Modern GPUs with their several hundred cores and more accessible programming models are becoming attractive devices for compute-intensive applications. They are particularly well suited for applications, such as image processing, where the end result is intended to be displayed via the graphics card. One of the more versatile and powerful graphics techniques is ray tracing. However, tracing eac...

Interactive ray tracing has seen enormous progress in recent years. However, advanced rendering techniques requiring many million rays per second are still not feasible at interactive speed, and are only possible by means of highly parallel ray tracing. When using compute clusters, good load balancing is crucial in order to fully exploit the available computational power, and to not suffer from...

We present a practical and efficient algorithm for interactively ray tracing arbitrary implicit surfaces. We use interval arithmetic both for reliable numerical computation and guaranteed detection of topological features. In conjunction with ray tracing, this allows for rendering literally any implicit surface simply from its definition. Interactive ray tracing facilitates flexible shading and...

Mobile computing in the form of smart phones and tablets is becoming ubiquitous. As these devices are being used for increasingly sophisticated tasks, the graphics requirements are also increasing. With the growing desire for highly realistic graphics, the use of ray tracing for rendering will become essential. Ray tracing efficiently models complex illumination effects to improve visual realis...

The paper presents a single-pass, view-dependent method to solve the general rendering equation, using a combined finite element and random walk approach. Applying finite element techniques, the surfaces are decomposed into planar patches on which the radiance is assumed to be combined from finite number of unknown directional radiance functions by predefined positional basis functions. The dir...

In this paper we introduce a method for acceleration of the real time ray tracing by using characteristic traits of visual perception. Ray tracing is a demanding rendering technique which is much slower than currently dominating scanline methods. Performance hit especially arise when we use huge amount of samples for anti-aliasing or other sample-based effects. We show how to decreases number o...

Distribution ray tracing uses multiple samples per pixel to produce antialiased images that include soft shadows, glossy reflection, motion blur, and depth-of-field. The two main potential barriers to making distribution ray tracing interactive are that many rays might be required, and that those rays are not coherent enough to derive efficiency from tracing them in packets. A new interleaved s...

ion de nes an object which is a procedural entity capable of a small number of elementary operations. Objects and Object Classes Within the kernel, an object is a data abstraction for geometrical entities and operations. Figure 1 shows the routines which are required to de ne a parametric family of objects, or an object class. Each of these routines accepts a pointer to class-speci c data, or p...
