.HSF File

File extension hsf is probably best know for its use for HOOPS Stream format.

The OpenHSF Initiative is effort to establish HOOPS Stream Format (HSF) as a common, open and rich streaming format for sharing visualization data between disparate engineering applications.

HOOPS .hsf file format is an old 1980s and 1990s file format originally created by Ithaca Software of New York State.

OpenHSF represents visualization format geared specifically toward engineering, making it the ideal solution for sharing visual models between applications used within the greater PLM marketplace.

Files with hsf extension can be found as 3D models based on the HOOPS file format which is used for sharing visualization data between disparate engineering applications.

How to open:

Primarly use HOOPS to open and edit *.hsf stream files. But it is likely that more program exists which could be used to work with *.hsf files.

How to convert:

Some 3D translation tools like PolyTrans|CAD+DCC can convert .hsf files to other 3D models.
