Simon iPhone-OpenGL ES tutorial-04 OpenGL ES 04-color and texture As my last tutorial said, I'm tired of drawing white objects on the screen, so that we can add some colors, just like the project automatically generated by the apple module. Next I will introduce you to pay attention to these concepts, because these co

final Texture unit color based on the texture coordinates, and combine these colors with the color of the dot element or the color calculated based on the illumination to output the final color of the pixel. In the following tutorial, we will see that the Texture unit can contain different data and implement many special effects. OpenGL supports 1d, 2d, 3D, cube, and many other textures, which are used in

Because of work, I don't have much time to focus on game development. Here we will list some previously collected OpenGL tutorials and share them with friends who like OpenGL and game development. Of course, there are still some good tutorial websites not included in it. You are welcome to add that the title "Top Ten" is completely designed to attract everyone's

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

Guidance: Modern OpenGL Tutorial 01--Getting Started GuideIn this article, we'll add a map to the triangle, which involves adding some new variables to the vertex and fragment shader, creating and using the mapped object, and learning a bit about the mapping unit and mapping coordinates.This article uses two new classes into the Tdogl namespace: Tdogl:bitmap and Tdogl:texture. These classes allow us to uplo

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

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.
