We present a robust and efficient approach to directly slicing implicit solids. Different from prior slicing techniques that reconstruct contours on the slicing plane by tracing the topology of intersected line segments, which is actually not robust, we generate contours through a topology guaranteed contour extraction on binary images sampled from given solids and a subsequent contour simplification algorithm which has the topology preserved and the geometric error controlled. The resultant contours are free of self-intersection, topologically faithful to the given r-regular solids and with shape error bounded; therefore, correct objects can be fabricated from them by rapid prototyping. Moreover, since we do not need to generate the tessellated B-rep of given solids, our approach is memory efficient — only the binary image and the finest contours on one particular slicing plane need to be stored in-core. Our method is general and can be applied to any implicit representations of solids.

This chapter presents a method for foreign language (FL) teachers to implement currently available technologies as instructional tools in a FL language classroom using the memory efficient approach (MEA) to enhance instruction, and help students to become lifelong FL learners. Providing historical backgrounds of the FL acquisition or learning theory as well as technological implementation for FL instruction, the chapter suggests MEA with eclectic methodology for FL instruction. Under the MEA, the methods for “skill-using” and “skill-getting” (Rivers, 1985) are employed; thus, appropriate methods as well as appropriate instructional tools—technological and nontechnological—are selected according to the learning objective or goal. In addition, introducing emerging technologies that may be utilized for instruction in the FL area, the chapter will demonstrate a method to implement technologies in advanced Japanese courses as well as in elementary Japanese courses using MEA.
