Specify the library handle. See "Library handle" for details.

Pointer to the ODB3DCD structure for the data of the 3-dimensional coordinate conversion.

typedef struct odb3dcd {
    short   mode;         /* 3-D coordinate conversion mode  */

} ODB3DCD ;

mode

Mode of the 3-dimensional coordinate conversion is set.

0	:	cancel mode
1	:	conversion mode

* In case of '0', the data except 'mode' is invalid.

dno

Number of 3-D coordinate conversion is set. Valid number is 1 or 2.

cd_axes

Axis number of 3-D coordinate conversion is set.

(0,..,MAX_AXIS-1) MAX_AXIS:max.controlled axes

cd_axes[0]	:	1st axis number
cd_axes[1]	:	2nd axis number
cd_axes[2]	:	3rd axis number

center

Absolute position of center of rotation is set.

center[0][0] to center[0][2]	:	1st time
center[1][0] to center[1][2]	:	2nd time

In case of dno=1, center[1][0],..,center[1][2] are not used.

direct

Direction of center is set.

direct[0][0] to direct[0][2]	:	1st time
direct[1][0] to direct[1][2]	:	2nd time

In case of nDno=1, lDirect(1,0),..,lDirect(1,2) are not used.

angle

Rotation angle of coordinate rotation is set.

angle[0]	:	1st time
angle[1]	:	2nd time

In case of dno=1, angle[1] is not used.
