We describe a variety of physically-based simulation techniques used to generate the motion of objects for computer animated scenes. Using cla,>sical mechanics , we model rigid , fl exible and breakable objects and their interaction with wind fields . Complex motion can be controlled by specifying initial conditions, designing wind fields , and using an interactive previewing capability to view...

Effectiveness of teaching and learning in any subject at any institution is dependent on the instructional strategies used by the teachers. This is a major factor responsible for the level of performance in any subject by the students. Learning difficulties can be solved up to a great extent by using suitable teaching methods with proper utilization of available computer techniques and tools. D...

This work is devoted to analyzing the syntax contents of an animation. In the paper we present the ANIMATION system – a system for animation scene and contents creation, retrieval and display. The object recognition mechanism in the ANIMATION system includes three steps: (1) Low level animation images analysis element recognition based on the Attribute Relational Graphs (ARG); (2) Object recogn...

This quasi-experimental study examined the effects of input-based, meaning-based output (MO) and traditional instruction (TI) on EFL learners’ grammar learning. To this end, 120 junior high school students were selected from 4 intact classes. Each class was assigned to an instructional condition, that is, textual enhancement (TE), input flood (IF), MO, and TI. Before the treatment, a multiple-c...

We describe ESPLANADE (Expert System for PLANning Animation, Design, and Editing), a knowledge-based animation presentation planner. ESPLANADE receives as input a script generated by a separate action planner and a set of communicative goals that specify what the animation is to communicate to the viewer. The presentation plan that ESPLANADE creates is a complete description of every frame of a...

Systematic phonics instruction in first language education has recently received considerable research attention due to its critical role in facilitating phonological awareness and processing skills. However, little is known about the effects of systematic phonics instruction on foreign language reading and spelling in an EFL context. This study examined the effects of spelling-based phonics in...
