ActiViz in Use


How can I get ActiViz
The pre-compiled binary packages are available with our professional support contract.
We also propose one time binaries without support. Please contact us for more information.
What type of license is ActiViz under?
ActiViz is licensed under a BSD license, a family of permissive free software licenses, imposing minimal restrictions on the redistribution of covered software. Therefore, your ActiViz developments can be integrated into commercial applications.
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?
