Question

所以我有6个单独的图像，我想用它们构建一个textureCube。什么是最好的方法呢？现在这就是我所拥有的，但是当TextureCube尝试创建自己时，我得到了内存访问冲突。

SharpDX.DataBox[] textureData = new SharpDX.DataBox[6];
for(int i = 0; i < 6; i++)
{
    Texture2D tex = Texture2D.Load(device, resources[i].Filepath);
    SharpDX.Direct3D11.Texture2D staged = (SharpDX.Direct3D11.Texture2D)tex.ToStaging();
    textureData[i] = new SharpDX.DataBox(staged.NativePointer, staged.Description.Width, 0);
}

SharpDX.Toolkit.Graphics.TextureCube cube = SharpDX.Toolkit.Graphics.TextureCube.New(
            device,
            2048,
            PixelFormat.R8G8B8A8.UNorm,
            textureData);

纹理负载工作正常。我可以加载纹理，然后从单个图像创建一个textureCube没问题。但这并没有多大用处。当我尝试使用来自我的6个单独图像的原始数据创建一个立方体时，我得到了内存异常。
