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.

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.

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.

Real-Time Ray Tracing
Jadavan, Rostislav ; Španěl, Michal (referee) ; Herout, Adam (advisor)
This work deals with image rendering using raytracing in realtime. After short introduction to raytracing, different technics to compute raytracing in realtime is described. Most of them can be aplied to current computers. Last part shows implementation and test results.

Photon Mapping
Nečas, Ondřej ; Španěl, Michal (referee) ; Herout, Adam (advisor)
This thesis deals with practical implementation of photon mapping algorithm. To achieve better results some basic and some more advanced methods of global illumination has been examined. These time demanding algorithms are often practically unusable and their further optimization is necessary. Optimized ray tracer is essential for practical implementation. Computing diffuse interreflection by Monte Carlo sampling is also very time demanding operation. Therefore it is appropriate to use it along with proper interpolation.

Shaders for the Mental Ray Renderin System
Dohnal, Jan ; Zuzaňák, Jiří (referee) ; Herout, Adam (advisor)
Goal of this diploma thesis is to get knowledge about history and evolution of computer graphic in area of realistic image synthesis, get knowledge about rendering system mental ray and about writing shader for it and write several shader. Create manual about writing shaders for mental ray. Get knowledge about program Maya and create a tutorial hot to get the shader into it.

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.
