3D Visualization of Urban Data Based on CityGML with WebGL

Due to the advances in computer graphics and improved network speed it is now possible to navigate in 3D virtual world in real time. Until now, technologies employed require to install standalone application or plugins on navigators. The arrival of HTML 5 brings news solutions to visualize 3D data in a browser with WebGL. Several globe projects have proven that such technologies can be employed...

Geometric and Statistical Methods for Processing 3D Anthropometric Data

3D anthropometric data obtained from 3D imaging technology provide unprecedented information about the human shape. At the same time, 3D data present tremendous new challenges. New software tools and analytical methods have to be designed to realize the full potential of the 3D data. One prominent character of the 3D data is that they are a collection of coordinates in 3-space and do not have a...

metrics for the detection of changed buildings in 3d old vector maps using als data (case study: isfahan city)

هدف از این تحقیق، ارزیابی و بهبود متریک های موجود جهت تایید صحت نقشه های قدیمی سه بعدی برداری با استفاده از ابر نقطه حاصل از لیزر اسکن جدید شهر اصفهان می باشد . بنابراین ابر نقطه حاصل از لیزر اسکنر با چگالی حدودا سه نقطه در هر متر مربع جهت شناسایی عوارض تغییر کرده در نقشه های قدیمی سه بعدی استفاده شده است. تمرکز ما در این تحقیق بر روی ساختمان به عنوان یکی از اصلی ترین عارضه های شهری می باشد. من...

Validation Process for CFD Simulations of Wind Around Buildings

Our study is based on a great number of CFD (computational fluid dynamics) simulations to evaluate wind comfort at the pedestrian level. This article explains the method used to validate our CFD simulations carried out with the FLUENT software. This validation is based on a comparison between our simulated results and wind tunnel tests for three different building contexts: a single building, t...
