A utility function for drawing vector diagrams. Draws two line segments to indicate the angle between two vectors, typically used for indicating orthogonal vectors are at right angles in 2D and 3D diagrams.
Arguments
- p1
Starting point of first vector
- p2
End point of first vector, and also start of second vector
- p3
End point of second vector
- d
The distance from
p2
along each vector for drawing their corner- absolute
logical; if
TRUE
,d
is taken as an absolute distance along the vectors; otherwise it is calculated as a relative distance, i.e., a fraction of the length of the vectors. SeepointOnLine
for the precise definition.- ...
Details
In this implementation, the two vectors are specified by three points, p1
, p2
, p3
, meaning
a line from p1
to p2
, and another line from p2
to p3
.
