Does ActiViz 64 work with Visual Studio?
The only limitation is the use of the designer within VisualStudio when targeting the .NET Framework.

Visual Studio is a 32 bits application, therefore 64 bits control does not work and you need the 32 bits version of ActiViz when using the designer within Visual Studio.
Usually, the 32 bits version is used to design and the 64 bits version is used for the final compilation.

When using an ActiViz version targeting .NET Core, both 64 bits and 32 bits work fine in the designer.

What are ActiViz recent improvements?

ActiViz 9.2 release implements significant improvements as well as numerous features related to rendering, filtering and I/O, including:
– Support for multiple .NET versions from .NET Framework 4.0 to .NET 7
– Enhanced support for reading and writing DICOM images
– Support for the Hololens 2 using OpenXR remoting
– Enhanced volume rendering using the new scattering model
