HOOPS Communicator

HOOPS Communicator 2023 Service Pack 2 introduces improvements for SOLIDWORKS decals including enhanced scaling, offset, and clamping capabilities. Additionally, HOOPS Communicator 2023 SP2 now offers support for label projection mapping, effectively preventing distortion when projecting decals onto objects, and ensuring accurate alignment with the object's surface. This release also provides three distinct transparency modes for SOLIDWORKS decals.

HOOPS Communicator 2023 SP2 introduces increased support for cloud storage allowing users to write their own classes that inherit from abstract base classes to customize I/O. This functionality can be useful for users looking to do their Stream Cache I/O over WebSocket, another protocol, or lay your files out in a way that would make them normally unreadable by the default Stream Cache filesystem methods.
