Abstract:
Volume rendering is quite an old concept of representing images, dating back to the 1980's. It is very useful in the medical field for visualizing the results of a computer tomography (CT) and magnet resonance tomography (MRT) in 3D. Apart from these two major applications for volume rendering, there aren’t many other fields of usage accept from tech demos. Volumetric data does not have any limitations to the shape of an object that ordinary meshes can have. A popular way of representing volume data is through an algorithm that is called volume raycasting. There is a big disadvantage with

The digitalization leads to that many physical solutions are replaced by digital once. Especially in the surveillance and security business have humans been replaced by cameras which are monitored from a remote location. As the power of the computers has increased, live video can be analyzed to inform the controller about anomalies which a human eye could have missed. SAAB – Air Traffic Management has a digital solution to provide Air Traffic Service which is called Remote Tower.

The game industry have always looked for rendering techniques that makes the games as good looking and realistic as possible. The common approach is to use triangles built up by vertices and apply many different techniques to make it look as good as possible. When triangles are used to draw objects, there is always edges and those edges often make the objects look less realistic than desired. To reduce these visible edges the amount of triangles for an object have to be increased, but with more triangles more processing power from the graphics cards is needed.

This review presents the past and present work on GPU accelerated medical image processing, and is meant to serve as an overview and introduction to existing GPU implementations. The review covers GPU acceleration of basic image processing operations (filtering, interpolation, hist

Abstract:
The aim of this project is to design an application for mobile platform which can insert virtual objects to camera shots without disturbing the scene. The application is implemented on Windows 8.1 and Windows Phone 8.1 platforms. The scene rendering is done in DirectX with C++ programming language and the user interface is created in XAML. This text describes the relevant fundamentals of augmented reality and the selected platform and it describes advanced programming techniques such as asynchronous resources loading or advanced post processing rendering techniques.

Abstract:
The main goal of this project was to familiarize readers with the techniques used in real-time animation of 3D characters. This work is focused on two types of animation: keyframe animation and skeletal animation. There are described algorithms for software and hardware accelerated model deformations, keyframe interpolations, animation blending, inverse kinematics and ragdoll. The result of this project is a framework, which consists of an animation library, examples demonstrating library functions and tools for export animations from 3D Studio Max and MilkShape 3D.

Abstract:
Traditional methods of input on mobile devices are cumbersome and difficult to use. Devices have become smaller, while their operating systems have become more complex, to the extent that they are approaching the level of functionality found on desktop computer operating systems. The buttons and toggle-sticks currently employed by mobile devices are a relatively poor replacement for the keyboard and mouse style user interfaces used on their desktop computer counterparts. For example, when looking at a screen image on a device, we should be able to move the device to the left to indicate we

Abstract:
The aim of this work was to create a program to visualize voxel scenes in real time using ray tracing. It included the study of various methods of such a rendering with a focus on shadows. The solution was created using Unity engine and experimental packages Unity Jobs and Burst. The thesis presents multiple ray tracing passes and SVGF technique, that is used to turn a noisy input into full edge-preserving image. The final program is able to render hard shadows, soft shadows, and ambient occlusion at speed of fifty frames per second.

This thesis deals with library for recording video in the background of 3D application. A library is designed to work under the Microsoft Windows and Linux operation systems.  It records image and also sound. Image recording is supported in OpenGL, Direct3D9, Direct3D10 and Direct3D11. To reduce video data size, library supports image compression using MJPG codec. Audio is recorded by WaveForm audio, Windows Core Audio or ALSA. Recorded sound is for whole operation system. A library is able to record up to two audio streams to accommodate possible microphone input. It can mix audio data togeth

With the rapidly growing computational power of modern computers, physically based rendering has found its way into real world applications. Real-time simulations and renderings of fire and smoke had become one major research interest in modern video game industry, and will continue being one important research direction in computer graphics. To visually recreate realistic dynamic fire and smoke is a complicated problem. Furthermore, to solve the problem requires knowledge from various areas, ranged from computer graphics and image processing to computational physics and chemistry. Even though

Background The API DirectX 12 allows programmers to have more control over the GPUs memory management. This includes the ability to allocate resources on different types of memory heaps. But there is a lack of research on how these heap types affect the copying performance. Objectives The aim of this thesis is to benchmark the copying performance of the different heap types in DirectX 12 when increasing the data size. The heaps are tested with the three types of command queue that can be used to execute commands to the GPU. Method To answer our research question, a DirectX 12 prototype was imp

In the former, we use the edge-alignment algorithm to improve the image quality for SVC which is an extension from video coding standard H264/AVC. In the latter, we design the playback mechanism based on DirectShow system to achieve the goal of adaptively decode video provided by the server through the network. Basically, SVC can be divided into two parts: one base layer and several enhanceme

Abstract:
This report describes the architecture and implementation of a memory profiler for 3D graphics applications. The memory profiling is done for parts of the program which runs on the graphics processor and is responsible for rendering the image. The shaders are parsed and every memory instruction is instrumented with additional instruction for profiling. The results are then transferred from the video memory to CPU memory. Profiling is done for a frame and completes in less than three minutes. The report also describes various analyses that can be done using the results obtained from this profil
