This time, OpenGL is used to draw a circle, and a solid pentagram is drawn in the middle. 1. Draw solid five corners: Since the previous use of polygen painting will fail, maybe the GPU hardware will be different, so the use of polygen to draw a solid five-pointed star is not reliable; Therefore, polygen is not required to draw a star using a triangle. 2 circles Because there is no circular shape in glew, we can only manually set the vertex

Nested display list To support more complex plotting, the display list also supports nesting. That is, when creating a display list using glnewlist () or glcalllists () call the defined display list. Theoretically, the number of nested layers in the generated list can be 2 ^ 31-2, but in fact there are two reasons why this is not supported. First, when the number of nested layers increases, it takes a lot of resources and time to create a display list. Second, even if you can create multi-level

3. cars that do not look so similarLet's review the previous section. We have built a thin villain, but it does not seem satisfactory to us. In this section, we will introduce:① Construct a 3D scene, and the objects inside it are also three-dimensional. Our villain is also three-dimensional. If all the objects we construct look different More, we will consider using displaylist to display the list② Construct other 3D scenarios, and we can switch betwe

1. Coordinate Clipping In two-dimen1_space, The Clipping Region is the minimum and maximum x and y values that are inside the window. 2. viewport The viewport is the region with in the window's client area that is used for drawing the clipping area. The viewport simply maps the clipping area to region of the window. Loot: You can use viewports to shrink or enlarge the image inside the window and to display only a portion of the clipping area.

Problem description: there are now n ordered arrays in M groups, such as {1, 2, 3, 4}, {2, 3, 6}, {1, 3, 5, 7 }, select the data smaller than K in these arrays and return this value. Idea: Compare the minimum data selected each time by referring to the process of merging two Arrays 1. Define the selection position array index [m], initialized to 0 2. Find the Roc
