我是SceneKit
中的新產品,使用swift 3
和最新的Vuforia
庫6-2-9。Sceneikit使用Vuforia AR庫定製型號
我在自定義3D模型上應用textures
時遇到問題。
fileprivate func createDefaultMarkerScene(with view: VuforiaEAGLView) -> SCNScene {
let scene = SCNScene()
let lightNode = SCNNode()
lightNode.light = SCNLight()
lightNode.light?.type = .omni
lightNode.light?.color = UIColor.lightGray
lightNode.position = SCNVector3(x: 0, y: 0, z: 1000)
scene.rootNode.addChildNode(lightNode)
let ambientLightNode = SCNNode()
ambientLightNode.light = SCNLight()
ambientLightNode.light?.type = .ambient
ambientLightNode.light?.color = UIColor.darkGray
scene.rootNode.addChildNode(ambientLightNode)
let geoNode = SCNNode()
geoNode.name = "model_model"
let normalsSources = SCNGeometrySource(normals: normalsSCNVector3)
let verticesSources = SCNGeometrySource(vertices: verticesSCNVector3)
let texCoordsSources = SCNGeometrySource(textureCoordinates: texCoordCGPoint)
let indicesElements = SCNGeometryElement(indices: indices, primitiveType: SCNGeometryPrimitiveType.triangles)
geoNode.geometry = SCNGeometry(sources: [verticesSources, normalsSources, texCoordsSources], elements: [indicesElements])
geoNode.position = SCNVector3(x: 0, y: 0, z: 0)
geoNode.scale = SCNVector3(x: 50, y: 50, z: 50)
let material = SCNMaterial()
material.diffuse.contents = UIImage(named: "grad_ao.png")
geoNode.geometry?.firstMaterial = material
scene.rootNode.addChildNode(geoNode)
return scene
}
模型被正確渲染,但應用的紋理完全搞砸了。我已經嘗試過旋轉圖像,也uv座標一切ok [0..1]。
任何想法?謝謝
