大家好，我试图实现一个功能，用户可以在一个场景视图的2D和3D可视化之间改变(有点像谷歌地图允许做的事情)。我旋转屏幕的方式是基于投影在地面上的SceneView中心点，这显然不是理想的。这就产生了一个问题，当用户旋转屏幕时，屏幕的中心不会碰到地面，在这种情况下，我必须根据当前相机位置手动旋转，这就产生了一种奇怪的用户体验。我将提供代码，如果有人知道更好的方法，请分享，这将非常感谢。非常感谢!FloatingActionButton change2D3DView = findViewById(R.id.change2D3DView);change2D3DView。setOnClickListener(new View. onclicklistener () {@Override public void onClick(View v) {float centreX = mSceneView.getX() + mSceneView.getWidth() / 2;float centreY = mSceneView.getY() + mSceneView.getHeight() / 2;android.graphics.Point screenPoint = new android.graphics.Point(Math.round(centreX)， Math.round(centreY)); Point mapPoint = mSceneView.screenToBaseSurface(screenPoint); // In case the center of the screen does not hit ground if (mapPoint == null) { Point groundLevel = new Point(mSceneView.getCurrentViewpointCamera().getLocation().getX(), mSceneView.getCurrentViewpointCamera().getLocation().getY(), 0.0, SpatialReferences.getWgs84()); // Turn to 2D - pitch a 0 mOrbitLocationCameraController = new OrbitLocationCameraController(groundLevel, 2000); mSceneView.setCameraController(mOrbitLocationCameraController); // Get current pitch angle double currentPitch = mSceneView.getCurrentViewpointCamera().getPitch(); mOrbitLocationCameraController.moveCameraAsync(0, 0, (0.0 - currentPitch), 1f).addDoneListener(new Runnable() { @Override public void run() { mSceneView.setCameraController(new GlobeCameraController()); map_2d_mode = true; } }); return; } Point tempGroundLevel = (Point) GeometryEngine.project(mapPoint, SpatialReferences.getWgs84()); Point groundLevel = new Point(tempGroundLevel.getX(), tempGroundLevel.getY(), 0.0, SpatialReferences.getWgs84()); if (map_2d_mode) { // Turn to 3D - set pitch to 45 // Get current pitch angle double currentPitch = mSceneView.getCurrentViewpointCamera().getPitch(); Camera newCamera = mSceneView.getCurrentViewpointCamera().rotateAround(groundLevel,0, ((45.0 - currentPitch) < 0.0) ? 0.0 : (45.0 - currentPitch), 0); mSceneView.setViewpointCameraAsync(newCamera, 0.7f).addDoneListener(new Runnable() { @Override public void run() { map_2d_mode = false; } }); } else { // Turn to 2D - set pitch to 0 // Get current pitch angle double currentPitch = mSceneView.getCurrentViewpointCamera().getPitch(); Camera newCamera = mSceneView.getCurrentViewpointCamera().rotateAround(groundLevel,0, (0.0 - currentPitch), 0); mSceneView.setViewpointCameraAsync(newCamera, 0.7f).addDoneListener(new Runnable() { @Override public void run() { map_2d_mode = true; } }); } } }); ．.．查看更多

嘿，大家好，我试图在Nexus 6 API 26模拟器上“显示一个场景”示例应用程序，但得到下面的错误。我尝试将“模拟器性能”更改为“软件- GLES 2.0”，并将模拟器RAM增加到3072Mb，但没有效果。任何见解都将非常感激。Cheers E/AndroidRuntime: FATAL EXCEPTION:渲染线程进程:com.example。a2d3d_test_app, PID: 8020 com.esri.arcgisruntime.ArcGISRuntimeException:内部错误。：Failed to compile GL Shader: tile_3d_draw_ps Error Log: WARNING: 0:2: 'GL_EXT_frag_depth' : extension is not supported ERROR: 0:254: 'gl_FragDepthEXT' : undeclared identifier at com.esri.arcgisruntime.internal.jni.CoreGeoView.nativeDraw(Native Method) at com.esri.arcgisruntime.internal.jni.CoreGeoView.a(SourceFile:5) at com.esri.arcgisruntime.a.i.f.g.a(SourceFile:87) at com.esri.arcgisruntime.mapping.view.GeoView$RenderingThread.draw(SourceFile:2) at com.esri.arcgisruntime.mapping.view.SceneView.b(SourceFile:1) at com.esri.arcgisruntime.mapping.view.SceneView.lambda$moyPL0flTCRthLMFyvD_1llgzxc(Unknown Source:0) at com.esri.arcgisruntime.mapping.view.-$$Lambda$SceneView$moyPL0flTCRthLMFyvD_1llgzxc.a(Unknown Source:2) at com.esri.arcgisruntime.internal.jni.CoreGeoView.onDrawRequested(SourceFile:4) at com.esri.arcgisruntime.internal.jni.CoreGeoView.nativePulse(Native Method) at com.esri.arcgisruntime.internal.jni.CoreGeoView.z(SourceFile:1) at com.esri.arcgisruntime.a.i.f.g.o(SourceFile:1) at com.esri.arcgisruntime.mapping.view.GeoView$RenderingThread.doFrame(SourceFile:3) at android.view.Choreographer$CallbackRecord.run(Choreographer.java:909) at android.view.Choreographer.doCallbacks(Choreographer.java:723) at android.view.Choreographer.doFrame(Choreographer.java:655) at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:897) at android.os.Handler.handleCallback(Handler.java:789) at android.os.Handler.dispatchMessage(Handler.java:98) at android.os.Looper.loop(Looper.java:164) at com.esri.arcgisruntime.mapping.view.GeoView$RenderingThread.run(SourceFile:5) ．.．查看更多
