Powerpoint Sunusu DIGITAL MEDIA, A GENERAL OVERVIEW Visual Communication 2 and Perspective Course | Spring Semester 18’ WHAT IS DIGITAL? Digital describes electronic technology that generates, stores, and processes data in terms of two states: positive and non-positive. Positive is expressed or represented by the number 1 and non-positive by the number 0. Thus, data transmitted or stored with digital technology is expressed as a string of 0's and 1's. Each of these state digits is referred to as a bit. WHAT IS ANALOG? Analog describes a device or system that represents changing values as continuously variable physical quantities. Analog radio, telephone or a microphone are typical examples of analog devices.

  • Efficient Rendering of Caustics with Streamed Photon Mapping
    BULLETIN OF THE POLISH ACADEMY OF SCIENCES TECHNICAL SCIENCES, Vol. 65, No. 3, 2017 DOI: 10.1515/bpasts-2017-0040 Efficient rendering of caustics with streamed photon mapping K. GUZEK and P. NAPIERALSKI* Institute of Information Technology, Lodz University of Technology, 215 Wolczanska St., 90-924 Lodz, Poland Abstract. In this paper, we present the streamed photon mapping method for enhancing the rendering of caustics. In order to achieve a realistic caustic effect, global illumination methods require additional data, which are gathered by creating a caustic map or increasing the number of samples used for rendering. Our method employs a stream of photons with a varying luminance level depending on the material properties of the surface. The application of a concentrated photon stream provides the ability to render caustics effectively without increasing the number of photons in a photon map. Such an approach increases visibility of results, while also allowing for faster computations. Key words: rendering, global illumination, photon mapping, caustics. 1. Introduction 2.

Tutkimusprojektit kasvavat jatkuvasti, mikä aiheuttaa tarpeen suuremmalle tietokoneteholle ja lisää kustannuksia. Ratkaisuksi tähän ongelmaan tiedemiehet ovat kehittäneet hajautetun laskennan järjestelmiä, joiden tarkoituksena on tarjota vaihtoehto kalliille supertietokoneille. Näiden järjestelmien toiminta perustuu yhteisön lahjoittamaan tietokonetehoon. Open Rendering Environment on Laurea-ammattikorkeakoulun aloittama projekti, jonka tärkein tuotos on yhteisöllinen renderöintipalvelu Renderfarm.fi. Palvelu hyödyntää hajautettua laskentaa nopeuttamaan 3D-animaatioiden renderöintiä. Tämä tarjoaa uusia mahdollisuuksia mallintajille ja animaatioelokuvien tekijöille joilta tavallisesti kuluu paljon aikaa ja tietokoneresursseja töidensä valmiiksi saattamiseksi.

In the theoretical part the overview of light phenomena and their simulation in virtual space is presented. This is followed by a detailed presentation of the main rendering methods and the results and limitations of their applications to 3D ob- jects. At the end of the theoretical part the importance of a proper testing scene and especially the role of Cornell box are explained. In the experimental part the terms and conditions as well as hardware and software used for the research are presented. This is followed by a description of the procedures, where we focused on the rendering quality and time, which enabled the comparison of settings of different render engines and determination of conditions for further rendering of testing scenes. The experimental part continued with rendering a variety of simple virtual scenes including Cornell box and virtual object with different materials and colours. Apart from visual evaluation, which was the starting point for comparison of renderings, a procedure for numerical estimation and colour deviations of ren- derings using the selected regions of interest in the final images is presented.

  • Mimicking POV-Ray Photorealistic Rendering with Accelerated Opengl Pipeline
    Mimicking POV-Ray Photorealistic Rendering with Accelerated OpenGL Pipeline J. Peč iva P. Zemč ík J. Navrátil Brno University of Technology Brno University of Technology Brno University of Technology Božetě chova 2 Božetě chova 2 Božetě chova 2 612 66 Brno, Czech Republic 612 66 Brno, Czech Republic 612 66 Brno, Czech Republic [email protected] [email protected] [email protected] ABSTRACT Traditional ray tracing algorithms tend to provide photorealistic results but at high computing costs. Rendering times of minutes or days are not exceptional. On the other side, hardware accelerated OpenGL rendering can provide real-time interaction with virtual environment with unnoticeable rendering times. This paper attempts to bring these two together and attempts to give an answer on the difficulty of implementing real-time photorealistic rendering. The paper presents case study on mimicking of POV-Ray photorealistic rendering with accelerated OpenGL pipeline. The study shows the opportunity to accelerate some photorealistic algorithms by real-time approaches while, on the other side, it locates the parts that are difficult to replace by traditional real-time rendering paradigms. Particularly, it is shown how to implement primary and shadow rays and POV-Ray-like material model using accelerated OpenGL pipeline using modern shader techno- logy. On the other side, the difficulties of reflected and refracted rays implementation using real-time rendering approaches is discussed. Keywords photorealistic rendering, POV-Ray, OpenGL, raytracing, shaders 1 Introduction graphics usually tend to provide poor results on advanced scene lighting setups. If real-time photorealistic visualizations would be Photorealistic rendering is a very important domain in computer possible, they would provide high quality visualizations, making graphic because of the realism that is often expected from architects and designers much more time effective while graphics applications.
