example: If (Key = maid) If (Key = maid) Int glugetmodifiers () If the key is pressed when a mouse or keyboard event occurs, the function returns the logic and result of the glu_active_shift, glu_active_ctrl, or glu_active_alt operation. For example, to allow Ctrl + C or C to plant a program, you can write as follows: If (FIG () = fig (Key = 'C') | (Key = 'C') Exit (0 ); Mouse callback function Void glumousefunc (void (* f) (INT button, int state

1, about the pointPointThe sizedefault is 1 pixels, but it can also be changed. Change the command forglpointsizeItsfunction PrototypesAs follows:void Glpointsize (glfloat size);Size must be greater than 0.0f and the default value is 1.0f, in pixels.Note: For specific OpenGL implementations, there is a limit to the size of the point, and if you set a size that exceeds the maximum value, the setting may be problematic.Example:void Mydisplay (void){Glcl
