	Sets up polygon offsets for this object. <br> It modifies all existing presentations of <anObj> (if any), <br> so it is reasonable to call this method after <anObj> has been displayed. <br> Otherwise, Compute() method should pass Graphic3d_AspectFillArea3d <br> aspect from <myDrawer> to Graphic3d_Group to make polygon offsets work. <br> <aMode> parameter can contain various combinations of Aspect_PolygonOffsetMode enumeration elements (Aspect_POM_None means that polygon offsets are not changed). If <aMode> is different from Aspect_POM_Off and Aspect_POM_None, then <aFactor> and <aUnits> arguments are used by graphic renderer to calculate a depth offset value: offset = <aFactor> * m + <aUnits> * r, where m - maximum depth slope for the polygon currently being displayed, r - minimum window coordinates depth resolution (implementation-specific). Deafult settings for OCC 3D viewer: mode = Aspect_POM_Fill, factor = 1., units = 0. Negative offset values move polygons closer to the viewport, while positive values shift polygons away. Consult OpenGL reference for details (glPolygonOffset function description). NOTE: This method has a side effect - it creates own shading aspect if not yet created, so it is better to set up object material, color, etc. first. More...

Detailed Description

Diameter dimension. Can be constructued:

On generic circle.
On generic circle with user-defined anchor point on that circle (dimension plane is oriented to follow the anchor point).
On generic circle in the specified plane.
On generic shape containing geometry that can be measured by diameter dimension: circle wire, circular face, etc. The anchor point is the location of the left attachement point of dimension on the circle. The anchor point computation is processed after dimension plane setting so that positive flyout direction stands with normal of the circle and the normal of the plane. If the plane is user-defined the anchor point was computed as intersection of the plane and the basis circle. Among two intersection points the one is selected so that positive flyout direction vector and the circle normal on the one side form the circle plane. (corner between positive flyout directio nand the circle normal is acute.) If the plane is computed automatically (by default it is the circle plane), the anchor point is the zero parameter point of the circle.

The dimension is considered as invalid if the user-defined plane does not include th enachor point and th ecircle center, if the diameter of the circle is less than Precision::Confusion(). In case if the dimension is built on the arbitrary shape, it can be considered as invalid if the shape does not contain circle geometry.

protectedvirtual

Checks if the center of the circle is on the plane.

Reimplemented from AIS_Dimension.

const gp_Circ& AIS_DiameterDimension::Circle ( ) const

Reimplemented from PrsMgr_PresentableObject.

virtual void AIS_DiameterDimension::ComputeAnchorPoint ( )

protectedvirtual

Override this method to change logic of anchor point computation. Computes anchor point. Its computation is based on the current dimension plane. Therfore, anchor point is an intersection of plane and circle. ATTENTION! 1) The plane should be set or computed before. 2) The plane should inclide th ecircle center to be valid.

	)

protectedvirtual

Override this method to compute selection primitives for flyout lines (if the dimension provides it). This callback is a only a part of base selection computation routine.

		gp_Pnt &	theSecondPnt
	)

protected

Compute points on the circle sides for the dimension plane. Program error exception is raised if the dimension plane "x" direction is orthogonal to plane (the "impossible" case). The passed dimension plane is the one specially computed to locate dimension presentation in circle.

void AIS_DiameterDimension::SetMeasuredGeometry ( const gp_Circ & theCircle )

Measure diameter of the circle. The actual dimension plane is used for determining anchor points on the circle to attach the dimension lines to. The dimension will become invalid if the diameter of the circle is less than Precision::Confusion().
