OpenGL函数库(国外英文资料) 1. The OpenGL core library The core library contains 115 functions, and the prefix of the function name is gl. This function is used for regular, core graphics processing. This function is explained by the gl. DLL. Because many functions can receive several classes of different Numbers. According to type parameters, the derived functions are more than 300. Functions in the core library can be broken down into the following types of functions: (1) the function that draws the basic geometry. Such as glBegain (), glEnd (), glNormal * (), glVertex * (). (2) functions of matrix operation, geometric transformation and projection transformation. Such as matrix into the stack function glPushMatrix () function, matrix a stack glPopMatrix () function, load matrix glLoadMatrix glMultMatrix (), matrix multiplication function (), the current matrix function glMatrixMode glLoadIdentity () and matrix standardization function (), geometric transformation function glTranslate * (), () and glScale glRotate * * (), projection transformation function glOrtho (), glFrustum () and viewport transformation function glViewport () and so on. (3) functions of color, illumination, and texture. For example, set the color mode function glColor * (), glIndex * (), the function glLight (), glLightModel * (), and the set material effect function glMaterial (), etc. (4) shows a list of functions, mainly has created, end, to generate the display list, delete, and call the function of glNewList (), glEndList (), glGenLists (), glCallList () and glDeleteLists (). (5) texture mapping function, the main one dimensional texture function glTexImage1D glTexImage2D (), 2 d texture function (), set the texture parameters, the environment and function of the texture coordinates glTexParameter * * () (), glTexEnv and glTetCoord * (), etc. (6) special effects functions. The merge function glBlendFunc (), the reverse sample function glHint () and the atomization effect glFog * (). (7) grating an
