Rendering Chess Using Ray Tracing
Vaverka, Martin ; Jošth, Radovan (referee) ; Herout, Adam (advisor)
This work aims at rendering 3D scene using ray tracing. It describes advantages and disadvantages of this technology and its alternation known as distributed ray tracing. Other part deals with method from different branch, which are closely related to distributed ray tracing - constructive solid geometry and procedural texturing.

Frameless Rendering
Najman, Pavel ; Pečiva, Jan (referee) ; Havel, Jiří (advisor)
The aim of this work is to create a simple raytracer with IPP library, which will use the frameless rendering technique. The first part of this work focuses on the raytracing method. The next part analyzes the frameless rendering technique and its adaptive version with focus on adaptive sampling. Third part describes the IPP library and implementation of a simple raytracer using this library. The last part evaluates the speed and rendering quality of the implemented system.

"Fisheye" Camera Projection
Macík, Pavel ; Juránek, Roman (referee) ; Seeman, Michal (advisor)
The thesis describes theoretical fundamentals of optics and problems of ray-tracing method, ray-triangle intersection computation included. Next section describes concept of three different camera models for ray-tracing method - plain camera, pinehole camea and spherical camera (fish-eye). The thesis comparse properties and capabilities of camera models and their effect to projected image of a scene. The program for raytracing was implemented for purposes of the thesis including implementation of camera models described in the thesis.

Real-Time Ray Tracing
Blecha, Vít ; Sumec, Stanislav (referee) ; Herout, Adam (advisor)
My thesis deal with method of rendering computer graphics called ray tracing. I will aim on possibility of rendering triangles using this method. Goal of my work is study of existing algorithms to test ray-triangle intersection, their comparison, their computing demandingness and speed on different pc architectures. I will also implement these algorithms to existing ray tracer working in real-time.

Ray Tracing Using k-D Tree
Musil, Petr ; Jošth, Radovan (referee) ; Havel, Jiří (advisor)
This thesis describes the design and implementation of an application for picture synthesis using ray tracing. The goal is to verify properties of an space subdivision optimalization method using KD tree. The work compares spatial median, objects median and cost model methods for splitting plane determination during KD-tree construction. Several test scenes are used for evaluation.

Fast Computation of Ray-Triangle Intersection
Procházka, Václav ; Havel, Jiří (referee) ; Herout, Adam (advisor)
In this thesis we try to examine speed of 6 methods for ray-triangle intersection computation, which is elementary operation performed in raytracing. We examine their software implementations in C++ and SSE, for both single-ray and 4-ray packet implementation, as well as their hypothetical hardware implementation. Methods are tested with both randomly generated and real scenes and best results were measured for method Havel Herout (SSE4) among single-ray implementations and Shevtsov's method (SSE) among ray-packet implementations, where Shevtsov's method is of those two more suitable for hardware implementation.

Optimized Ray Tracing
Brich, Radek ; Herout, Adam (referee) ; Zemčík, Pavel (advisor)
Goal of this work is to write an optimized program for visualization of 3D scenes using ray tracing method. First, the theory of ray tracing together with particular techniques are presented. Next part focuses on different approaches to accelerate the algorithm. These are space partitioning structures, fast ray-triangle intersection technique and possibilities to parallelize the whole ray tracing method. A standalone chapter addresses the design and implementation of the ray tracing program.

Parallelization of Ray Tracing
Čižek, Martin ; Juránek, Roman (referee) ; Herout, Adam (advisor)
Ray tracing is widely used technique for realistic rendering of computer scenes. Its major drawback is time needed to compute the image, therefore it's usually parallelized. This thesis describes parallelization and ray tracing in general. It explains the possibility of how can be ray tracing parallelized as well as it defines the problems which may occur during the process. The result is parallel rendering application which uses selected ray tracing software and measurement of how successful this application is.

Pathtracing on GPU
Březina, Karel ; Kobrtek, Jozef (referee) ; Polok, Lukáš (advisor)
This bachelor thesis focuses on the acceleration of rendering algorithm pathtracing. Thesis's goal is demonstration and performance comparison between implementation on CPU and GPU. Both implementations will be discussed and compared between themselves. Furthermore, will be describe possibilities of extending existing application.
