ARViewStyles ================================================================================ ABSTRACT: This project demonstrates the different ways to implement and use the augmented reality (AR) library in the SGiPhoneSDK. The library is completely independent from the SGLocationService. Different Styles: 1. Default - This is just the default style. SGAnnotationView are present as red pins while the radar mantains its default images. When pins are touched, the default inspect behavior occurs where the view is removed from the AR enviornment and then added as a subview of the ARView. 2. Forest - This style sets the SGAnnotationViews into inspect mode while being present in the AR enviornment. It can be considered to be the reverse of the default style. When the SGAnnotationView is touched, it is removed from the AREnvironment, placed into, target mode and then added as a subview of the SGARView. 3. Damsels in Distress - There are two types of SGAnnotationViews used here. One with a static position and another that changes everytime the SGAnnotationView needs to be redrawn. The main note to take away from this style is that SGAnnotationViews can move around within the AR enviornment and still be represented properly by the radar. 4. Kettle + Escher - SGAnnotationViews allow subclasses to draw themselves in OpenGLES. Instead of setting up the subview layout, we just load in the teapot vertices and normals and we are able to draw the teapot model in the proper location. Note: At the moment this is throw-away code. Plans to make things nice-and-pretty will happen very soon. ================================================================================ BUILD REQUIREMENTS: iPhone SDK 3.1 Frameworks - CoreLocation - Foundation - MapKit - OpenGLES - CoreGraphics - UIKit ================================================================================ RUNTIME REQUIREMENTS: iPhone OS 3.1 iPhone 3GS (Nothing particularly exciting happens when running it in the simulator) ================================================================================ PACKAGING LIST: SGARViewStylesAppDelegate Standard AppDelegate implementation. Once the applicationDidFinishLaunching: is called, the SGStylesViewController is added to the main window. SGStylesViewController This is the main view controller for the application; it is in charge of configuring styles and loading the AR enviornment. Each style is setup using there own configuration method, see #pragma Style config methods. Since there is no reset button for the AR enviornment, each setting must be addressed in order to produce the proper style. SGSimpleAnnotation A simple class that implements the SGAnnotation protocol. Its used to provide a title and subtitle for SGAnnotationViews when they are inspected. SGForestAnnotationView Initalizes the SGAnnotationView with a randomly chosen forest critter and then uses one of the view properties (distance, coordinate or bearing) to display as the title while in inspect mode. SGDistressedDamselAnnotationView Setups up the SGAnnotationView to have the glassy style along with a random princess to be used as the target image. SGKettleAnnotationView This SGAnnotationView draws itself. By setting enableOpenGL to YES and implementing drawAnnotationView, we are able to render a model at the proper location in the AR enviornment. The AR library will ask to SGAnnotationView to draw itself at the origin. It will then apply the proper transformations to place the model inside the enviornment. SGGargoyleAnnotaitonView A random scary SGAnnotationView that increments its position in the AR enviornment. It does something tricky though. It overrides the annotation get property and does some readjustment to the coordinate. Everytime the view needs to be drawn, the annotaiton is accessed to obtain the coordinate of the view. ================================================================================ CHANGES FROM PREVIOUS VERSIONS: Version 0.9.4 - Upgraded to use the public release of the AREnvironment Version 0.9.3 - Added license Version 0.9.2 - Updated project structure to use the new static libraries Version 0.9.1 - Updated to v0.3.0 of the SDK Version 0.9.0 - Added icon and iTunesArtwork. - Updated the SDK to v0.2.3 Version 0.8.1 - Added more comments to the code.
