The difference between double cache and single cache When encoding, I encounter glutInitDisplayMode(unsigned int mode); function, the main function is to set the initial display mode, and there are two available parameters that are not well understood. They are GLUT_SINGLE, GLUT_DOUBLE. Where GLUT_SINGLE specifies a single cache window and GLUT_DOUBLE specifies a double cache window. The difference between a double-cache window and a single-cache window must be understood here. Single cache window: In fact, all the drawing instructions are executed on the window, which is directly drawn on the window. The drawing efficiency is relatively slow. If you use single buffer and the computer is slow, you will see the screen flicker. . Single cache window: In fact, all the drawing instructions are executed on the window, which is directly drawn on the window. The drawing efficiency is relatively slow. If you use single buffer and the computer is slow, you will see the screen flicker. . Double-buffer window: The actual drawing instruction is completed in a buffer. The drawing here is very fast. After the drawing instruction is completed, the completed graphic is immediately displayed on the screen by the exchange instruction, which avoids the drawing. Incomplete and efficient. How to use it? Generally, OpenGL drawing is double buffered, and single buffering is generally only used to display a single non-dynamic image.
