• Create a texture from CGImages
  

    - textureWithCGImage: options: error: load images from the Quartz 2D texture processing and image processing to create a new texture from data

    - textureWithCGImage: options: queue: completionHandler: Quartz 2D texture image processing asynchronous loading images and create a new texture processing according to data from.

• Create a multi-dimensional texture loaded from URL
  

    + CabeMapWithContentsOfURL: options: errer: load cube map texture image from a single URL, based on the data and create a new texture

    - cabeMapWithContentsOfURL: options: queue: completionHandler: load cube map texture image from a single asynchronous URL, and create a new texture based on the data

• Load files from multidimensional data file created textures
  

    + CubeMapWithContentsOfFile: options: errer: cube map texture object loaded from a single file, and create a new texture from data

    - cubeMapWithContentsOfFile: options: queue: completionHandler: Create a new texture from data from a single file is loaded asynchronously cube map texture object, and

    + CubeMapWithContentsOfFiles: options: errer: load cube map texture from a series of image files, and create a new texture from the total data

    - cubeMapWithContentsOfFiles: options: options: queue: completionHandler: Create a new texture from data from a series of files loaded asynchronously cube map texture image, and

GLKView using OpenGL ES rendering view the contents of the default implementation

• Initialization view

    - initWithFrame: context: initialize a new view

• proxy
  

    delegate views of proxy: - glkView: drawInRect: Drawing view contents (must implement agency)

• Configuration frame buffer objects
  

    drawableColorFormat color rendering buffer format

    drawableDepthFormat render depth buffer format

    drawableStencilFormat template rendering format buffer zone

    DrawableMultisample multiple format sample buffer zone

• Frame buffer properties
  

    Height drawableHeight underlying object cache (in pixels)

    Width drawableWidth underlying object cache (in pixels)

• Drawing view contents

    context: use when drawing down-view content files OpenGL ES
    - bindDrawable: Binding to the object underlying FrameBuffer OpenGL ES
    enableSetNeedsDisplay: Boolean value specifying whether the view so that the view of the contents of the response message Invalid
    - display: Immediately redraw the content view
    snapshot: Drawing view the content and returns it as a new image object

• Delete View bufferFrame objects
  

    - deleteDrawable delete the view associated with drawable

GLKViewController OpenGL ES rendering cycle management View Controller

• Update
  

    - (void) update update view contents

    - (void) glkViewControllerUpdate:

• Configuration frame rate

    preferredFramesPerSecond: View Controller calling view and update the contents of the view rate

    framesPerSencond: View Controller calling view and update the content of the actual rate

• Proxy Configuration GLKViewController

    Agent delegate view controller

           Update Event processing: - glkViewControllerUpdate: Use tone before displaying each frame

           Pause / Resume notification: - glkViewController: willPause: Using tune with before rendering cycle pause or resume.

• Update control frame

    paused boolean rendering loop has been suspended

    pausedOnWillResignActive Boolean value, the current view controller is automatically suspended rendering loop when the program re-stimulated active                                                                           

    View render loop control whether to automatically resume when resumeOnDidBecomeActive Boolean value, the current program becomes active

• View information about updating information

    frameDisplayed view controller update since its inception the number of frames sent

    The amount of time since the incident to send updates of timeSinceFirstResume view controller for the first time since the restoration                      

    TimeSinceLastResume the amount of time since the last update event view controller to resume sending updates            

    timeSinceLastUpdate view controller since the last adjustment, and Use by an amount of time elapsed delegate method glkViewControllerUpdate.:

    The amount of time that has elapsed since timeSinceLastDraw view display method since the last call to the view controller.

GLKBaseEffect ⼀ a simple light / discolored with color system, based on the discolored Using an OpenGL rendering shader

• Named Effect
  

    label to Effect (effect) named

• Configuration model view conversion

    Applied to the vertex data when the binding effect model view transform, projection transform, and texture

• Configuration lighting effects
  

    Use strategy for calculating lightingType light still pictures of each segment slightly, GLKLightingType

    GLKLightingType

            GLKLightingTypePerVertex denotes each vertex lighting calculations performed in the triangle, then the triangle interpolation

            GLKLightingTypePerPixel represents lighting calculations inserted in the input triangle, and each segment is calculated in the implementation of light

• Configuration of light

    lightModelTwoSided: Boolean value indicating the calculated illumination on both sides of the primitive

    material: calculated material properties rendering the primitive using light

    lightModelAmbientColor: ambient color, all drawing application effect of rendering yuan.

    light0: a first scene illumination property

    light2: third scene illumination properties

• Configuration texture
  

    texture2d0: The first texture attributes

    texture2d1: second texture properties

    textureOrder: textures to primitives rendering order

• Configuration atomization
