XGRT - Extensible Graphics Toolkit

Summary

XGRT is an object oriented software system for rapid prototyping of graphics applications that has been used in several research projects. It is implemented in C++ based on the platform independent  QT4 GUI library. The software is open source (GPL) and can be downloaded at the  XGRT download page. The system consists of an object oriented base layer, which is application independend, and an interactive 3D editor. The 3D editor currently provides the following features

• Real-time rendering and editing of arbitrarily large point clouds, size is only limited by available hard disk space (out-of-core visualization and editing).
• Modular scene graph architecture that supports point clouds, triangle meshes, and volume data.
• Supports the most common graphics exchange formats (VRML, OBJ, SMF, PLY, OFF, BMP, JPG, PNG, universal configurable ASCII & Binary importer, ASCII export).
• Attribute channel architecture: Arbitrary point / vertex / face / volume attributes, run-time configurable.
• Flexible rendering architecture: Run-time programmable hardware shaders (shader input is bindable to user attribute channels).
• Hardware accelerated global illumination rendering: Ambient occlusion, shadow mapping, environment mapping.

 The system is highly modular and extensible. The main focus is rapid prototyping of research ideas, the system has not been designed as an end user application. It comes with  no support and no warrenties.
