Luminair itself does not offer a 3D visualizer, but you can use it with any 3rd party lighting visualizer that supports control via Art-Net or sACN. Some examples would be software like Cast WYSIWYG, Capture Polar, ESP Vision, Light Converse, etc.

As long as the 3d visualizer software supports Art-Net or sACN, you wouldn't need an additional interface. Luminair would send the control data directly to the 3D viz software over the local network.
