Class ObjectTarget

Namespace

easyar

ObjectTarget represents a 3D object target, which can be tracked by ObjectTracker. The size of ObjectTarget is determined by the obj file. You can modify the size by changing scale, which defaults to 1. After ObjectTarget is successfully loaded into ObjectTracker through loadTarget, it can be detected and tracked by ObjectTracker.

scale

The scale of the model. Its value is the ratio of the physical size of the model in space to the size in the model coordinate system, with a default value of 1. (Assuming the scale unit in the model coordinate system is meters)

• java
• kotlin
• objective-c

float easyar_ObjectTarget_scale(const easyar_ObjectTarget * This)

float scale()

public float scale()

fun scale(): Float

- (float)scale

public func scale() -> Float

public virtual float scale()

Returns

Single

boundingBox

The bounding box of the object, including 8 vertices of the box. The vertex indices are defined as follows:

  4-----7
 /|    /|
5-----6 |    z
| |   | |    |
| 0---|-3    o---y
|/    |/    /
1-----2    x

• c
• cpp
• java
• kotlin
• objective-c
• swift
• csharp

void easyar_ObjectTarget_boundingBox(easyar_ObjectTarget * This, easyar_ListOfVec3F * * Return)

std::vector<Vec3F> boundingBox()

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

fun boundingBox(): ArrayList<Vec3F>

- (NSArray<easyar_Vec3F *> *)boundingBox

public func boundingBox() -> [Vec3F]

public virtual List<Vec3F> boundingBox()

Returns

List<Vec3F>

setScale

Set the scale of the model. After setting, it will overwrite the default value and the value set in the json file. Its value is the ratio of the physical size of the model in space to the size in the model coordinate system, with a default value of 1. (Assuming the scale unit in the model coordinate system is meters) This model scale also needs to be set separately in the rendering engine. Note that this setting needs to be done before loading into ObjectTracker through loadTarget.

bool easyar_ObjectTarget_setScale(easyar_ObjectTarget * This, float scale)

bool setScale(float scale)

public boolean setScale(float scale)

fun setScale(scale: Float): Boolean

- (bool)setScale:(float)scale

public func setScale(_ scale: Float) -> Bool

public virtual bool setScale(float scale)

Parameters

scale Single

Returns

Boolean

runtimeID

Get the target id. The target id is an integer data created at runtime and is valid (non-zero) only after successful configuration. This id is non-zero and globally increasing.

• objective-c
• swift
• csharp
