چکیده

We present a real-time urban simulation on a Personal Digital Assistant (PDA). An existing desktop urban simulation is used to automatically generate potential visibility data, sub-divide the world into areas of similar potential visibility, and generate imposter images for complex and distant objects; all of which are used to achieve interactive frame-rates on a handheld device.

Interactive Rendering of Indoor and Urban Environments on Handheld Devices by Combining Visibility Algorithms with Spatial Data Structures

This work presents a comparative study of various combinations of visibility algorithms (view-frustum culling, backface culling, and a simple yet fast algorithm called conservative backface culling) and different settings of standard spatial data structures (non-uniform Grids, BSP-Trees, Octrees, and PortalOctrees) for enabling efficient graphics rendering of both indoor and urban 3D environmen...

Optimization of Fan Geometry for Urban Train Traction Motors using Coupled Numerical Electromagnetic and Thermal Analysis

One of the most important parameters in designing electrical motors is heat generation by the motor and the way it is dissipated. Temperature rising reduce efficiency and reliability of traction motors and leads to failure. In this paper, an urban train traction motor in a 3D computational fluid dynamics (CFD) simulation has been investigated. Maxwell software for electromagnetic simulation and...
