OpenGL extensions is one of the highlights of OpenGL. The update of the video card brings more and more dazzling new features, so that we can use the outstanding hardware to draw amazing 3D images. With the extension mechanism of OpenGL, new features provided by any hardware manufacturer can be conveniently used by our OpenGL

Array Operations for demonstration and teaching. Is it too much? In addition, the nehe tutorial contains the relevant sections on loading graphics. It is a bit out of date to use the Glaux library, which is no longer recommended. I don't want to use this library, the best way is to understand the format of the bitmap file in bytes, read the relevant data directly, and then load it into its own structure. This can be used as a full cross-platform (irr
OpenGL usage in MFC (2) -- derived OpenGL class, mfcopengl Sometimes OpenGL needs to be configured every time, which is a little troublesome. You can directly derive an OpenGL Class Based on CWND and use it directly when necessary. The following is an example of this class, which deletes some specific items of my proje

OpenGL is an open source graphics library that can develop two-dimensional graphics software or three-dimensional graphics software. Many well-known applications have been developed based on OpenGL, such as the famous Artoolkit and Unity3d.Glut is the OpenGL Application Toolkit, known in English as OpenGL Utility Toolk

Multiple sampling in OpenGL and multiple sampling in OpenGLMultiple sampling in OpenGLOne of the biggest advantages of anti-sawtooth processing is that it can make the edge of the polygon smoother and make the rendering effect more realistic and natural. Point-and-line anti-sawtooth processing is widely supported, but unfortunately, the smooth processing of polygon is not implemented on all platforms. In addition, even when GL_POLYGON_SMOOTH can be us
have the "WGL" prefix affixed to them. This also assumes you know how to handle the Win32 API at some basic level of competence. you shoshould know what a window handle (hwnd) and a device context (DC) are, as well as how to create them. this is not a tutorial on how to create a window.Simple context Creation This section covers the basics of context creation.The window itself When you create your hwnd, you need to make sure that it has the cs_owndc
To use OpenGL ES to draw images in Android applications, you must create a view as a container. The more direct method is to derive an implementation class from GLSurfaceView and GLSurfaceView. Renderer. GLSurfaceView is a container drawn using OpenGL. GLSurfaceView. Renderer is used to control the drawing action. For more information about these classes, see the OpenGL
Almost all OpenGL applications aim to draw color images in the screen window, so Color plays an important role in OpenGL programming. The color here is different from the color concept in the painting. It belongs to the RGB color space and is only displayed on the monitor screen. In addition, the screen window coordinates are measured in pixels. Therefore, each pixel in a graph has its own color. This color

The confirmation method is as follows: Search for the following two files in the system directory (c: \ windows \ system32 by default for WINXP: Opengl32.dll and glu32.dll, if any, indicate that your video card has implemented the OpenGL interface
OpenGL vertex array, opengl Vertex In OpenGL, if you want to draw elements, the following operations are generally used: glBegin(GL_LINES); glVertex3f(0.0f, 0.0f, 0.0f); glVertex3f(1.0f, 0.0f, 0.0f);glEnd(); However, if the number of vertices is too large, This method requires frequent function calls, which is too inefficient. This requires the use of verte
Chapter 2 of OpenGl learning and Chapter 2 of opengl After openGl is basically drawn, it's time to move from a plane to a three-dimensional one. Now, to draw a Golden Triangle, the main problem is the fixed-point array, GL10.GL _ TRIANGLES, GL_TRIANGLES-this parameter means OpenGL uses three vertices to form a graph. T
There is a huge opportunity to migrate games and other applications that use a large number of 3D graphics from OpenGL to Google Android devices, including devices built on Intel's atom micro-architecture, because OpenGL-based games, game engines, and other traditional software are easy to obtain, OpenGL is easy to transplant, and Android can provide
