Compute Distance from a Point to a Line Segment
Usage
dis_point_to_edge(point, edge_start, edge_end)
Arguments
- point
A numeric vector representing a point.
- edge_start
A numeric vector representing the start of the edge.
- edge_end
A numeric vector representing the end of the edge.
Value
A numeric vector of length 2: the shortest distance and the scalar projection (t in [0,1]).
Details
Calculates the shortest distance from a point to a line segment in 2D or 3D space,
and returns the scalar projection position along the segment.
Examples
d <- dis_point_to_edge(c(0, 0), c(1, 0), c(1, 1))
print(d) # Expect ~1.0 distance to the vertical segment
#> [1] 1 0
