Computer animation has always looked too glossy and shiny, which is why traditional cartoon specialists, such as Matt Groening have often avoided using the 3D computer graphic medium as a solution. Traditional animation's flexibility in terms of choice of appearance and style is appealing but in certain aspects it is very time consuming. There is therefore a need to develop techniques that exploit the speed of computer animation but provide the variety of styles of traditional animation. This paper attempts to simulate hand drawn cartoon animation styling while incorporating traditional exaggerated cartoon movement.

The paper asks whether active networks might offer potential solutions to scalability issues for large scale distributed virtual environments (DVE). The paper considers current directions in the architecture of DVE systems and work in active network research and suggests potentially beneficial synergies between the two fields.

Web-based learning is in its infancy and has the potential to drive immense developments in learning technologies. With advances in videoconferencing software and the move towards a broadband Britain, a new opportunity has arisen for distributed learning to take place whilst retaining synchronous contact with a tutor. De Montfort University's REal time Access to Learning IT (REALITY) is remote, real-time, computer based training in computer applications. It uses a combination of desktop videoconferencing and application sharing to provide remote, distributed, learners with live tuition. The target audience for REALITY are people who, for whatever reason, cannot readily access traditional learning establishments but for whom distance learning is not an option either. The aim is to provide training facilities at a variety of times and locations which are local and familiar and which avoid the potentially negative connotations of traditional educational institutions. With funding from BT, the initial phases of the project are now complete and have been evaluated. The findings indicate that despite technical difficulties and the strain of working at a distance using unfamiliar technology, most of the participants responded favourably to their REALITY experiences.
基于网络的学习还处于起步阶段，有潜力推动学习技术的巨大发展。随着视频会议软件的进步和宽带英国的发展，在与导师保持同步联系的同时进行分布式学习的新机会出现了。德蒙特福特大学(De Montfort University)的REal time Access to Learning IT (REALITY)是一种远程、实时、基于计算机的计算机应用培训。它结合了桌面视频会议和应用程序共享，为远程、分布式的学习者提供实时教学。REALITY的目标受众是那些无论出于何种原因，无法轻易进入传统学习机构，但对他们来说，远程学习也不是一个选择的人。其目的是在各种时间和地点提供当地和熟悉的培训设施，并避免传统教育机构的潜在负面含义。在英国电信的资助下，项目的初始阶段现已完成并已进行评估。研究结果表明，尽管存在技术上的困难和使用不熟悉的技术进行远距离工作的压力，但大多数参与者对他们的现实体验反应良好。

This paper presents a general framework for synchronising motion curves to music in computer animation. Motions are locally modified using perceptual cues extracted from the music. The key to this approach is the use of standard music analysis techniques on complementary MIDI and audio representations of the same soundtrack. These musical features then guide the motion editing process. It allows users to easily combine different aspects of the music with different aspects of the motion.

Over the past decade there has emerged a growing number of sculptors, from around the globe, who have found a use for the computer in their research and practice. For some it offers a design tool but for others it has become a new media. A new integral imaging system capable of real-time capture and replay and methods of computer generation of synthetic integral images has been developed. Keith Brown, a sculptor was intrigued at the possibilities this offers as a means through which to realize cyber-sculptures as true 3D optical constructs. This paper presents the most recent results of the collaboration between Keith Brown and the Imaging Technologies Group at De Montfort University.

The implementation of displacement mapping on subdivision surfaces is discussed in this paper The subdivision surface has recently drawn a lot of attention in the area of geometric modeling, multiresolution surface representation and geometric compression. In our research, we have developed the versatility and extensibility of this technique. The subdivision surface technique can be conveniently incorporated with many existing surface modeling methodologies. In this paper we present the amalgamation of the subdivision surface and displacement mapping, for producing realistic surface details.

It is highly desirable in terms of speed and computational costs to perform image indexing and retrieval in the compressed domain. The exponential growth of digital media on both the WWW (Reddy and Fletcher, 1998) and home imaging equipment has prompted the development of faster, more accurate indexing algorithms. Successful techniques have the ability to summarise the features of an image into a relatively small key. We present a technique that uses the features of a genetic algorithm to quantize the content of an image directly in the DCT domain. The benefits of working in this domain, apart from the substantial savings of avoiding image reconstruction, is that the coefficients provide spatial information in a form well suited for image indexing.

We present a novel perception based technique of texture interpolation for view dependent projective texture mapping of image based models. When interpolating projected texture maps, regions of texture incongruence can generate artefacts. Non congruent texture regions are the result of unmodelled features in the geometric scene model. We show how a perception based metric can be used to control the interpolation process and reduce these artefacts. The metric, based upon the human perception of Mach bands, is also used to evaluate the new interpolation method against current techniques.

We present a technique to perform real-time collision detection of two complex 3D polygon objects using commodity and workstation rendering hardware. This technique is O(n), and performs favorably in comparison to existing traditional methods in many circumstances. On PCs or workstations, this technique can be performed almost entirely in rendering hardware. This frees general CPU cycles for other processing tasks. Alternatively, more CPU cycles can be used for collision detection, freeing rendering hardware cycles for other tasks. This technique is also highly customizable to specific applications.

The contribution of this paper is a novel non-photorealistic rendering (NPR) technique, capable of producing an artificial 'hand-painted' effect on 2D images, such as photographs. Our method requires no user interaction, and makes use of image salience and gradient information to determine the implicit ordering and attributes of individual brush strokes. The benefits of our technique are complete automation, and mitigation against the loss of image detail during painting. Strokes from lower salience regions of the image do not encroach upon higher salience regions; this can occur with some existing painting methods. We describe our algorithm in detail, and illustrate its application with a gallery of images.
