Depth contours are a well-known technique for visualizing the distribution of multidimensional point data sets. We present an image-space algorithm for drawing the depth contours of a set of planar points. The algorithm is an improvement on existing algorithms based on the duality principle, implemented using 3D graphics rendering techniques.

Our university has developed a completed Multimedia CAI system of Engineering Drawing. It is available to all students of Engineering Specialties. This education software has been developed by the Department of Engineering and Computer Graphics led by Prof. Zongyi ZUO. During the process of developing the system especially the software, students played a great part in it. This paper introduces ...

This paper presents a novel educational software package which develops an Interactive Didactic Application (IDA) generated in the Polytechnic University of Catalonia (UPC), and which contains the essentials of Engineering Graphics according to ISO norms. It is an interactive multimedia application which adapts easily to all engineering studies, according to the needs of each course, and which ...
