ÐIn this paper, we consider accelerated rendering of high quality walkthrough animation sequences along predefined paths. To improve rendering performance, we use a combination of a hybrid ray tracing and Image-Based Rendering (IBR) technique and a novel perception-based antialiasing technique. In our rendering solution, we derive as many pixels as possible using inexpensive IBR techniques with...

This paper tries to find the various functions involved in an animation system and how virtual reality techniques and multimedia input could play a role. A classification of VR-based methods is proposed: real-time rotoscopy methods, real-time direct metaphors and real-time recognitionbased metaphors. Several examples are presented: 3D shape creation, camera motion, body motion control, hand ani...

In this paper, we show how 3-D input devices used in virtual reality may drastically change the way of designing animation scenes. We analyze the various stages of animation production and show when and how these new concepts/devices may be involved into the creation process. We illustrate this new approach by describing the 5th Dimension animation system developed in our laboratories. We empha...

This research aims to investigate the affects and advantages of the various media so that instructions and learning can be more effective. The principle of redundancy states that students learn better from animation and narration than from animation, narration, and text. This study applied the redundancy principle and investigated how students benefited from different types of animation and mod...

This study investigated the effectiveness of various types of worked-out examples used in pre-training to optimize the cognitive load and enhance learners’ comprehension of the content in an animation-based learning environment. An animation-based learning environment was developed specifically for this study. The participants were divided into four groups; each group was provided with a differ...

Rough diagrams are useful in communication and planning, but static diagrams can be insufficient to express motion. While for many applications animation is effective in depicting movement and temporal relationships, it is difficult and often tedious to create. We explore the use of motion-recording techniques to simplify the animation process. Event timing is controlled by providing additional...
