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

, the answer is: Create a cube... then it will crash. Assume that you have a certain degree of C \ c ++ programming basics, and then you are familiar with QT. If not, it is recommended to take the QT tutorial of bean, although it has not been updated for a long time.Iii. Preparations First of all, you should configure ubuntu. See my other article :. Create a famous workstation-configure Ubuntu Then install QT and creater, and enter the terminal: Sudo apt-Get install qtcreator QT-SDK Open create

# Include ThisCodeThe general explanation is as follows: 1. First, add the necessary header file glut. H is included to use the function library provided by OpenGL. 2. display is a callback function written by the Program , used for drawing in a window. After registering it with the help of the main function, each time the image in the window needs to

glsl generated by the CG compiler requires some adjustments to work on the ATI driver. Therefore, an extra conversion is required. Fortunately, these tasks can be completed automatically through the program, and the speed is very fast. For details, refer to klayge's oglshaderobject: converttoglsl. In fact, all shader of klayge only writes one copy (the syntax uses HLSL 11 ), different APIs can be automatically compiled into Native shader for use (com

. We only have one attribute, so the value is 0. If we have two attributes, A position and a normal direction. If they are all vectors in the 3-dimensional float format, this parameter must be set to (6*4) = 24 byte, And the last parameter is offset, if there are two attributes, this value is 0 for the first attribute, no offset, and 12 for the second attribute. glDrawArrays(GL_POINTS, 0, 1); Finally, we call the draw function, which is the starting p

scenario. The atmospheric effect (collectively referred to as "fog") is used to add a depth prompt (depth-cue) and an antialiased effect, perform flat-shading and smoth-shading respectively, and add shadow and texture effects to the scene) A 2D image can be projected onto a 3D object, followed by motion-blurred, angle conversion, depth of field effect (depth-of-field ).Effect. This is a specific example. We can summarize the main graphic operations of OpenG
