立体声ARSCNview,使VR和AR混合

下面的代码基本上就是哈尔所说的。我之前在github上写了几行代码,可能可以帮助您入门。(代码简单,没有桶变形,没有对窄视场的调整-尚未)。

本质上,我们将同一场景连接到第二个ARSCNView(因此两个Arscn视图看到的是同一场景)。无需让ARWorldTrackingSessionConfiguration与2个ARSCNViews一起工作。然后,我们偏移它的视角,将其定位为第二只眼睛。

这个 ARSession documentation 他说

使用ARKit构建的每个AR体验都需要一个ARSession对象。如果您使用 ARSCNView 或

ARSCNView 实例,使用 SCNView 分享这首歌 在他们之间。

现在怎么做?

还有一个问题是,立体视觉需要两个稍微不同的摄像机位置,每只眼睛一个。ARKit使用一个摄像头,放置在iOS设备的位置,所以你必须对其进行模糊处理。

然后你必须处理每只眼睛不同的桶状失真。

对我来说,这相当于编写我自己的自定义对象来拦截ARKit代理消息,将坐标转换为我从两个不同摄像机看到的坐标,并管理两个不同的SCNViews(而不是ARSCNViews)。或者使用一个ARSCNView(一只眼睛),拦截其帧更新,并将这些帧传递给SCNView(另一只眼睛)。

把雷达归档,把号码贴出来,我会复制它。

import UIKit
import SceneKit
import ARKit

class ViewController: UIViewController, ARSCNViewDelegate {

    @IBOutlet weak var sceneView: ARSCNView!
    @IBOutlet weak var sceneView2: ARSCNView!

    override func viewDidLoad() {
        super.viewDidLoad()

        sceneView.delegate = self
        sceneView.showsStatistics = true
        let scene = SCNScene(named: "art.scnassets/ship.scn")!
        sceneView.scene = scene
        sceneView.isPlaying = true

        // SceneView2 Setup
        sceneView2.scene = scene
        sceneView2.showsStatistics = sceneView.showsStatistics

        // Now sceneView2 starts receiving updates
        sceneView2.isPlaying = true     
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        let configuration = ARWorldTrackingConfiguration()
        sceneView.session.run(configuration)
    }
    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        sceneView.session.pause()
    }
}

.isPlaying 两者的实例属性 ARSCNViews .

    //left
    leftSceneView = [ARSCNView new];

    leftSceneView.autoenablesDefaultLighting = true;
    [self.view addSubview:leftSceneView];

    rightSceneView = [ARSCNView new];

    [self.view addSubview:rightSceneView];

    //scene
    SCNScene * scene = [SCNScene new];
    leftSceneView.scene = scene;
    rightSceneView.scene = scene;

    //tracking
    ARWorldTrackingConfiguration * configuration = [ARWorldTrackingConfiguration new];
    configuration.planeDetection = ARPlaneDetectionHorizontal;
    [leftSceneView.session runWithConfiguration:configuration];
}

-(void)renderer:(id<SCNSceneRenderer>)renderer updateAtTime:(NSTimeInterval)time {

    dispatch_async(dispatch_get_main_queue(), ^{

        SCNNode * pov = self->leftSceneView.pointOfView.clone;

        SCNQuaternion orientation = pov.orientation;
        GLKQuaternion orientationQuaternion = GLKQuaternionMake(orientation.x, orientation.y, orientation.z, orientation.w);
        GLKVector3 eyePosition = GLKVector3Make(1, 0, 0);
        GLKVector3 rotatedEyePosition = GLKQuaternionRotateVector3(orientationQuaternion, eyePosition);
        SCNVector3 rotatedEyePositionSCNV = SCNVector3Make(rotatedEyePosition.x, rotatedEyePosition.y, rotatedEyePosition.z);

        float mag = 0.066f;
        float rotatedX = pov.position.x + rotatedEyePositionSCNV.x * mag;
        float rotatedY = pov.position.y;// + rotatedEyePositionSCNV.y * mag;
        float rotatedZ = pov.position.z;// + rotatedEyePositionSCNV.z * mag;
        [pov setPosition:SCNVector3Make(rotatedX, rotatedY, rotatedZ)];

        self->rightSceneView.pointOfView = pov;
    });
