Step 1 Creating a brush is relatively easy, but unless you know exactly what you want, even the most professional brushes won't help you. It's a snowy scene, of course, but what do we want? Perspective is very important for the reproduction of snow. It is not true that the whole scene is covered with white dots-it appears flat and unreal. To make snow more natural, we need to divide the scene

Hello everybody, today teaches everybody to do a very lifelike snow effect. Now start making. 1, open the Flash document, background layer is black, frame frequency is 20, new symbol for graphics, named Snowflake. 2, draw a snowflake in the graphic element, if dozen home oneself will draw the snowflake words completely may according to own hobby to draw, if will not see the drawing, I was draws with the line tool, the picture is the step. 3, draw a

1. Open a picture of the landscape taken in the snow in Photoshop as a background, as shown in Figure 1. 2. Create a new layer "Layer 1" and fill the layer with white. 3.

Avoid frequent redistribution One of the most admirable features of STL containers is that they can automatically grow enough to accommodate the data you put in, as long as they are not larger than their maximum size. (To know the maximum value, just call the member function named Max_size.) ） For vectors and strings, if more space is needed, the size is increased by a similar realloc thought. This realloc-like operation ha
