NAME
glRect - draw a rectangle C SPECIFICATION
void 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); PARAMETERS
x1, y1 Specify one vertex of a rectangle. x2, y2 Specify the opposite vertex of the rectangle. C SPECIFICATION
void 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); PARAMETERS
v1 Specifies a pointer to one vertex of a rectangle. v2 Specifies a pointer to the opposite vertex of the rectangle. DESCRIPTION
glRect 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. ERRORS
GL_INVALID_OPERATION is generated if glRect is executed between the execution of glBegin() and the corresponding execution of glEnd(). SEE ALSO
