introduces a line l passing through the points
and . Line l is directed from
to .
| |
| |
introduces a line l passing through point
with direction .
| |
| |
returns the line supporting the segment , oriented
from source to target.
| |
| |
returns the line supporting the ray , with the same
orientation.
|
|
| Test for equality: two lines are equal, iff they have a non empty intersection and the same direction. |
|
| Test for inequality. |
|
| |
returns the orthogonal projection of on l. | ||
|
| returns an arbitrary point on l. It holds point(i) == point(j), iff i==j. |
|
| returns true if line l is degenerated to a point. |
|
|
|
| |
returns the plane perpendicular to l passing through . | ||
|
| returns the line with opposite direction. |
| ||
| returns the direction of l. | |
|
| |
returns the line obtained by applying on a point on l and the direction of l. |
