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 operation of TGLScene.
GLScene includes more than 40 (final) components and a variety of founding classes. The library comes with a set of more than 30 demos showcasing the ease of use and demonstrating RAD wasn't done at the expense of CPU horsepower. Advanced demos and samples can be found in the GLScene site.

The GLScene Sound System allows positionnal 3D audio via low-level APIs like FMOD and BASS.

• Delphi 5 : install the GLScene5.dpk as usual, if you want positionnal sound support via FMOD/BASS, also install the GLSS_FMOD5.dpk/GLSS_BASS5.dpk package
• Delphi 4 : install the GLScene4.dpk as usual, if you want positionnal sound support via FMOD/BASS, also install the GLSS_FMOD4.dpk/GLSS_BASS4.dpk package

GLScene does not support Delphi 3 and previous, and was never compiled/used/tested under CPPBuilder.

If you installed a previous version, make sure no files of the previous version remains, some file may have been renamed, moved or removed in between versions. Don't forget to check for stray previous-version ".BPL" files in your system directories if you placed any there.

Some Delphi units, API headers and DLLs are included in the GLScene package for convenience but are not part of GLScene, may use different licensing scheme and have different copyight owners, such files have an explicit notice attached to them or placed in their directory.
