| SbLine Structure |
Directed line in 3D.
Represents a directed line in 3D. This is a basic Open Inventor datatype that is used for representing a 3D line. It is used as input and output by a variety of Open Inventor classes.

SyntaxThe SbLine type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SbLine |
Constructor. To struct a line from a position and direction, use SbLine(p0, p0 + dir) |
Methods| Name | Description | |
|---|---|---|
| Equals | (Inherited from ValueType.) |
| GetClosestPoint |
Returns the closest point on the line to the given point.
|
| GetClosestPoints |
Finds the two closest points between this line and line2, and loads them
into ptOnThis and ptOnLine2.
|
| GetDirection | Obsolete.
Use direction property instead.
|
| GetDirection(SbVec3f) |
Gets the direction of the line.
|
| GetHashCode | (Inherited from ValueType.) |
| GetPosition | Obsolete.
Use position property instead.
|
| GetPosition(SbVec3f) |
Gets the position of the line.
|
| GetType | (Inherited from Object.) |
| SetPosDir(SbVec3f, SbVec3f) |
Sets line using a position and a direction vector.
|
| SetPosDir(SbVec3f, SbVec3f) |
Sets line using a position and a direction vector.
|
| SetValue(SbVec3f, SbVec3f) |
Sets line to pass through points p0 and p1.
|
| SetValue(SbVec3f, SbVec3f) |
Sets line to pass through points p0 and p1.
|
| ToString |
Converts this SbLine structure to a human readable string.
(Overrides ValueTypeToString.) |
Properties| Name | Description | |
|---|---|---|
 | Direction |
Gets or sets a vector indicating the direction of line.
When setting the direction, the vector value is automatically normalized.
|
| Position |
Gets or sets a vector indicating indicating
the position of line origin point.
