Description

This function adds a circular arc graphic to the specified 3D graphics list, allowing you to, for example, view the circular arc graphic on a 3D display.

You must specify the label of the 3D graphic, in the 3D graphics list, to use as the parent of the arc graphic. When the arc graphic is added to the 3D graphics list's tree structure, it is added as a child under the specified parent. If the 3D graphics list is empty, the arc graphic's parent must be the root node. The coordinates of the arc's vertices are expressed in the coordinate system of the arc graphic's parent.

The arc graphic has its own coordinate system that represents the arc's position and orientation with respect to its parent's coordinate system. The arc's coordinate system's origin is the arc's center, its X-axis is the vector directed from the arc's center to the arc's start point, and its Z-axis is the arc's normal vector. You can inquire the arc's start point and normal vector using M3dgraInquire() with M_START_POINT_... and M_NORMAL..., respectively.

To modify or inquire 3D graphics list settings, use M3dgraControl() or M3dgraInquire(), respectively.

Unlike most other functions that modify a MIL object, you can call this function concurrently from multiple threads on the same MIL 3D graphics list (List3dgraId) without using an M_MUTEX object, as long as all the other parameters of the concurrent calls do not also share data.

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see if there is complementary information.

Parameters

This function is not supported on the selected boards.

M_CENTER_AND_TWO_POINTS			Defines a circular arc graphic using a center and two end points. The result will be a circular arc, with a radius defined by the center and the first end point. The arc extends from the first end point to the point on the line that passes through the center and the second end point. Therefore, the second end point does not have to be a point on the arc. (summarize) Defines a circular arc graphic using a center and two end points. (more details...)
	X1		Specifies the X-coordinate of the arc's center.
	Y1		Specifies the Y-coordinate of the arc's center.
	Z1		Specifies the Z-coordinate of the arc's center.
	X2		Specifies the X-coordinate of the arc's first end point.
	Y2		Specifies the Y-coordinate of the arc's first end point.
	Z2		Specifies the Z-coordinate of the arc's first end point.
	X3		Specifies the X-coordinate of the arc's second end point.
	Y3		Specifies the Y-coordinate of the arc's second end point.

The result will be a circular arc that extends from the first end point, to the point on the line that passes through the center and the second end point. Therefore, the second end point does not have to be a point on the arc. (summarize) Defines a circular arc graphic using a center and two vectors. (more details...)
