TL;DR: This approach unifies existing computer graphics techniques for simulating fluids and extends them by incorporating more complex behavior based on the Navier–Stokes equations which couple momentum and mass conservation to completely describe fluid motion.
Abstract: We present a comprehensive methodology for realistically animating liquid phenomena Our approach unifies existing computer graphics techniques for simulating fluids and extends them by incorporating more complex behavior It is based on the Navier–Stokes equations which couple momentum and mass conservation to completely describe fluid motion Our starting point is an environment containing an arbitrary distribution of fluid, and submerged or semisubmerged obstacles Velocity and pressure are defined everywhere within this environment and updated using a set of finite difference expressions The resulting vector and scalar fields are used to drive a height field equation representing the liquid surface The nature of the coupling between obstacles in the environment and free variables allows for the simulation of a wide range of effects that were not possible with previous computer graphics fluid models Wave effects such as reflection, refraction, and diffraction, as well as rotational effects such as eddies, vorticity, and splashing are a natural consequence of solving the system In addition, the Lagrange equations of motion are used to place buoyant dynamic objects into a scene and track the position of spray and foam during the animation process Typical disadvantages to dynamic simulations such as poor scalability and lack of control are addressed by assuming that stationary obstacles align with grid cells during the finite difference discretization, and by appending terms to the Navier–Stokes equations to include forcing functions Free surfaces in our system are represented as either a collection of massless particles in 2D, or a height field which is suitable for many of the water rendering algorithms presented by researchers in recent years

TL;DR: The fundamentals of texture mapping are surveyed, which can be spilt into two topics: the geometric mapping that warps a texture onto a surface, and the filtering necessary to avoid aliasing.
Abstract: Texture mapping is one of the most successful new techniques in high-quality image synthesis. It can enchance the visual richness of raster-scan images immensely while entailing only a relatively smann increase in computation. The technique has been applied to a number of surface attributes: surface color, surface normal, specularity, transparency, illumination, and surface displacement?to name a few. Although the list is potentially endless, the techniques of texture mapping are essentially the same in all cases. This article surveys the fundamentals of texture mapping, which can be spilt into two topics: the geometric mapping that warps a texture onto a surface, and the filtering necessary to avoid aliasing. An extensive bibliography is included.

30 Apr 1998TL;DR: In this paper, a method for compressing a mesh having a plurality of vertices, each vertex characterized by a degree equal to the number of edges incident thereon, was proposed.
Abstract: A method for compressing a mesh having a plurality of vertices, each vertex characterized by a degree equal to the number of edges incident thereon, including arranging substantially all of the vertices in a consecutive order, generating a topology list including the degrees of the vertices in the consecutive order, and providing a coded stream of signals including the topology list

1 Jan 2000TL;DR: Using affordances as a basis, it elucidate the role of the designer and the distinction between usefulness and usability and expands Gibson’s definition into a framework for design.
Abstract: The concept of affordance is popular in the HCI community but not well understood. Donald Norman appropriated the concept of affordances from James J. Gibson for the design of common objects and both implicitly and explicitly adjusted the meaning given by Gibson. There was, however, ambiguity in Norman’s original definition and use of affordances which he has subsequently made efforts to clarify. His definition germinated quickly and through a review of the HCI literature we show that this ambiguity has lead to widely varying uses of the concept. Norman has recently acknowledged the ambiguity, however, important clarifications remain. Using affordances as a basis, we elucidate the role of the designer and the distinction between usefulness and usability. We expand Gibson’s definition into a framework for design.

31 May 2010TL;DR: The findings indicate that participants preferred gestures authored by larger groups of people, such as those created by end-user elicitation methodologies or those proposed by more than one researcher.
Abstract: We compare two gesture sets for interactive surfaces---a set of gestures created by an end-user elicitation method and a set of gestures authored by three HCI researchers. Twenty-two participants who were blind to the gestures' authorship evaluated 81 gestures presented and performed on a Microsoft Surface. Our findings indicate that participants preferred gestures authored by larger groups of people, such as those created by end-user elicitation methodologies or those proposed by more than one researcher. This preference pattern seems to arise in part because the HCI researchers proposed more physically and conceptually complex gestures than end-users. We discuss our findings in detail, including the implications for surface gesture design.
