pointers should have the ownership of the COM component. As follows:
View plaincopy to clipboardprint? CComPtr HRESULT hr = spIX. CoCreateInstance (CLSID_MYCOMPONENT );If (SUCCEEDED (hr )){SpIX-> Fx ();CComPtr SpIX2-> Fx ();SpIX-> Fx (); // After the value assignment operation, the original smart pointer can still be used.} // When the smart pointer structure is

, the above state can also be optimized: Notice that the position of the special block only changes when it is exchanged with the white block, so we only use record F[X][Y][FX] f[x][y][fx], which represents the coordinates of the special block and a bearing (up and down), which represents the position of the white block in the special block. Thus, in order to simulate a special block move, we also preproce
on gradient descent method
If the reader's guide number and gradient definitions are not well understood, read the previous article, "Number of square guides and gradients."
Prior to the machine learning, it was found that the gradient descent method was the most important one in machine learning. The gradient descent algorithm process is as follows:
1) Random initial value;
2) iterate until it converges. Indicates the negative gradient direction at the place, indicating the learning rate.

hello,structs!
In this section, Helloshaders effect is rewritten using the C-style structure. The use of data structures can better organize multiple shader inputs and outputs than a single parameter. First create a new effect and material in the Nvidia FX composer, just as this chapter starts by adding effect using the Add Effect Wizard. Or a simple copy helloshaders.fx into a new file hellostructs.fx. I prefer the second option because it is often

Import shader to your engine
Thanks to DirectX and xNa, it is easy to load the FX file and set all required parameters (you have done this in the previous chapter when drawing 2D and 3D straight lines ). In the next chapter, you will use a more general class, which can accept many different shader and set all required parameters in a more optimized way, however, this chapter only uses simpleshader in the engine.
