我正在尝试使用纹理创建包含SCNScene的pod并出现错误:
SceneKit Error: Failed loading : C3DImage
src:file:///Users/.../Example.app/Templates.scnassets/grid.png
纹理和场景位于同一个文件夹中。
我尝试加载SCNSceneSource
let sceneData = try Data(contentsOf: sceneUrl)
let options = [.overrideAssetURLs: true,
.assetDirectoryURLs: MYPod.bundle().bundleURL
] as [SCNSceneSource.LoadingOption : Any]
let source = SCNSceneSource(data: sceneData, options:options)
scene = (source?.scene(options: options))!
但结果相同(路径不变)
答案 0 :(得分:2)
您应该使用代码和所有材料(对于伪代码抱歉)
for i in range(1,exp.shape[1]):
minIndex = max(bestIndeces[i-1]-maxIndexDelta,0)
maxIndex = min(bestIndeces[i-1]+maxIndexDelta, 2499)
SR = np.power(cal[:,minIndex:maxIndex]-exp[:,[i]],2)
SSR = np.sum(SR,axis=0)
bestSSRs[i] = np.min(SSR)
bestIndeces[i] = int(np.argmin(SSR) + minIndex)
