Visualization of the Boeing 777

Switch vs. Intel's Boeing demo

Switch:

• Advantages
• Switch will display the entire dataset at once, offering a global view of all the details.
  
• The level of detail can be controlled by maintaining a pixels of error metric. This helps for quick navigation of the model while maintaining a basic global view of it.
  
• GLVU based renderer allows easy navigation of any part of the model.
  

• Disadvantages
• Currently, textured objects are not available and it is very difficult to color a model of this complexity, so it is not as visually appealing
  
• Very slow to load (on the order of 2 hrs from hitting enter to the first image)
  
• Long preprocessing time (For the entire model, it took about one month of computation time on a Intel Itanium processor)
  

Intel:

• Advantages
• This system uses a very nice textured Boeing 777 "shell" and good coloring to display the model.
  
• The shell can be rendered easily at very quick rates, allowing for faster navigation.
  
• When viewing a particular component, the shell offers a good reference point of where the component is located relative to the general shape of the airplane.
  
• A nice GUI is in place, especially for level of detail control

• Disadvantages
• The primary disadvantage is that the entire model is not loaded at once. When the user wants to view a specific section, the viewer follows a precomputed path and then displays that section. This does takes away from the global view.
• Currently, only a small number of objects can be shown in detail.
  

Boeing 777 Images from Switch

File/Short description	Preview
Boeing_front_full.png This image is the front section from a more complete model of the Boeing 777.
full_boeing_front.png This is another image from the complete model. It shows the front section of the Boeing.
full_boeing_engine.png A view of the left engine from under the body of the Boeing 777.
full_boeing_engine_closer.png A little bit closer to the engine.
engine.png Zoomed in view of the engine
engine_closer.png Even more zoomed in.
boeing1.png This image is from a "small" portion of the model. It represents about 130 million polygons from various parts. The view is from the left side of the plane.
boeing2.png This is essentially the same as the previous image, but with slightly brighter colors.
boeing3.png This is a view of the underside of the left wing. Like the previous two, it is not the complete model but a smaller portion. I think the green object is a piece which holds the engine, but unfortunately, the engine was not included in this portion of the model.
boeing4.png This is a slightly zoomed in view of the previous image.
boeing5.png This is an image of a 130 million polygon portion of the Boeing 777. It shows several large components, but is clearly missing others as well.
boeing6.png This view shows the underbelly of the airplane.
boeing7.png This is a zoomed in view of the underbelly from the previous image. Again, this is only a 130 million polygon portion, which is why there is a large "hole" between the hull and the inner structure.
boeing8.png This view is from moving into the hole described in the previous image. The lattice is some of the inner structure and we're looking along it towards what seems like some sort of cargo area.
boeing10.png This is a view of the tail section of the airplane.
boeing11.png A zoomed in view from the other side of the tail section.
new1.png This shows some of the interior of the airplane. The purple objects are a couple of chairs, while the cyan parts are pieces of the planes inner structure.
new2.png This is another view of the underbelly, but viewed from beneath the nose. We're not quite sure what the conic looking object is. From what we can tell, it came with our version of the model.
new3.png A zoomed in view of the front of the airplane. Once again, some pieces are missing due to this being only a portion of the model.
new4.png A further zoomed in view of the nose. In this view, we get a better view of some of the internal components in this part of the airplane.

Images from the Intel Boeing 777 demo

File/Short description	Preview
intelboeing.JPG This is from the opening view of the Boeing with the Intel render. As you can see, they use a nice textured model which is quick and simple to render. This helps for a much more visually appealing view.
intelboeing2.JPG This is the underbelly of the Boeing model. Again, the textured objects make for a much nicer and possibly more meaningful representation of the data.
intelboeing3.JPG This shows one of the zoomed in features from Intel's demo. This is a close up of the details of the landing gear. Like the Switch version, this part was not textured. But, in this image you can see a small part of the Boeing silhouette that is left when in the detailed component view.
intelboeing4.JPG This is a zoomed in view of a control box on the landing gear. The Intel viewer does support navigation of the detailed components.
intelboeing5.JPG This is a piece of one of the engines.
intelboeing6.JPG This is another image of a detailed component from the Intel Boeing demo.
