CATAxisSystemAxisType (Enumeration)
enum CATAxisSystemAxisType {
catAxisSystemAxisSameDirection,
catAxisSystemAxisByCoordinates,
catAxisSystemAxisOppositeDirection
}
Specification of the axes of the coordinate system.
- Values:
-
- catAxisSystemAxisSameDirection
- = 0 Specifies that the axis direction is defined by a point, line, or plane.
If the axis is defined by a point, the axis has the direction of the vector
going from the origin of the coordinate system to the point.
If defined by a line, the axis has the same direction as the line.
If defined by a plane, the axis has the same direction as the normal vector of the plane.
- catAxisSystemAxisByCoordinates
- = 1 Specifies that the axis direction is defined by the three coordinates x,y,z of a vector.
- catAxisSystemAxisOppositeDirection
- = 2 Specifies that the axis direction is not specified or defined by a point, line, or plane.
If the axis is defined by a point, the axis has the direction of the vector
going from the point to the origin of the coordinate system.
If defined by a line, the axis has the opposite direction of the line.
If defined by a plane, the axis has the opposite direction of the normal vector of the plane.
