pld(p1,p2,dist)
Calculates a point on the line passing through points p1 and p2. The
parameter dist defines the distance of the point from the point p1.
plt(p1,p2,t)
Calculates a point on the line passing through points p1 and p2. The
parameter t defines the parametric position of the point on the line.
The following are examples of the parameter t:
If t=0 the point is p1
If t=0.5 the point is the midpoint between p1 and p2
If t=1 the point is p2
Rotate a Point About an Axis
The rot function rotates a point about an axis and returns the resulting point.
rot(p,AxP1,AxP2,ang)
Rotates point p through an angle ang about the axis passing through points
AxP1 and AxP2, as shown in the following example. The axis is oriented
from the first point to the second point.
ang
p
AxP1
AxP2
rot(p,origin,ang)
Rotates point p through angle ang about the Z axis passing through the
point origin, as shown in the following example:
