A modern desktop browser and recent hardware is required, and a broadband connection is recommended.
Directions for using the 3D viewer once it has loaded:
Left mouse+move=rotate Right mouse+move=pan Middle mouse=zoom in,out
The above 3D models are computationally intensive to display. Older machines will be strained by the requirements. As a result, some machines will display a lower resolution model. If this happens, consider viewing on a faster computer. You can also view these models in full screen by clicking the opposing arrows button on the bottom right of the player.
If by rotating/panning/zooming the camera in a way you can’t see the vent anymore, double click anywhere in the player area. The vent will reappear.
