Practical animation of liquids

Abstract: We present a general method for modeling and animating liquids. The system is specifically designed for computer animation and handles viscous liquids as they move in a 3D environment and interact with graphics primitives such as parametric curves and moving polygons. We combine an appropriately modified semi-Lagrangian method with a new approach to calculating fluid flow around objects. This allows us to efficiently solve the equations of motion for a liquid while retaining enough detail to obtain realistic looking behavior. The object interaction mechanism is extended to provide control over the liquid s 3D motion. A high quality surface is obtained from the resulting velocity field using a novel adaptive technique for evolving an implicit surface.

Deep convolutional inverse graphics network

Abstract: This paper presents the Deep Convolution Inverse Graphics Network (DC-IGN), a model that aims to learn an interpretable representation of images, disentangled with respect to three-dimensional scene structure and viewing transformations such as depth rotations and lighting variations. The DC-IGN model is composed of multiple layers of convolution and de-convolution operators and is trained using the Stochastic Gradient Variational Bayes (SGVB) algorithm [10]. We propose a training procedure to encourage neurons in the graphics code layer to represent a specific transformation (e.g. pose or light). Given a single input image, our model can generate new images of the same object with variations in pose and lighting. We present qualitative and quantitative tests of the model's efficacy at learning a 3D rendering engine for varied object classes including faces and chairs.

Information visualization using 3D interactive animation

Abstract: UI innovations are often driven by a combination of technology advances and application demands. On the technology side, advances in interactive computer graphics hardware, coupled with low-cost mass storage, have created new possibilities for information retrieval systems in which UIs could play a more central role. On the application side, increasing masses of information confronting a business or an individual have created a demand for information management applications. In the 1980s, text-editing forced the shaping of the desktop metaphor and the now standard GUI paradigm. In the 1990s, it is likely that information access will be a primary force in shaping the successor to the desktop metapho. This article presents an experimental system, the Information Visualizer (see figure 1), which explores a UI paradigm that goes beyond the desktop metaphor to exploit the emerging generation of graphical personal computers and to support the emerging application demand to retrieve, store, manipulate, and understand large amounts of infromation. The basic problem is how to utilize advancing graphics technology to lower the cost of finding information and accessing it once found (the information's "cost structure"). We take four broad strategies: making the user's immediate workspace larger, enabling user interaction with multiple agents, increasing the real-time interaction rate between user and system, and using visual abstraction to shift information to the perceptual system to speed information assimilation and retrieval.

Introduction to Implicit Surfaces

Abstract: From the Publisher: Implicit surfaces offer special effects animators, graphic designers, CAD engineers, graphics students, and hobbyists a new range of capabilities for the modeling of complex geometric objects. In contrast to traditional parametric surfaces, implicit surfaces can easily describe smooth, intricate, and articulatable shapes. These powerful yet easily understood surfaces are finding use in a growing number of graphics applications. This comprehensive introduction develops the fundamental concepts and techniques of implicit surface modeling, rendering, and animating in terms accessible to anyone with a basic background in computer graphics. provides a thorough overview of implicit surfaces with a focus on their applications in graphics explains the best methods for designing, representing, and visualizing implicit surfaces surveys the latest research With contributions from seven graphics authorities, this innovative guide establishes implicit surfaces as a powerful and practical tool for animation and rendering.
