ObjectTarget Class¶
Inherits: Target
Description¶
ObjectTarget表示3D object target,它可以被 ObjectTracker 所跟踪。
ObjectTarget的大小由 obj 文件决定。可以通过修改 scale 达到修改size的目的。 scale 默认为1。
ObjectTarget通过 ObjectTracker.loadTarget 成功载入 ObjectTracker 之后可以被 ObjectTracker 检测和跟踪。

scale¶
模型的缩放比例。其值为模型在空间中的物理大小与在模型坐标系中的大小的比值,默认值为1。(假设模型坐标系中的标尺单位为米)

float easyar_ObjectTarget_scale(const easyar_ObjectTarget * This)
- C++17
float scale()
- C++03
float scale()
- Java
public float scale()
- Kotlin
fun scale(): Float
- Objective-C
- (float)scale
- Swift
public func scale() -> Float
- C#
public virtual float scale()
boundingBox¶
物体的包围盒,包括盒子的8个顶点。
顶点索引定义如下:
4-----7
/| /|
5-----6 | z
| | | | |
| 0---|-3 o---y
|/ |/ /
1-----2 x
- C
void easyar_ObjectTarget_boundingBox(easyar_ObjectTarget * This, easyar_ListOfVec3F * * Return)
- C++17
std::vector<Vec3F> boundingBox()
- C++03
void boundingBox(ListOfVec3F * * Return)

- Kotlin
fun boundingBox(): ArrayList<Vec3F>
- Objective-C
- (NSArray<easyar_Vec3F *> *)boundingBox
- Swift
public func boundingBox() -> [Vec3F]
- C#
public virtual List<Vec3F> boundingBox()
setScale¶
设置模型的缩放比例。设置之后会覆盖默认值以及在json文件中设的数值。其值为模型在空间中的物理大小与在模型坐标系中的大小的比值,默认值为1。(假设模型坐标系中的标尺单位为米)
还需要在渲染引擎中单独设置此模型缩放。
注意该设置需要在通过 ObjectTracker.loadTarget 载入 ObjectTracker 之前进行。
- C
bool easyar_ObjectTarget_setScale(easyar_ObjectTarget * This, float scale)
- C++17
bool setScale(float scale)
- C++03
bool setScale(float scale)
- Java
public boolean setScale(float scale)
- Kotlin
fun setScale(scale: Float): Boolean
- Objective-C
- (bool)setScale:(float)scale
- Swift
public func setScale(_ scale: Float) -> Bool
- C#
public virtual bool setScale(float scale)
runtimeID¶
获取target id。target id是运行时创建的整型数据,只有在成功的配置之后才是有效(非0)的。这个id是非0且全局递增的。

- Objective-C
- (int)runtimeID
- Swift
public override func runtimeID() -> Int32
- C#
public override int runtimeID()
uid¶
获取target uid。 ImageTarget 的uid在云识别算法中使用。在没有接入云识别的时候,你可以在json配置中设置这个uid,在自己的代码中作为另一种区分target的方法。

- C++17
std::string uid()

- Kotlin
fun uid(): String
- Objective-C
- (NSString *)uid
- Swift
public override func uid() -> String
- C#
public override string uid()

- C++03
void name(String * * Return)
- Java
public java.lang.@Nonnull String name()
- Kotlin
fun name(): String
- Objective-C
- (NSString *)name
- Swift
public override func name() -> String
- C#
public override string name()
setName¶
设置target名字。这个操作会覆盖上一次的设置或是服务器返回的数据。
- C

- C++17
void setName(std::string name)
- C++03

- Objective-C
- (void)setName:(NSString *)name
- Swift
public override func setName(_ name: String) -> Void

public override void setName(string name)
meta¶
获取setMetaData所设置的meta data。或者在云识别返回的target中,获得服务器所设置的meta data。
- C
void easyar_ObjectTarget_meta(const easyar_ObjectTarget * This, easyar_String * * Return)
- C++17
