GLview Express is a free 3D viewer for presentation and distribution of 3D models and results generated by GLview Inova or the GLview Express Writer.
The product enables full 3D interactivity and high performance graphics, and is the CAE world's equivalent to Adobe Acrobat® Reader.

GLview Express can only read closed format VTF files, which contain the model geometry, scalar/vector results, display attributes and animation settings.
GLview Express is a great marketing and communication tool and is available on Windows, UNIX and Linux platforms.
