Segment
Summary
Stores a set of double values that represents a line segment.
Fields
| X1 | The X coordinate of the Start Point of the segment |
| X2 | The X coordinate of the End Point of the segment |
| Y1 | The Y coordinate of the Start Point of the segment |
| Y2 | The Y coordinate of the End Point of the segment |
| Z1 | The Z coordinate of the Start Point of the segment |
| Z2 | The Z coordinate of the End Point of the segment |
Methods
| ClosestPointTo | Returns a Point representing the closest point. |
| Constructor | This function has 6 overloads. |
| Crosses | Checks to see if two segments cross. This will not return true if the endpoints touch, or the lines are identical. Specifically the middle portions of the lines have to contact each other. |
| DistanceTo | This function has 3 overloads. |
| IntersectsWith | This function has 3 overloads. |
| IsCompletelyWithin | Returns true if the entire segment is within the polygon, without touching or crossing any of the edges. |
| IsIdenticalTo | Checks the points of the segemnts to see if they are the same, but is unconcerned with direction. |
| IsParallelTo | Returns true if the line segments are parallel |
| IsPerpendicularTo | Returns true if the line segments are perpendicular |
| IsWithinADistanceOf | This function has 2 overloads. |
| LocationByX | Given a segment, we try fix the value of one coordinate to solve for the other two. |
| LocationByY | Given a segment, we try fix the value of one coordinate to solve for the other two. |
| LocationByZ | Given a segment, we try fix the value of one coordinate to solve for the other two. |
| Touches | Checks to see if two segments touch. This is true if a vertex from one segment intersects with the other segment. Does not return true if only the line areas touch one another. |
| ToVector | Creates a new vector from this segment where the StartPoint becomes the beginning of the vector and the end point is the tip of the vector. |
