WGL_EXT_pixel_format is required. Overview This extension provides a mechanism to antialias all GL primitives: points, lines, polygons, bitmaps, and images. The technique is to sample all primitives multiple times at each pixel. The color sample values are resolved to a single, displayable color each time a pixel is updated, so the antialiasing appears to be automatic at the application level.

    UNIVERSITY OF CALIFORNIA Los Angeles Energy-Efficient VLSI Architectures for Next- Generation Software-Defined and Cognitive Radios A dissertation submitted in partial satisfaction of the requirements for the degree Doctor of Philosophy in Electrical Engineering by Fang-Li Yuan 2014 c Copyright by Fang-Li Yuan 2014 ABSTRACT OF THE DISSERTATION Energy-Efficient VLSI Architectures for Next- Generation Software-Defined and Cognitive Radios by Fang-Li Yuan Doctor of Philosophy in Electrical Engineering University of California, Los Angeles, 2014 Professor Dejan Markovic,´ Chair Dedicated radio hardware is no longer promising as it was in the past. Today, the support of diverse standards dictates more flexible solutions. Software-defined radio (SDR) provides the flexibility by replacing dedicated blocks (i.e. ASICs) with more general processors to adapt to various functions, standards and even allow mutable de- sign changes. However, such replacement generally incurs significant efficiency loss in circuits, hindering its feasibility for energy-constrained devices. The capability of dy- namic and blind spectrum analysis, as featured in the cognitive radio (CR) technology, makes chip implementation even more challenging. This work discusses several design techniques to achieve near-ASIC energy effi- ciency while providing the flexibility required by software-defined and cognitive radios. The algorithm-architecture co-design is used to determine domain-specific dataflow ii structures to achieve the right balance between energy efficiency and flexibility. The flexible instruction-set-architecture (ISA), the multi-scale interconnects, and the multi- core dynamic scheduling are also proposed to reduce the energy overhead. We demon- strate these concepts on two real-time blind classification chips for CR spectrum anal- ysis, as well as a 16-core processor for baseband SDR signal processing.

Typeset in LATEX Gothenburg, Sweden 2016 iii Generating Real Time Reflections by Ray Tracing Approximated Geometry Johan Fredriksson, Adam Scott Department of Interaction Design and Technologies Chalmers University of Technology Abstract Rendering reflections in real time is important for realistic modern games. A com- mon way to provide reflections is by using environment mapping. This method is not an accurate way to calculate reflections and it consumes a lot of memory space. We propose a method of ray tracing approximate geometry in real time. By using approximate geometry it can be kept simple and the size of the bounding volume hierarchy will have a lower memory impact. The ray tracing is performed on the GPU and the bounding volumes are pre built on the CPU using surface area heuris- tics.

MILOSLAV ČÍŽ AUTOR PRÁCE SUPERVISOR Ing. TOMÁŠ MILET VEDOUCÍ PRÁCE BRNO 2017 Abstract This work deals with the problem of accurately rendering mirror reflections on curved surfaces in real-time. While planar mirrors do not pose a problem in this area, non-planar surfaces are nowadays rendered mostly using environment mapping, which is a method of approximating the reflections well enough for the human eye. However, this approach may not be suitable for applications such as CAD systems. Accurate mirror reflections can be rendered with ray tracing methods, but not in real-time and therefore without offering interactivity. This work examines existing approaches to the problem and proposes a new algorithm for computing accurate mirror reflections in real-time using accelerated searching for intersections with depth profile stored in cubemap textures. This algorithm has been implemented using OpenGL and tested on different platforms. Abstrakt Tato práce se zabývá problémem přesného zobrazování zrcadlových odrazů na zakřiveném povrchu v reálném čase. Zatímco planární zrcadla nepředstavují v tomto ohledu problém, zakřivené povrchy se v dnešní době zobrazují především metodou environment mapping, která aproximuje reálné odrazy a nabízí výsledky uspokojivé pro lidské oko. Tento přístup však nemusí být vhodný např. v oblasti CAD systémů. Přesných zrcadlových odrazů se dá dosáhnout pomocí metod sledování paprsku, avšak ne v reálném čase a tudíž bez možnosti interaktivity.

The surfaces are automatically parameterized in order to apply stippling textures without ma- jor distortions. The mapping process is guided by a decomposition of the space in cubes. Seamless scaling with a constant density of points is realized by subdividing and summarizing cubes. Our mip-map technique enables ar- bitrarily scaling with one texture. Different shading tones and scales are facilitated by adhering to the constraints of tonal art maps. With our stippling technique, it is feasible to encode all scaling and brightness levels within one self-similar texture. Our method is applied to surfaces extracted from (segmented) medical volume data. The speed of the stippling process enables stippling for several complex objects simultaneously. We consider applica- tion scenarios in intervention planning (neck and liver surgery planning). In these scenarios, object recognition (shape perception) is supported by adding stippling to semi-transparently shaded objects which are displayed as context information.

The maps are generally drawn as 2D bitmaps with height properties but when rendered gives the appearance of being 3D. 3D Refers to the ability to move in the X, Y and Z axis and also rotate around the X, Y, and Z axes. Axis-aligned Bounding Box A form of a bounding box where the box is aligned to the axis therefore only two points in space are (AABB) needed to define it. AABB’s are much faster to use, and take up less memory, but are very limited in the sense that they can only be aligned to the axis. Albedo An albedo is a physical measure of a material’s reflectivity, generally across the visible spectrum of light. An albedo texture simulates a surface albedo as opposed to explicitly defining a colour for it. Alpha Blending Assigning varying levels of translucency to graphical objects, allowing the creation of things such as glass, fog, and ghosts.

    Real-Time Recursive Specular Reflections on Planar and Curved Surfaces Using Graphics Hardware

    REAL-TIME RECURSIVE SPECULAR REFLECTIONS ON PLANAR AND CURVED SURFACES USING GRAPHICS HARDWARE Kasper Høy Nielsen Niels Jørgen Christensen Informatics and Mathematical Modelling The Technical University of Denmark DK 2800 Lyngby, Denmark {khn,njc}@imm.dtu.dk ABSTRACT Real-time rendering of recursive reflections have previously been done using different techniques. How- ever, a fast unified approach for capturing recursive reflections on both planar and curved surfaces, as well as glossy reflections and interreflections between such primitives, have not been described. This paper describes a framework for efficient simulation of recursive specular reflections in scenes containing both planar and curved surfaces. We describe and compare two methods that utilize texture mapping and en- vironment mapping, while having reasonable memory requirements. The methods are texture-based to allow for the simulation of glossy reflections using image-filtering. We show that the methods can render recursive reflections in static and dynamic scenes in real-time on current consumer graphics hardware. The methods make it possible to obtain a realism close to ray traced images at interactive frame rates. Keywords: Real-time rendering, recursive specular reflections, texture, environment mapping. 1 INTRODUCTION mapped surface sees the exact same surroundings re- gardless of its position.
