drawCircle()

static void View2DDraw::drawCircle ( ml::Vector2  c, double  r, int  n = 50, bool  fill = false  )

static

draws circle subdivided into n segments, using LINE_LOOP c and r are given in device coordinates

drawCross()

static void View2DDraw::drawCross ( ml::Vector2  c, double  r  )

static

draws cross centered at (cx,cy) with half width r, using LINES cx, cy, and r are given in device coordinates

drawEllipse()

static void View2DDraw::drawEllipse ( ml::Vector2  c, ml::Vector2  r1, ml::Vector2  r2, int  n = 50, bool  fill = false  )

static

draws ellipse with two half axes r1 and r2, subdivided into n segments, using LINE_LOOP cx, cy, and r are given in device coordinates

static

draws ellipse Band with two half axes r1 and r2, band is perpendicular to short axis and takes two arguments b1 and b2 (-1 <= b <= 1) as relative limits on short axis subdivided into n segments, using TRIANGLE_STRIP cx, cy, r and b are given in device coordinates

drawHalfEllipse()

static void View2DDraw::drawHalfEllipse ( ml::Vector2  c, ml::Vector2  r1, ml::Vector2  r2, double  b1, double  b2, int  n = 50, bool  fill = false, bool  stippled = false  )

static

Draws a part of a ellipse.

Parameters

c	center of the ellipse
r1	one of the two half axes of the ellipse
r2	one of the two half axes of the ellipse
b1	relative limit (between [-1,1]) on short axis to define one end of the part which has to be drawn
b2	see b1
n	defines in how much segments the ellipse should be devides
stippled	defines whether the part has to be drawn normally (false) or stippled (true)

drawRing()

static void View2DDraw::drawRing ( ml::Vector2  c, double  r1, double  r2, int  n = 50  )

static

draws ring or disk subdivided into n segments, using TRIANGLE_STRIP c, r1, and r2 are given in device coordinates, r1 may be zero
