We are studying non-photo realistic rendering (NPR) with the goal of developing an image expression tool to create artworks by the NPR technique. The purpose of most NPR researches is to simulate typical painting styles, so they focus on techniques to create brushstrokes. These superficially modified images cannot deviate far from the source photo. If a rendered image is seen from a distance, it is difficult to tell the difference from the source photo. This fact makes us realize that other important elements to add artistic expression to the photographs exist. We supposed that the distribution of bright and dark parts over the painting is essential and proposed the effective way to modify that. Our novel technique is based on knowledge about human optical illusions and basic visual design rules. We integrate this technique into our NPR system, which was used to make the artworks selected by SIGGRAPH 2002 2D art gallery. Furthermore, we present new features that allow artist to select appropriate area for extreme expressions, to create many types of brushstrokes, and to choose more than two types of brushstrokes for a single artwork.

Multimedia technology has reform the current education system and is successfully implemented for its advantages and capabilities. This paper is about the multimedia implementation in developing learning courseware to introduce basic Mathematics knowledge for preschool children within the age of 4 to 6 years old. The objectives are to design an ID Model for Mathematics Preschool and to develop multimedia courseware used as CAI and CAL tools. The constructivism theory incorporated in the form of thematic and contextual approach used to allow learners construct their own knowledge and relate it with their daily life. The courseware prototype discussed consists of three main modules including Knowing Numbers Module, Writing Numbers Module and Activities Module. The combination of multimedia elements such as graphic and animation facilitate learners to experience mathematics. The courseware is expected to act as a catalyst for the implementation of Information and Communication Technology in preschool education in Malaysia.
