3DMLW platform

The 3DMLW platform is an open-source software suite aimed at showing dynamic 3D content. It included its own scripting language for software design, and a format support for 3D models.

3DMLW renderer

The rendering engine uses industry standard OpenGL. It can be plugged into 3DMLW Plug-in Interface and consists of a scene library and a graphics library, which provides an optimized rendering pipeline for the scene library structures. The scene library can be utilized independently for the manipulation or conversion of meshes without rendering them.

3DMLW plug-in interface

The plug-in interface mediates input events and output from host windows (e.g. web browsers) or an independent output window. It is extendible to allow integration into 3rd party software. Native support has been implemented for common web browsers.
