Although the optical microscope has been the main tool for observations of etched tracks in solid state nuclear track detectors for many years, there has been relatively little investigation about the optical characteristics of these tracks. This chapter describes the application of the ray tracing method to light propagation through these etched tracks. The method is shown to be able to reprod...

We propose a new technique for in-core and out-of-core GPU ray tracing using a generalization of hierarchical occlusion culling in the style of the CHC++ method. Our method exploits the rasterization pipeline and hardware occlusion queries in order to create coherent batches of work for localized shader-based ray tracing kernels. By combining hierarchies in both ray space and object space, the ...

We describe a hybrid acceleration structure for ray tracing. The is Bounding Volume Hierarchy (BVH) where the leaf nodes are tetrahedralized decent ray-surface intersection performance. use (BTH) in two-level rendering animated scenes. There BVH at top level this and proposed bottom level. test (BVH-BTH) various scenes obtained promising results against other structures terms of times. BVH-BTH ...

With the continuous improvement in ray tracing and radiosity algorithms, image synthe-sis quality has reached the level of photo realism. However, efforts to achieve real-timeperformances by implementing ray tracing and radiosity algorithms on parallelprocessors and dedicated hardware have not been very successful so far. Increasing thenumber of processors introduces a corre...

With the continuous improvement in ray tracing and radiosity algorithms, image synthesis quality has reached the level of photo realism. However, efforts to achieve real-time performances by implementing ray tracing and radiosity algorithms on parallel processors and dedicated hardware have not been very successful so far. Increasing the number of processors introduces a corresponding growth in...

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...

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...
