You must specify a valid Visualize license in your application code in order to use the Visualize product. The license key is a character sequence either directly provided by Tech Soft 3D or generated using the "Generate Key" button located on the Visualize downloads page in the Developer Zone.

If an invalid or expired license is set, your Visualize-based application will exit when Visualize attempts to start. If you are using a time-bound evaluation license, the Visualize viewport will display a small piece of text indicating that it's an evaluation license, and also display the number of days remaining until expiration.

Setting the License

The license should be compiled into your application via the HPS::World object, which initializes HOOPS Visualize. In C++, the license is delivered in a file called hoops_license.h. In C#, the license is set in a file called hoops_license.cs. Paste your license string into the HPS::World constructor.

World world("[your unique license string]");
World world = new World("[your unique license string]");

Alternatively, users have the option of replacing the existing hoops_license.h or hoops_license.cs files in the include directory with the one from the Developer Zone, and passing the defined variable HOOPS_LICENSE to the HPS::World constructor.

The various samples and sandbox projects already reference hoops_license.h or hoops_license.cs for convenience, and you can simply copy your license file to your Visualize installation's include directory.

IMPORTANT: Your application must instantiate the HPS::World object before interacting with Visualize, and the object must stay in scope as long as the application continues to use Visualize. For C# users, a static HPS::World object at the module level is recommended, due to the unpredictable nature of the .NET garbage collector.
