The HOOPS 3D Part Viewers are available for the MS Windows platform, either as a standalone or with integrations to either the Parasolid, ACIS or Granite kernels. Each Part Viewer is built using the HOOPS 3D Product Suite from TSA, with special variants which include the modeling kernels mentioned above. The HOOPS components are modular and extensible tools which help developers rapidly deliver world class 2D/3D applications.

These Part Viewers are intended to serve as sample applications which serve as templates for developers licensing one or more of the underlying components In general, the Part Viewers allow the user to:

• Read HSF (HOOPS Stream Format) files as well as VRML, STL and OBJ (Alias|Wavefront) formats.
• Read the XT, SAT or Granite formats (as appropriate)
• Web publish any loaded files via the "Save As HTML" or "Save as HSF" capabilities. HSF is the HOOPS Stream Format at the center of the OpenHSF Initiative.
• Real-time, simultaneous collaboration between multiple users.
• Navigate even the most complex parts in real time via the constant frame rate manipulators.
• Export files in a broad range of vector formats including CGM, EMF and HPGL
• Export data in all major raster formats including JPEG, GIF and BMP.
• Perform visualization operations such as Orbit, Pan, Zoom, etc.
• Move entities within the scene using the high-speed HOOPS "Spriting" algorithm.
• Print, Print Preview and Copy to Clipboard.
