Name glAccum — operate on the accumulation buffer C Specification void glAccum(GLenum op, GLfloat value); Parameters op Specifies the accumulation buffer operation. Symbolic constants GL_ACCUM, GL_LOAD, GL_ADD, GL_MULT, and GL_RETURN are accepted. value Specifies a floating-point value used in the accumulation buffer operation. op determines how value is used. Description The accumulation buffer is an extended-range color buffer. Images are not rendered into it. Rather, images rendered into one of the color buffers are added to the contents of the accumulation buffer after rendering. Effects such as antialiasing (of points, lines, and polygons), motion blur, and depth of field can be created by accumulating images generated with different transformation matrices. Each pixel in the accumulation buffer consists of red, green, blue, and alpha values. The number of bits per component in the accumulation buffer depends on the implementation. You can examine this number by calling glGetIntegerv four times, with arguments GL_ACCUM_RED_BITS, GL_ACCUM_GREEN_BITS, GL_ACCUM_BLUE_BITS, and GL_ACCUM_ALPHA_BITS. Regardless of the number of bits per component, the range of values stored by each component is -1 1 . The accumulation buffer pixels are mapped one-to-one with frame buffer pixels. glAccum operates on the accumulation buffer. The first argument, op, is a symbolic constant that selects an accumulation buffer operation. The second argument, value, is a floating-point value to be used in that operation. Five operations are specified: GL_ACCUM, GL_LOAD, GL_ADD, GL_MULT, and GL_RETURN. All accumulation buffer operations are limited to the area of the current scissor box and applied identically to the red, green, blue, and alpha components of each pixel. If a glAccum operation results in a value outside the range -1 1 , the contents of an accumulation buffer pixel component are undefined. The operations are as follows: GL_ACCUM Obtains R, G, B, and A values from the buffer currently selected for reading (see glReadBuffer). Each component value is divided by 2 n - 1 , where n is the number of bits allocated to each color component in the currently selected buffer. The result is a floating-point value in the range 0 1 , which is multiplied by value and added to the corresponding pixel component in the accumulation buffer, thereby updating the accumulation buffer. GL_LOAD Similar to GL_ACCUM, except that the current value in the accumulation buffer is not used in the calculation of the new value. That is, the R, G, B, and A values from the currently selected buffer are divided by 2 n - 1 , multiplied by value, and then stored in the corresponding accumulation buffer cell, overwriting the current value. GL_ADD Adds value to each R, G, B, and A in the accumulation buffer. GL_MULT Multiplies each R, G, B, and A in the accumulation buffer by value and returns the scaled component to its corresponding accumulation buffer location. GL_RETURN Transfers accumulation buffer values to the color buffer or buffers currently selected for writing. Each R, G, B, and A component is multiplied by value, then multiplied by 2 n - 1 , clamped to the range 0 2 n - 1 , and stored in the corresponding display buffer cell. The only fragment operations that are applied to this transfer are pixel ownership, scissor, dithering, and color writemasks. To clear the accumulation buffer, call glClearAccum with R, G, B, and A values to set it to, then call glClear with the accumulation buffer enabled. Notes Only pixels within the current scissor box are updated by a glAccum operation. Errors GL_INVALID_ENUM is generated if op is not an accepted value. GL_INVALID_OPERATION is generated if there is no accumulation buffer. GL_INVALID_OPERATION is generated if glAccum is executed between the execution of glBegin and the corresponding execution of glEnd.

经典C程序100例如 题目：有1、2、3、4个数字，能组成多少个互不相同且无重复数字的三位数？都是多少？ 程序分析：可填在百位、十位、个位的数字都是1、2、3、4。组成所有的排列后再去掉不满足条件的排列。 程序源代码： main() { int i,j,k; printf("\n"); for(i=1;i<5;i++) /*以下为三重循环*/ 　for(j=1;j<5;j++)　 　　for (k=1;k<5;k++) 　　　{ 　　　　if (i!=k&&i!=j&&j!=k) /*确保i、j、k三位互不相同*/ 　　　　printf("%d,%d,%d\n",i,j,k); 　　　} }
