. Most mainstream commercially available games are developed based on DirectX, for example, popular outstanding games such as the times of Empire 3, the spirit of the island, Call of Duty 2, and Half Life2. Currently, OpenGL is mainly used in professional graphics workstations. It has been used to compete with DirectX in the history of games and has produced a large number of excellent Games, for example, t

The function prototypes are:void Glutinit (int argc,char **argv);You can then set some properties of glut.Configuring Display Propertiesvoid Glutinitdi

The main actions that OpenGL performs when rendering images in a scene:1. Create a shape from a geometry to establish a mathematical description of the object (OpenGL puts points, lines, polygons, and bitmaps as basic primitives)2. Arrange the objects in three-dimensional space and choose to observe the perspective in

This time I will study the Code with the I2C driver in the kernel. Before going into the code, I will first briefly understand the relationship between the I2C core data structure. From this, we may be able to have a better understanding of the driver code. The design of the software data structure and the relationship between the data structures should at least describe the Organizational Relationship of t
