is a 3D graphics creation tool that is actively used in some commercial and open source games. From adventures like Venetica (2009) to role-playing games like Torchlight II (2012), many are the games that make use of this technology.
