The Ring programming language version 1.9 book - Part 63 of 210
0 likes6 views
The document discusses using RingOpenGL and RingFreeGLUT for 3D graphics development in Ring. RingOpenGL provides bindings to the OpenGL graphics library, supporting versions from OpenGL 1.1 to 4.6. RingFreeGLUT contains bindings for the FreeGLUT library. Sample code shows how to create an OpenGL window and context using FreeGLUT, and draw basic shapes like triangles and polygons using RingOpenGL functions. The document provides examples of drawing a triangle, quadrilaterals with different colors, and the basics of creating an OpenGL window.

- 3. CHAPTER SIXTY BUILDING GAMES FOR ANDROID In this chapter we will learn about Building RingLibSDL Games for Mobile. So we can create packages (*.apk) for the applications that are developed using Ring Game Engine for 2D Games. 60.1 Download Requirements and Update the Android SDK • The Android SDK Tools https://developer.android.com/studio/index.html • The Android NDK (Tested using android-ndk-r10c) https://developer.android.com/ndk/index.html • Apache Ant v1.8 or later http://ant.apache.org/bindownload.cgi • Java SE Development Kit (JDK) v6 or later http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html • Update the Android SDK to get the API and tools packages required for development Tested using Android 4.4.2 (API 19) • In Windows - Define the next Environment Variables based on your system. 1. JAVA_HOME For Example : C:Program Files (x86)Javajdk1.8.0_05 2. ANDROID_HOME For Example : B:mahmoudToolsJava-Androidadt-bundle-windows-x86-20140702sdk 60.2 Project Folder Open the project folder : ring/android/ringlibsdl/project 591
- 4. Ring Documentation, Release 1.9 You can add the source code (*.ring) and Images/Sound Files to the assets folder. You will find the Flappy Bird 3000 Game ready for building. The execution starts from the start.ring file load "game2.ring" 60.3 Building the project Move to the ring/android/ringlibsdl/project folder We can build using the next command (We need to do this for one time only). ndk-build Then we can create the package (*.apk) using the next command. 60.3.

CHAPTER SIXTYONE USING RINGOPENGL AND RINGFREEGLUT FOR 3D GRAPHICS In this chapter we will learn about using RingOpenGL 61.1 Samples Source (Authors) The samples in this chapter are based on C Tutorials from 1. http://www.lighthouse3d.com/tutorials/glut-tutorial/ 2. http://www.wikihow.com/Make-a-Cube-in-OpenGL 61.2 What is RingOpenGL? RingOpenGL contains the Ring binding to the OpenGL library You can learn about OpenGL from : https://www.opengl.org/ RingOpenGL comes with support for the next versions • OpenGL 1.1 • OpenGL 1.2 • OpenGL 1.3 • OpenGL 1.4 • OpenGL 1.5 • OpenGL 2.0 • OpenGL 2.1 • OpenGL 3.0 • OpenGL 3.2 • OpenGL 3.3 • OpenGL 4.0 • OpenGL 4.1 • OpenGL 4.2 • OpenGL 4.3 594
