GLRECT(3G) OpenGL Manual GLRECT(3G)NAMEglRect - draw a rectangleC SPECIFICATIONvoid glRectd(GLdouble x1, GLdouble y1, GLdouble x2, GLdouble y2); void glRectf(GLfloat x1, GLfloat y1, GLfloat x2, GLfloat y2); void glRecti(GLint x1, GLint y1, GLint x2, GLint y2); void glRects(GLshort x1, GLshort y1, GLshort x2, GLshort y2);PARAMETERSx1, y1 Specify one vertex of a rectangle. x2, y2 Specify the opposite vertex of the rectangle.C SPECIFICATIONvoid glRectdv(const GLdouble * v1, const GLdouble * v2); void glRectfv(const GLfloat * v1, const GLfloat * v2); void glRectiv(const GLint * v1, const GLint * v2); void glRectsv(const GLshort * v1, const GLshort * v2);PARAMETERSv1 Specifies a pointer to one vertex of a rectangle. v2 Specifies a pointer to the opposite vertex of the rectangle.DESCRIPTIONglRect supports efficient specification of rectangles as two corner points. Each rectangle command takes four arguments, organized either as two consecutive pairs of x y coordinates or as two pointers to arrays, each containing an x y pair. The resulting rectangle is defined in the z = 0 plane. glRect(x1, y1, x2, y2) is exactly equivalent to the following sequence: glBegin(GL_POLYGON); glVertex2(x1, y1); glVertex2(x2, y1); glVertex2(x2, y2); glVertex2(x1, y2); glEnd(); Note that if the second vertex is above and to the right of the first vertex, the rectangle is constructed with a counterclockwise winding.ERRORSGL_INVALID_OPERATION is generated if glRect is executed between the execution of glBegin() and the corresponding execution of glEnd().SEE ALSOglBegin(), glVertex()COPYRIGHTCopyright (C) 1991-2006 Silicon Graphics, Inc.
