In the previous section, the RGB channel value of the texture is used as the grayscale to control the transparency of the pixel, which is called a semitransparent shader.This section learns the transparent clipping shader, still reads the RGB channel value, assigns it to Alpha, and then assigns a fixed value as the ruler, and if the Alpha This time the effect of the implementation is asSuitable as a monster to kill the effect.Transfer from Http://blog.csdn.net/huutu http://www.thisisgame.com.cnS

In OpenGL, support for vertex shaders and fragment shaders is required for proper rendering, and each frame in the vertex shader is processed once for each vertex of the object in the scene.If you use OpenGL yourself, you need to read the model data in C + + code, passing vertex coordinates, vertex colors, and UV coordinates to the vertex shader.So in a vertex shader, you can modify the vertex data.Build a test scenario and import the FBX model with t

So __new__ and __init__ are like such a relationship, __INIT__ provides the raw material for production self (but does not guarantee that this raw material source is authentic, like above it uses another unrelated class __new__ method class to get this instance), and __init__ uses __ NEW__ gives the raw material to refine this object (though it does not know whether these ingredients are authentic)If we do not want to initialize the instance with __init__ at all, we c

A function that accepts any number of arguments . When the number of arguments passed in a function is large, you do not need to define a variable for each parameter when the function is defined, and you can use *rest to include extra arguments. As the following code,*rest contains the 3 parameters of 2,3,4. And can iterate over the access. In this example,rest is actually a tuple of other positional parameters AVG (first,*rest):RestIaverage= (first+sum(rest))/(1+len(rest))AverageAVG (1,2,3,4

1. Implementation of matrix multiplication there are numpy.dot functions in numpy to handle multiplication between matrices: In [2]: a = Np.reshape (Np.arange (6), (2,3)) in [3]: b = Np.reshape (Np.arange (6), (3,2)) in [4]: Np.dot (A, B) Out[4]:array ([[10 , 13], [28, 40]]) But if we're going to implement matrix A * b * c * d, then writing three Numpy.dot is a little cumbersome. We can define a function Mdot (a,b,
