Detailed Description

Use to draw in a 3d or a 2d view.

• The 3d methods draw in the 3d system, in a 2d view the drawing is projected on X,Y.
• The 2d methods draw in the projection plane.
• To draw in screen coordinates the length must be divided by the zoom.

DrawTo() [1/2]

void Draw_Display::DrawTo

(

const gp_Pnt &

pt

)

DrawTo() [2/2]

void Draw_Display::DrawTo

(

const gp_Pnt2d &

pt

)

Flush()

void Draw_Display::Flush

(

)

const

HasPicked()

Standard_Boolean Draw_Display::HasPicked

(

)

const

Returs True if the last drawing operations generated a pick hit. When HasPicked is True the Drawing should be resumed.

This function is used to shorten the drawing when picking and to save the picked sub-parts.

void Draw_Display::MoveTo

(

const gp_Pnt2d &

pt

)

gp_Pnt2d Draw_Display::Project

(

const gp_Pnt &

pt

)

const

Returns the 2D projection of a 3D point.

Project() [2/2]

void Draw_Display::Project	(	const gp_Pnt &	pt,
		gp_Pnt2d &	pt2d
	)		const

Returns the 2D projection of a 3D point.

SetColor()

void Draw_Display::SetColor

(

const Draw_Color &

col

)

const

Following drawings will use this color.

SetMode()

void Draw_Display::SetMode

(

const Standard_Integer

M

)

const

Set the drawing mode, 3 = copy, 6 = xor.

ViewId()

Standard_Integer Draw_Display::ViewId

(

)

const

Returns the identifier of the view where the display is drawing.

Zoom()

Standard_Real Draw_Display::Zoom

(

)

const

Returns the current Zoom value.
