They have another license terms. 25 | See license terms in each file. 26 | -------------------------------------------------------------------------------- /ReadMe.txt: -------------------------------------------------------------------------------- 1 | ### GLPaint ### 2 | 3 | ================================================================================ 4 | DESCRIPTION: 5 | 6 | The GLPaint sample application demonstrates how to support single finger painting using OpenGL ES. This sample also shows how to detect a "shake" motion of the device. 7 | 8 | By looking at the code you'll see how to set up an OpenGL ES view and use it for rendering painting strokes. The application creates a brush texture from an image by first drawing the image into a Core Graphics bitmap context. It then uses the bitmap data for the texture. 9 | 10 | To use this sample, open it in Xcode and click Build and Go. After the application paints "Shake Me", shake the device to erase the words. Touch a color to choose it. Paint by dragging a finger. 11 | 12 | NOTE: When you run the application in the simulator, you can use the Shake Gesture key under Hardware to simulate the shake motion. 13 | 14 | ================================================================================ 15 | BUILD REQUIREMENTS: 16 | 17 | iOS 7.0 SDK 18 | 19 | ================================================================================ 20 | RUNTIME REQUIREMENTS: 21 | 22 | iOS 5.0 or later 23 | 24 | ================================================================================ 25 | PACKAGING LIST: 26 | 27 | AppController.h 28 | AppController.m 29 | UIApplication's delegate class. 30 | 31 | PaintingViewController.h 32 | PaintingViewController.m 33 | The central controller of the application. Handles shake and other motion events. 34 | 35 | PaintingView.h 36 | PaintingView.m 37 | The class responsible for the finger painting. The class wraps the CAEAGLLayer from CoreAnimation into a convenient UIView subclass. The view content is basically an EAGL surface you render your OpenGL scene into. 38 | 39 | SoundEffect.h 40 | SoundEffect.m 41 | A simple Objective-C wrapper around Audio Services functions that allow the loading and playing of sound files. 42 | 43 | main.m 44 | The main entry point for the GLPaint application. 45 | 46 | Recording.data 47 | Contains the path used to display "Shake Me" after the application launches. 48 | 49 | Particle.png 50 | The texture used for the paint brush. 51 | 52 | ================================================================================ 53 | CHANGES FROM PREVIOUS VERSIONS: 54 | 55 | Version 1.13 56 | Updated for iOS 7 and 64-bit. 57 | 58 | Version 1.12 59 | Updated with OpenGL ES 2.0. Added a root view controller. Moved main controls from the UIApplication delegate to the new PaintingViewController class. Replaced the HSL2RGB() function with UIColor's +colorWithHue:saturation:brightness:alpha:. 60 | 61 | Version 1.11 62 | Updated to take into account the view's contentScaleFactor. 63 | Updated to draw strictly with premultiplied alpha pixel data. 64 | 65 | Version 1.9 66 | Upgraded project to build with the iOS 4.0 SDK. 67 | Fixed minor bugs. 68 | 69 | Version 1.8 70 | Removed duplicate lines in setting up OpenGL blending. 71 | 72 | Version 1.7 73 | Updated for iPhone OS 3.1. Set texture parameters before creating the texture. This will save texture memory and texture loading time. 74 | Use the shake API available in iPhone OS 3.0 and later. 75 | Made the sample xib-based. 76 | 77 | Version 1.6 78 | Updated for and tested with iPhone OS 2.0. First public release. 79 | 80 | Version 1.5 81 | Minor changes to the comments. 82 | There are no code changes in this version. 83 | 84 | Version 1.4 85 | Updated for Beta 6. 86 | Updated code to use revised EAGL API. 87 | Removed TouchView and Texture2D classes. 88 | Replaced the views used to choose brush color with a segmented control. 89 | Replace the Texture2D class with code that creates a texture using a Core Graphic bitmap graphics context. 90 | Speeded up the "Shake Me" instructions that appear at the start of the application. 91 | Revised touch handling to use the begin, moved, end, and cancelled methods instead of touchesChanged:withEvent; 92 | 93 | Version 1.3 94 | Updated for Beta 4. 95 | Changed project setting related to code signing. 96 | Replaced pixel buffer objects with framebuffer objects. 97 | 98 | Version 1.2 99 | Added an icon and a default.png file. 100 | 101 | Version 1.1 102 | Updated for Beta 2. 103 | 104 | ================================================================================ 105 | Copyright (C) 2009-2014 Apple Inc.
