'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

Currently, OpenGL functions are mainly included in three libraries.1. GL function library2. Glu function library3. glut function library 1.

OpenGL functions-glbegin and glend Function prototype: Void glbegin(GlenumMode) Void glend(Void) Parameter description: Mode: Type of the created element. It can be the following value Gl_points: processes each vertex as a vertex. vertex N defines vertex N and draws n vertices in total. Gl_lines: Each vertex is used as an independent line segment. n lines are defined between the 2n-1 and 2n v

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. It can be used as a referenc

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

GLUTTutorial Prepare for transformation window 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
