understand, now just need to know that this function can showwindow, and wait for the window to close before returning, which is enough. ）In the Glutdisplayfunc function, we set the "Call Mydisplay function when drawing is required." So the Mydisplay function isUsed for drawing. Observe the three function calls in Mydisplay and find that they all start with GL. This function, starting with GL, is OpenGL.Standard functions, the functions used are described below.1, Glclear, clear. Gl_color_buffe

Lesson 1Image Font: In this lesson, we will create some fonts Based on 2D images that can be scaled but cannot be rotated and always oriented to the front, but as a basic display, I think it is enough.Welcome to another tutorial. This time I will teach you how to use bitmap fonts. Maybe you will say to yourself, "What is the difficulty of displaying text on the screen ?". But once you try it, you will know that it is really not that easy. Of course, y

Lesson 1Expansion, cropping, and loading of TGA image files: In this lesson, you will learn how to read OpenGL extensions supported by your graphics card and display them in your specified cropping area.This tutorial is difficult, but it will help you learn a lot. I heard a lot of friends ask me about extensions and how to find them. This tutorial will be handed

OpenGL ES 08-do not use the mix color of mr. Bucket 1 Please note: I am not very satisfied with the status when I write this tutorial, so please do not care if you have any questions. If something goes wrong, don't worry. I will continue to explain it in section 2nd. Who is mr. Bucket? That's my kitchen mixer! (In English, mixer and mixed colors are the same.) Of course we are not talking about my kitchen m

Address: http://ogldev.atspace.co.uk/www/tutorial02/tutorial02.html When writing OpenGL programs, we usually need the glew library, which encapsulates various OpenGL extensions for our convenience. We can call the glew initialization function in the main function, and then we can query whether OpenGL extensions can be used. For functions that can be used, we can

); // rotate along the Z axisThe following is an exciting color loop. As usual, we use the unique incremental variable (ROT ). Color changes cyclically by using COs and sin. I divide the rot by different numbers so that each color increases at a different speed. The final result is very good.// Set the color based on the font positionGlcolor3f (1.0f * float (COS (ROT/20366f), 1.0f * float (sin (ROT/25366f )), 1.0f-0.5f * float (COS (ROT/172.16f )));Write text to the screen in my favorite part.
