示例1: CheckTexture
private void CheckTexture(GraphicsContext graphicsContext, Texture texture, byte[] data)
{
// Get back the data from the gpu
var data2 = texture.GetData<byte>(graphicsContext.CommandList);
// Assert that data are the same
Assert.That(Utilities.Compare(data, data2), Is.True);
// Sets new data on the gpu
data[0] = 1;
data[31] = 255;
texture.SetData(graphicsContext.CommandList, data);
// Get back the data from the gpu
data2 = texture.GetData<byte>(graphicsContext.CommandList);
// Assert that data are the same
Assert.That(Utilities.Compare(data, data2), Is.True);
