learn opengl

1. Configure the OpenGL environment to download glut (OpenGL utility Toolkit) https://www.opengl.org/resources/libraries/glut/to Local. After decompression there are two Lib files, two DLL files and one. h file.2. Glut.lib and Glut32.lib are copied to X:\Program Files (x86) \microsoft Visual Studio 12.0\vc\lib.3. Glut.dll and Glut32.dll copied to the C:\Windows\system32 folder (32-bit system) or? C:\WINDOWS

Write in frontThen the previous section, when the development environment was set up, of course, we wanted to write 3D applications right away. But we also need some patience, because OpenGL is a low-level API, so we have a little more basic knowledge, before we begin to draw 3D graphics, we will be familiar with the concepts and processes of modern OpenGL by drawing a triangular program. In this section yo

. Learn about 2D. Let's take a look at the 3D drawing method. 3D drawing SDK is very simple. It just introduces a general method, that is, inheriting a View, and then obtaining the Opengl handle in this View for drawing, it should be the same as 2D. The difference is that 2D APIs are used for drawing, and 3D is used for drawing. However, because 3D openGl | ES ha

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

Foreword OpenGL is a set of drawing function libraries developed by SGI. It is a set of C language functions for the development of 2D and 3D graphics applications. OpenGL makes it unnecessary for program developers to consider whether the underlying operations of various display cards are the same. The hardware is communicated by the OpenGL core. Therefore, as l

For more information, see http://www.cppblog.com/doing5552/archive/2009/01/08/71532.html. 1. Check whether the graphics card of the Local Machine supports OpenGL. 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

How does opengl display the texture-rich and opengl In the opengl Post Bar, someone turns up a previous help post: // According to the NeHe tutorial lesson6, we got a texture-based ry # include // Use auxDIBImageLoad to load the texture # include # Pragma comment (lib, "GLAUX. lib") # include GLuint texture [1]; AUX_RGBImageRec * LoadBMP (cha

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

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
