3D透視應該阻止貨架等正確Scnview節點出現半透明
的ScnView的樣品圖像:
非常簡單。新增了Scnview。添加了Scnnodes(形狀和燈光)
使用標準Omni型燈。
爲什麼前面的物體沒有阻擋後面的物體?
下面的代碼:
[self.studioView addSubview:showTimeView];
showTimeView.frame = CGRectMake(self.paperView.frame.origin.x,
self.paperView.frame.origin.y,
self.paperView.frame.size.width,
self.paperView.frame.size.height);
SCNView *sceneView = (SCNView *)showTimeView;
sceneView.backgroundColor = [UIColor whiteColor];
sceneView.scene = [SCNScene scene];
SCNNode *root = sceneView.scene.rootNode;
sceneView.allowsCameraControl = YES;
sceneView.autoenablesDefaultLighting = NO;
// Add Camera
SCNNode *cameraNode = [SCNNode node];
cameraNode.camera = [SCNCamera camera];
cameraNode.position = SCNVector3Make(0, 0, 100);
cameraNode.eulerAngles = SCNVector3Make(0, -M_PI/8, 0);
cameraNode.camera.zNear = 0;
cameraNode.camera.zFar = thisModuleDepth;
cameraNode.camera.xFov = thisWallWidth;
cameraNode.camera.yFov = thisModuleHeight;
[root addChildNode:cameraNode];
// Add Cabinet Piece
SCNBox *cubeGeom = [SCNBox boxWithWidth:tW
height:tH
length:tD
chamferRadius:0.0];
SCNNode *cubeNode = [SCNNode nodeWithGeometry:cubeGeom];
cubeNode.position = SCNVector3Make(tX, tY, tZ);
// Tag Material
SCNMaterial *material = [SCNMaterial material];
material.diffuse.contents = [UIImage imageNamed:thisColor];
[material.diffuse.contents setAccessibilityIdentifier:thisColor] ;
[material.diffuse.contents setAccessibilityLabel:thisID] ;
cubeNode.geometry.firstMaterial = material;
cubeNode.geometry.firstMaterial.locksAmbientWithDiffuse = NO;
cubeNode.physicsBody = [SCNPhysicsBody staticBody];
[root addChildNode:cubeNode];
// Add spotlight
SCNLight *spotLight = [SCNLight light];
spotLight.type = SCNLightTypeOmni;
spotLight.color = [UIColor whiteColor];
SCNNode *spotLightNode = [SCNNode node];
spotLightNode.light = spotLight;
spotLightNode.position = SCNVector3Make(thisWallWidth/2 ,thisModuleHeight, thisModuleDepth *2);
spotLightNode.light.intensity = 1000;
[root addChildNode:spotLightNode];
你創建在Interface Builder或代碼SCNView?如果是後者,請提供。它看起來像你的場景已禁用深度測試,但我不認爲這是默認。 –
全部完成代碼...我只添加了IBOutlet SCNView * showTimeView來爲Interface Builder提取正確的視圖... – Juanra
