Three-Dimensional Realistic Devices

Apart from the aforementioned components, the HO FDTD methodology is applied to various modern waveguide systems whose specialized function requires precise and inexpensive discretizations. Moreover, the need for fast and credible design estimates opts for relatively short simulations without sacrificing the quality of the results. Toward this objective moves the investigation of the present section.

To solve the first problem of accurate and expert identification of vectors, I created photographically realistic computer-generated three-dimensional (3D) models of the vectors, which could be viewed via a head-mounted display connected to a wearable computer. The models were interactive and so could be manipulated by the viewer via a mouse or toggle input device. The manipulation included rotation in all three axes as well as zooming to any magnification supported by the resolution of the model s surface. The model itself was embedded in an internet-ready HTML web page which could be accessed offline from the computer s hard drive, a flash...
