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。

Java

public static @Nullable ObjectTarget createFromObjectFile(java.lang.@Nonnull String path, int storageType, java.lang.@Nonnull String name, java.lang.@Nonnull String uid, java.lang.@Nonnull String meta, float scale)

Kotlin

companion object fun createFromObjectFile(path: String, storageType: Int, name: String, uid: String, meta: String, scale: Float): ObjectTarget?

Objective-C

+ (easyar_ObjectTarget *)createFromObjectFile:(NSString *)path storageType:(easyar_StorageType)storageType name:(NSString *)name uid:(NSString *)uid meta:(NSString *)meta scale:(float)scale

Swift

public static func createFromObjectFile(_ path: String, _ storageType: StorageType, _ name: String, _ uid: String, _ meta: String, _ scale: Float) -> ObjectTarget?

C#

public static Optional<ObjectTarget> createFromObjectFile(string path, StorageType storageType, string name, string uid, string meta, float scale)

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)

C

float easyar_ObjectTarget_scale(const easyar_ObjectTarget * This)

C++

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++

std::vector<Vec3F> boundingBox()

Java

public java.util.@Nonnull ArrayList<@Nonnull Vec3F> boundingBox()

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++

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。

C

int easyar_ObjectTarget_runtimeID(const easyar_ObjectTarget * This)

C++

int runtimeID()

Java

public int runtimeID()

Kotlin

fun runtimeID(): Int

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++

std::string uid()

Java

public java.lang.@Nonnull String uid()

Kotlin

fun uid(): String

Objective-C

- (NSString *)uid

Swift

public override func uid() -> String

C#

public override string uid()

name

获取target名字。名字用来在json文件中区分target。

C

void easyar_ObjectTarget_name(const easyar_ObjectTarget * This, easyar_String * * Return)

C++

std::string name()

Java

public java.lang.@Nonnull String name()

Kotlin

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

void easyar_ObjectTarget_setName(easyar_ObjectTarget * This, easyar_String * name)

C++

void setName(std::string name)

Java

public void setName(java.lang.@Nonnull String name)

Kotlin

fun setName(name: String): Unit

Objective-C

- (void)setName:(NSString *)name

Swift

public override func setName(_ name: String) -> Void

C#

public override void setName(string name)

meta
