SCNAssimpScene Class Reference

Inherits from	SCNScene
Declared in	SCNAssimpScene.h SCNAssimpScene.m

Overview

A scene graph—a hierarchy of nodes with attached geometries, lights, cameras and other attributes that together form a displayable 3D scene.

This scene graph is generated by parsing a scene graph that represents a file loaded with the assimp library.

SCNScene objects

`modelScene`

The scene representing the mdoel and the optional skeleton.

@property (readonly, nonatomic) SCNScene *modelScene

Discussion

The scene representing the mdoel and the optional skeleton.

Declared In

SCNAssimpScene.h

`animationScenes`

The array of scenes where each scene is a skeletal animation.

@property (readonly, nonatomic) NSDictionary *animationScenes

Discussion

The array of scenes where each scene is a skeletal animation.

Declared In

SCNAssimpScene.h

Animation data

`skeletonNode`

The root of the skeleton.

@property (readwrite, nonatomic) SCNNode *skeletonNode

Discussion

The root of the skeleton.

Declared In

SCNAssimpScene.h

`animations`

The dictionary of SCNAssimpAnimation objects, for each animation in the scene.

@property (readonly, nonatomic) NSMutableDictionary *animations

Discussion

The dictionary of SCNAssimpAnimation objects, for each animation in the scene.

Declared In

SCNAssimpScene.h

Creating a new scene animation

`– init`

Creates a new scene animation, without any animation data.

- (id)init

Return Value

A new scene animation object.

Discussion

Creates a new scene animation, without any animation data.

Declared In

SCNAssimpScene.h

Add, fetch SCNAssimpAnimation animations

`– animationForKey:`

Return the SCNAssimpAnimation object for the specified animation key.

- (SCNAssimpAnimation *)animationForKey:(NSString *)key

Parameters

`key`	The unique scene animation key.

Return Value

The scene animation object.

Discussion

Return the SCNAssimpAnimation object for the specified animation key.

Declared In

SCNAssimpScene.h

`– addAnimation:toScene:`

Adds an SCNAssimpAnimation object to the given scene.

- (void)addAnimation:(SCNAssimpAnimation *)assimpAnimation toScene:(SCNScene *)animScene

Parameters

`assimpAnimation`	The scene animation object created from the animation data.
`animScene`	The scene to which the animation object is added.

Discussion

Adds an SCNAssimpAnimation object to the given scene.

Declared In

SCNAssimpScene.m

Add, fetch scene animations

`– animationKeys`

Return the keys for all the animations in this file.

- (NSArray *)animationKeys

Return Value

The array of animation keys.

Discussion

Return the keys for all the animations in this file.

Declared In

SCNAssimpScene.h

`– animationSceneForKey:`

Return the SCNScene object for the specified animation key.

- (SCNScene *)animationSceneForKey:(NSString *)key

Parameters

`key`	The unique scene animation key.

Return Value

The scene animation object.

Discussion

Return the SCNScene object for the specified animation key.

Declared In

SCNAssimpScene.h

`– makeModelScene`

Makes the SCNScene representing the model and the optional skeleton.

- (void)makeModelScene

Discussion

Makes the SCNScene representing the model and the optional skeleton.

This transformation to SCNScene allows the client to use the existing SCNScene API. This also makes it trivial to support serialization using the existing SCNScene export API, thereby allowing easy integration in the XCode Scene editor and the asset pipeline.

Declared In

SCNAssimpScene.h

`– makeAnimationScenes`

Makes an array of SCNScene objects, each SCNScene representing a skeletal animation.

- (void)makeAnimationScenes

Discussion

Makes an array of SCNScene objects, each SCNScene representing a skeletal animation.
