Voreen 2.5: OpenGL Volume Rendering Engine
Voreen is an open source volume rendering engine which allows interactive visualization of volumetric data sets with high flexibility when integrating new visualization techniques. It is implemented as a multi-platform (Windows, Linux, Mac) C++ library using OpenGL and GLSL for GPU-based rendering.

Their render engine is really slow I don’t understand why because it shouldn’t.

Voreen is the fastest GPU volumetric ray-casting engine; it’s best (GPU based) if you need high quality interactive VR. For interactive low quality you may find better VR engine based on old fashion Texture Mapping volume rendering technique.
