when displaying an image, when it is larger than the enlarged original texture (gl_texture_mag_filter) or smaller than the original texture (gl_texture_min_filter) openGL adopts the filtering method. I usually use gl_linear in both cases. This allows the texture to be smoothly displayed from a very distance to a very close to the screen. Using gl_linear requires more operations on the CPU and video card. I

This chapter begins to learn how to use shader. In the past, many people often used OpenGL fixed pipelines to do some programs. shader is rarely used, while modern GPU programming and shader applications are indispensable. Although shader programming is used, A little more code, but more flexible.

'd like to tell you that people use cameras to observe things in 3D, although OpenGL does not actually have a camera. So when you move on the screen, you are actually moving all objects, and the feeling of motion is not caused by the creation of a camera to watch movies, instead, all objects in the world are moved with the relative coordinates (0, 0.
It sounds like this is a huge workload, but it is not. According to your application, you will perfor
(+) and minus (-) in the following code to see how the rotation direction of an object changes. And try to change 0.2 to 1.0. The larger the number, the faster the object is. The smaller the number, the slower the object is.
Rtri + = 0.2f; // increase the rotation variable of the triangle (new)Rquad-= 0.15f; // reduce the rotation variable of the Quadrilateral (new)Return true; // continue running}
Finally, change the title content in window mode.

Download the following vcpus and run the program (glu0.zip) (this is the project in the previous section ). You will see two windows: a console window and an OpenGL window. Change the window size so that the height and width are no longer equal, and the triangle is deformed. This occurs because you have not correctly set the projection matrix. The default value is the Perspective Projection Matrix and t
The code is not analyzed here because it is enough in the tutorial. If you are interested, you can check the code yourself. This tutorial comes from the original neheopengl Chinese tutorial (http://www.yakergong.net/nehe/), but it has a bad place, that is, when I go to see, it can not download the code ~~~~ Maybe my character is poor.

Lesson 1Texture ing of graphic fonts:
In this lesson, we will create a font with a texture based on the previous lesson, which is really simple.After publishing the first two tutorials on Bitmap fonts and contour fonts, I have received many emails. Many readers want to know how to assign texture maps to fonts. You can use the automatic texture coordinate generator. It generates texture coordinates for each polygon in the font.A small comment.
