The state management mechanism of OpenGL Viewport and viewport coordinate system concepts Test Viewport settings 1 Moving the Viewport 2 Multi-viewport Viewport summary 1 status management mechanism for OpenGLAs we can see from the simplest examples above, we have almost no configuration of colors and coordinate systems, and OpenGL has been able to implement rendering

In this section, we will study the development environment of OpenGL in WIN10 64 and VS1013 environment.(1) Select a compilation environment:Now the main compiler tools for OpenGL in Windows are visual Studio,broland C + + Builder,dev C + +, we choose Visual Studio2013 as the development environment.(2) Resources used:We used the three libraries of Glew,freeglut and Gltools . Here is an introduction to them

2.1 basic understanding of OpenGL OpenGL is a software interface with a hardware Graphics Generator. It includes more than 100 graphic operation functions. developers can use these functions to construct scene models and develop 3D graphics interaction software. As described in the previous chapter, OpenGL is a high-performance graphics development software packa

The following article details the conversion of coordinates in OpenGL, which is clear and unambiguous. But the so-called rendering pipeline includes only Modelview transformations and projection transformations, which I think is not the case. That's just the angle of the coordinates. For example, what vertex coloring, rasterization, sent to the frame cache are not involved. Original address: http://blog.csdn.net/zhulinpptor/article/details/5897102 1.

the upper-left corner. In OpenGL, the object surface coordinates range from 1 to 1. The coordinate system origin is in the center position. the process of OpenGL video display Knowledge of textures has been documented in the article "simplest AV playback example 4:direct3d playback RGB (via texture)". The concept of textures in OpenGL is essentially equivalent

Before opengl2.0, OpenGL was designed as a fixed-function state machine, so the only way to modify OpenGL was to define extensions for it. In this way, in various OpenGL implementations, new functions should be exposed in the form of extensions, resulting in a large number of available extensions. OpenGL has a well-def

Nine, OpenGL colorAlmost all OpenGL applications aim to draw color graphics within the screen window, so color plays an important role in OpenGL programming. The color here is not the same as the color concept in painting, it belongs to the RGB color space and is only displayed on the monitor screen. In addition, the screen window coordinates are in pixels, so ea

Install The first indispensable thing is the compiler and the basic library. if the system is not installed, install it as follows: $ sudo apt-get install build-essential Install OpenGL Library $ sudo apt-get install libgl1-mesa-dev Install

1 representation of 3D objects in OpenGL In 3D space, a scene is a collection of objects or models. In 3D rendering, all objects are composed of triangles. This is because a triangle can represent a plane, and a 3D object is composed of one or more planes. For example, it represents a very complex 3D terrain, and its door is represented by many triangles. Terrain after rendering Complex terrain is also composed of triangles.
