Descriptive Geometry and Engineering Graphics

The multimedia support system for lectures in Descriptive Geometry and Engineering Graphics is developed using the Flash technology in order to address the system complexity: the presence of a large number of drawings, vector models, 3D animation and interactive elements. An innovative driver is created allowing the teacher to zoom in/out any drawing on the slide using the mouse wheel and drag any scrollable content with the mouse. All graphical materials are transformed to the vector format, thus it is not distorting upon zooming. The short mouse click is used to move the slides forward, the long mouse click is used to move backward. Particular attention is given to the system performance so that it runs online very fast even with the rich and complex graphics.
