“…We would also like to investigate the same effect in interactive scenarios with and without user tasks. Such results also entail the possibility of building decision-theoretic systems [10] based on crossmodal effects that ensure a constant perceived frame rate rather than the commonly used fixed frame rate [12].…”

The entertainment industry, primarily the video games industry, continues to dictate the development and performance requirements of graphics hardware and computer graphics algorithms. However, despite the enormous progress in the last few years it is still not possible to achieve some of industry's demands, in particular high-fidelity rendering of complex scenes in real-time, on a single desktop machine. A realisation that sound/music and other senses are important to entertainment, led to an investigation of alternative methods, such as cross-modal interaction in order to try and achieve the goal of "realism in real-time". In this paper we investigate the cross-modal interaction between vision and audition for reducing the amount of computation required to compute visuals by introducing movement related sound effects. Additionally, we look at the effect of camera movement speed on temporal visual perception. Our results indicate that slow animations are perceived as smoother than fast animations. Furthermore, introducing the sound effect of footsteps to walking animations further increased the animation smoothness perception. This has the consequence that for certain conditions the number of frames that need to be rendered each second can be reduced, saving valuable computation time, without the viewer being aware of this reduction. The results presented are another step towards the full understanding of the auditory-visual cross-modal interaction and its importance for helping achieve "realism int real-time".

“…Adaptive systems use heuristics to determine which objects, or parts of objects, to refine at runtime. The system described in (Funkhouser and Séquin, 1993) was the first such system, which used factors such as the distance of an object from the viewer and its velocity to choose from a number of fixed LOD models to render.…”

In this chapter, we will discuss the usefulness of eye-tracking for computer applications that attempt to render simulations at interactive rates. Some recent research that uses this technology is presented. While eyetracking has been relatively well-explored for the purposes of accelerating real-time rendering, it has not been very much considered with respect to the actual simulation process. In fact, perceptual issues relating to physically-based simulation have been largely neglected in the field of computer graphics. To evaluate simulations, we explore the relationship between eye-movements and dynamic events, such as collisions. We will describe some gaze-contingent systems that we and others have developed that exploit eye-tracking to enhance the perceived realism of images and simulations. Some experiments that were carried out to evaluate the feasibility of this approach are also presented.

“…The discrete multiresolution hierarchies involve computing a fixed number (usually under ½¼) levels of detail for an object. Perceptually important objects in a visual scene are then rendered using higher levels of detail and perceptually unimportant objects are rendered using lower levels of detail [16]. Such schemes are useful for applications where the perceptual importance varies significantly from one object to another, but not across the same object.…”

Triangle strips are a widely used hardware-supported data-structure to compactly represent and efficiently render polygonal meshes. In this paper we survey the efficient generation of triangle strips as well as their variants. We present efficient algorithms for partitioning polygonal meshes into triangle strips. Triangle strips have traditionally used a buffer size of two vertices. In this paper we also study the impact of larger buffer sizes and various queuing disciplines on the effectiveness of triangle strips. View-dependent simplification has emerged as a powerful tool for graphics acceleration in visualization of complex environments. However, in a view-dependent framework the triangle mesh connectivity changes at every frame making it difficult to use triangle strips. In this paper we present a novel data-structure, Skip Strip, that efficiently maintains triangle strips during such view-dependent changes. A Skip Strip stores the vertex hierarchy nodes in a skip-list-like manner with path compression. We anticipate that Skip Strips will provide a road-map to combine rendering acceleration techniques for static datasets, typical of retained-mode graphics applications, with those for dynamic datasets found in immediate-mode applications.
