Capstone Projects:OpenGL and C++ Usage Study

Advantages of OpenGL and C++

OpenGL can be hardware accelerated Designed for High Performance 2D and 3

applications OpenGL and C++ are compiled, increases

application speed efficiency Has been successfully used by other companies

and similar products Some code is already available to us

Disadvantages of OpenGL and C++ Much Harder to debug in comparison to Java

(specifically memory management) OpenGL is only for 2D and 3D visuals, there are

no GUI components to it Requires another package to provide UI controls Difficult to deliver content to a browser, if needed

Possible Solutions

GLUT: OpenGL Utility Toolkit Eases development of OpenGL Applications Window System Independent Open Source / C++ API

Qt: Cross Platform Application Framework Complete GUI Toolkit Eases development of OpenGL Applications Open Source / C++ API Commercial Licenses available

3D Models

Avatars

These are 3D models of vehicles available for purchase at 3dcadbrowser.com

Available in various CAD and 3D software formats

Is the cost justified? Simpler objects can be used for development

Maps and Vector Data Resources

“LION” File

In New York City, the best digital representation of the city’s street network is the “LION” file created by the NYC Department of City Planning. The LION file portrays each and every street segment in the five boroughs, with detailed address ranges on the left and right side of each segment. The LION file includes: Local streets Parkways and expressways Paths Streets that have been mapped only
