GLScene is an OpenGL based 3D library for Delphi. It provides visual components and objects allowing description and rendering of 3D scenes in an easy, no-hassle, yet powerful manner.

GLScene is not just an OpenGL wrapper or utility library, it has grown to become a set of founding classes for a generic 3D engine with Rapid Application Development in mind. GLScene allows you to quickly design and render 3D scenes without having to learn the intricacies of OpenGL, if you know how to design a TForm, you'll easily master the basic operations of GLScene. The library comes with a large collections of demos showcasing the ease of use, and demonstrating RAD wasn't done at the expense of CPU/GPU horsepower.
