In Windows Application BoneLab 2, a new 3D model management technique for visual dissection of a complex 3d model has been implemented. All parts of an anatomical model with a high number of components are displayed in small tile windows, corresponding to a high number of OpenGL viewports. A subsection of the full model can be quickly assembled via tile picking selection. The resulting subsection of the model will be automatically sized and focused. Free Demo program BoneLab 2 Demo is available for download.
