A small set of geometric primitives: Points Lines Geometric primitives Polygons Images Image primitives Bitmaps OpenGL Libraries OpenGL core library OpenGL32 on Windows GL/Mesa on most unix/linux systems OpenGL Utility Library (GLU) Provides functionality in OpenGL core but avoids having to rewrite code GL is window system independent Extra libraries are needed to connect GL to the OS GLX – X windows, Unix AGL – Apple Macintosh WGL – Microsoft Windows GLUT OpenGL Utility Toolkit (GLUT) Provides functionality common to all window systems Open a window Get input from mouse and keyboard Menus Event-driven Code is portable but GLUT is minimal Software Organization application program OpenGL Motif widget or similar GLUT GLX, AGL or WGL GLU X, Win32, Mac O/S GL software and/or hardware OpenGL Architecture Immediate Mode Geometric pipeline Per Vertex Polynomial Operations & Evaluator Primitive Assembly Display Per Fragment Frame Rasterization CPU List Operations Buffer Texture Memory Pixel Operations OpenGL State OpenGL is a state machine OpenGL functions are of two types Primitive generating Can cause output if primitive is visible How vertices are processed and appearance of primitive are controlled by the state State changing Transformation functions Attribute functions Typical GL Program Structure Configure and open a window Initialize GL state Register callback functions Render Resize Events Enter infinite event processing loop Render/Display Draw simple geometric primitives Change states (how GL draws these primitives) How they are lit or colored How they are mapped from the user's two- or three-dimensional model space to the two- dimensional screen. -
History and Evolution of the Android OS
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Springer - Publisher Connector CHAPTER 1 History and Evolution of the Android OS I’m going to destroy Android, because it’s a stolen product. I’m willing to go thermonuclear war on this. —Steve Jobs, Apple Inc. Android, Inc. started with a clear mission by its creators. According to Andy Rubin, one of Android’s founders, Android Inc. was to develop “smarter mobile devices that are more aware of its owner’s location and preferences.” Rubin further stated, “If people are smart, that information starts getting aggregated into consumer products.” The year was 2003 and the location was Palo Alto, California. This was the year Android was born. While Android, Inc. started operations secretly, today the entire world knows about Android. It is no secret that Android is an operating system (OS) for modern day smartphones, tablets, and soon-to-be laptops, but what exactly does that mean? What did Android used to look like? How has it gotten where it is today? All of these questions and more will be answered in this brief chapter. Origins Android first appeared on the technology radar in 2005 when Google, the multibillion- dollar technology company, purchased Android, Inc. At the time, not much was known about Android and what Google intended on doing with it. Information was sparse until 2007, when Google announced the world’s first truly open platform for mobile devices. The First Distribution of Android On November 5, 2007, a press release from the Open Handset Alliance set the stage for the future of the Android platform. -
Rowpro Graphics Tester Instructions
RowPro Graphics Tester Instructions What is the RowPro Graphics Tester? The RowPro Graphics Tester is a handy utility to quickly check and confirm RowPro 3D graphics and live water will run in your PC. Do I need to test my PC graphics? If any of the following are true you should test your PC graphics before installing or upgrading to RowPro 3: If your PC shipped new with Windows XP. If you are about to upgrade from RowPro version 2. If you have any doubts or concerns about your PC graphics system. How to download and install the RowPro Graphics Tester Click the link above to download the tester file RowProGraphicsTest.exe. In the download dialog box that appears, click Save or Save this program to disk, navigate to the folder where you want to save the download, and click OK to start the download. IMPORTANT NOTE: The RowPro Graphics Tester only tests if your PC has the required graphics components installed, it is not a graphics performance test. Passing the RowPro Graphics Test is not a guarantee that your PC will run RowPro at a frame rate that is fast enough to be useful. It is however an important test to confirm your PC is at least equipped with the necessary graphics components. How to run the RowPro Graphics Tester 1. Run RowProGraphicsTest.exe to run the test. The test normally completes in less than a second. 2. If any of the results show 'No', check the solutions below. 3. Click the x at the top right of the test panel to close the test. -

Introduction to the Software Libraries Opengl: Open Graphics Library GLU: Opengl Utility Library Glut: Opengl Utility Toolkit
Introduction to the software libraries This course makes use of several popular libraries to help build sophisticated portable graphics applications with minimal effort. The following diagram gives an overview of the packages and how they interact. For the purposes of this course, one can think of the GLU and glut libraries as being part of the OpenGL library or the OpenGL API (application programmer's interface), eventhough this is not really the case. -provides a software interface to graphics hardware and OpenGL implements most of the graphics functionality. provides support for some additional operations and primitive GLU types, and is implemented using OpenGL function calls designed specifically to be used with OpenGL and it takes care of things like opening windows, redraw events, and keyboard and glut mouse input. It effectively hides all the windowing system dependencies for OpenGL. OpenGL: Open Graphics Library • standardized 3D graphics library (API) • available on many platforms, often with hardware support • derivative of the Silicon Graphics' GL library • all function calls have the gl prefix, e.g.: glScale3fv() • OpenGL resources on the Internet** GLU: OpenGL Utility Library • support for NURBS surfaces, quadric surfaces, surface trimming, ... • all function calls have the glu prefix, e.g.: gluOrtho2D() • comes with all OpenGL implementations, including Windows and Mesa, no separate installation required • typically involves no hardware acceleration • glu32.dll on Win95/Win98/WinNT, look in same directory as Opengl32.dll -
Opengl API Introduction Agenda
OpenGL API Introduction Agenda • Structure of Implementation • Paths and Setup • API, Data Types & Function Name Conventions • GLUT • Buffers & Colours 2 OpenGL: An API, Not a Language • OpenGL is not a programming language; it is an application programming interface (API). • An OpenGL application is a program written in some programming language (such as C or C++) that makes calls to one or more of the OpenGL libraries. • Does not mean program uses OpenGL exclusively to do drawing: • It might combine the best features of two different graphics packages. • Or it might use OpenGL for only a few specific tasks and environment- specific graphics (such as the Windows GDI) for others. 3 Implementations • Although OpenGL is a “standard” programming library, this library has many implementations and versions. • On Microsoft Windows the implementation is in the opengl32.dll dynamic link library, located in the Windows system directory. • The OpenGL library is usually accompanied by the OpenGL utility library (GLU), which on Windows is in glu32.dll,. • GLU is a set of utility functions that perform common tasks, such as special matrix calculations, or provide support for common types of curves and surfaces. • On Mac OS X, OpenGL and the GLU libraries are both included in the OpenGL Framework. • The steps for setting up your compiler tools to use the correct OpenGL headers and to link to the correct OpenGL libraries vary from tool to tool and from platform to platform. 4 Include Paths • On all platforms, the prototypes for all OpenGL functions, types, and macros #include<windows.h> are contained (by convention) in the #include<gl/gl.h> header file gl.h. -
