我是 Tango 的新手，无法在 Project Tango 中使用 Rajawali。
有没有办法在单击事件发生时将新对象动态添加到 CurrentScene 上？
我尝试过getCurrentScene().addChild(object)在 addNote() 函数中使用，每当单击事件发生时都会调用该函数。
每当调用 addNote() 时，场景的子节点数就会增加，但视觉场景不会更新。</p>
这是我的代码：
public class SampleRenderer extends TangoRajawaliRenderer {
public SampleRenderer(Context context) {
super(context);
}
@Override
protected void initScene() {
// Remember to call super.initScene() to allow TangoRajawaliArRenderer to set-up
super.initScene();
// Add a directional light in an arbitrary direction
DirectionalLight light = new DirectionalLight(1, 0.2, -1);
light.setColor(1, 1, 1);
light.setPower(0.8f);
light.setPosition(3, 2, 4);
getCurrentScene().addLight(light);
// Set-up a material: green with application of the light
Material material = new Material();
material.setColor(0xff009900);
material.enableLighting(true);
material.setDiffuseMethod(new DiffuseMethod.Lambert());
// Build a pyramid and place it roughly in front and a bit to the right
Object3D object1 = new NPrism(4, 0f, 0.2f, 0.2f);
object1.setMaterial(material);
object1.setPosition(-0.25, 0, -1);
getCurrentScene().addChild(object1);
Log.d("Tap", getCurrentScene().getNumChildren() + "");
}
public void addNote(float x, float y, float z){
Material stickyNoteMaterial = new Material();
stickyNoteMaterial.setColor(0xEFF2B900);
stickyNoteMaterial.enableLighting(true);
stickyNoteMaterial.setDiffuseMethod(new DiffuseMethod.Lambert());
Object3D note = new Sphere(0.1f, 24, 24);
note.setMaterial(stickyNoteMaterial);
note.setPosition(x, y, z);
getCurrentScene().addChild(note);
Log.d("Tap", getCurrentScene().getNumChildren() + "");
}
@Override
public void onOffsetsChanged(float xOffset, float yOffset, float xOffsetStep, float yOffsetStep, int xPixelOffset, int yPixelOffset) {
}
@Override
public void onTouchEvent(MotionEvent event) {
}
}
提前致谢！
