The ``PowerPlant'' demo is a typical factory visualization demo. It demonstrates inView /OpenRT 's ability to efficiently render even complex scenes of millions of individual triangles. Typical applications are the interactive visualization of whole factories, construction sites, of complex models directly out of the CAD data base.
In order to install and run that demo, make sure have first read Section 4.1. Now get the inViewDemo.PowerPlant.tar.bz2 file, and unpack it. You should now have a directory called inViewDemo.PowerPlant. Enter that directory, and call ./rundemo. inView should open. If not, check your configuration.
Note: If you have a machine with more than 1GB of RAM, you may want to call ./rundemo -mmap-immediate instead.
Once inView opens, you see a model of a coal power plant consisting of 12.5 million individual triangles. The model has not been simplified or decore'd in any way, and is rendered at full resolution. As initial view, you should see something like the following image.
Using fly mode and inspect mode to fly around the model then shows view like the following
Instead of only moving inside the scene, inView also allows for some basic editing of the scene by moving parts of the model. To move some part of the model, select it by entering inspect mode (ctrl-i), and shift-leftclicking onto it.
Note: Shift-leftclick in inspect mode is the same as selecting an inspection center. This always automatically selects a new object for transformation.
To move the selected object, press the <tab> key, and drag the mouse while keeping the <tab> key pressed. The mouse interaction (rotating, moving forwards, backwards, and sideways) is the same as during inspect mode, i.e. left button for rotation, middle button for transformation parallel to the image plane, and right button for forward/backward motion.
Go back to the initial view, enter inspect mode (ctr-i), and select a part of the object for transformation. Move the selected object by pressing both the <tab> key and the middle mouse button while moving the mouse around. Moving first one, and then several parts around should look somewhat like
In that way, even the highly complex inner parts like the furnace - consisting of thousands of thin pipes - can be inspected at close detail: Move away all the parts surrounding the furnace, then move closer to inspect it.
Using inView /OpenRT , even as complex (and even more complex, see [6]) models can be rendered interactively without the need for simplification.
