| Constructor Summary | |
| public | PickConeSegment()
Constructs an empty PickConeSegment.
The origin and end point of the cone are
initialized to (0,0,0). | | public | PickConeSegment(Point3d origin, Point3d end, double spreadAngle)
Constructs a finite cone pick shape from the specified
parameters. |
| Method Summary | |
| public void | getEnd(Point3d end)
Gets the end point of this PickConeSegment. | | final boolean | intersect(Bounds bounds, Point4d pickPos)
Return true if shape intersect with bounds.
The point of intersection is stored in pickPos.
Parameters:
bounds - the bounds object to check
Parameters:
pickPos - the location of the point of intersection (not used formethod. | | public void | set(Point3d origin, Point3d end, double spreadAngle)
Sets the parameters of this PickCone to the specified values. | | PickShape | transform(Transform3D t3d)
|
| PickConeSegment | | public PickConeSegment()(Code) | | Constructs an empty PickConeSegment.
The origin and end point of the cone are
initialized to (0,0,0). The spread angle is initialized
to PI/64 radians.
|
| PickConeSegment | | public PickConeSegment(Point3d origin, Point3d end, double spreadAngle)(Code) | | Constructs a finite cone pick shape from the specified
parameters.
Parameters:
origin - the origin of the cone
Parameters:
end - the end of the cone along the direction vector
Parameters:
spreadAngle - the spread angle of the cone in radians |
| getEnd | | public void getEnd(Point3d end)(Code) | | Gets the end point of this PickConeSegment.
Parameters:
end - the Point3d object into which the end pointwill be copied. |
| intersect | | final boolean intersect(Bounds bounds, Point4d pickPos)(Code) | | Return true if shape intersect with bounds.
The point of intersection is stored in pickPos.
Parameters:
bounds - the bounds object to check
Parameters:
pickPos - the location of the point of intersection (not used formethod. Provided for compatibility). |
| set | | public void set(Point3d origin, Point3d end, double spreadAngle)(Code) | | Sets the parameters of this PickCone to the specified values.
Parameters:
origin - the origin of the cone
Parameters:
end - the end of the cone
Parameters:
spreadAngle - the spread angle of the cone in radians |
