Point-filter functions
DescriptionFunction
X component of a point; Y and Z components are set to 0.0xof(p1)
Y component of a point; X and Z components are set to 0.0yof(p1)
Z component of a point; X and Y components are set to 0.0zof(p1)
X component of a pointrxof(p1)
Y component of a pointryof(p1)
Z component of a pointrzof(p1)
The following example provides the Z component of a point expressed in
spherical coordinates:
zof([2<45<45])
The following example provides a point whose X and Y coordinate values are
taken from point a and the Z coordinate value from point b:
xyof(a)+zof(b)

Calculate a Point on a Line
The plt and pld functions return a point on a given line. You can specify the
location of the point on the line either by its distance from the first point or
parametrically by a t parameter.
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 location of the point on the line.
