Description
Returns TRUE if the 3D points are equal within the tolerance.
FUNCTION EqPt3D(
pt1 :VECTOR;
pt2 :VECTOR;
tolerance :REAL) : BOOLEAN;
def vs.EqPt3D(pt1, pt2, tolerance): return BOOLEAN
Parameters
pt1 VECTOR pt2 VECTOR tolerance REAL
Remarks
(_c_, 2022.01.22) :
- Python: contrary to most Pascal-derived vectorial routines, it accepts also bidimensional tuples or even a 2/3-dimensional mix
- Python and Pascal: Don't pass 0 to the tolerance, or the routine will always return false.
Example
Vectorscript
PROCEDURE Example; VAR v1, v2 : VECTOR; BEGIN v1.x := 12; v1.y := 1; v1.z := 999; v2.x := 12; v2.y := 1; v2.z := 999.01; Message(Concat( EqPt3D(v1, v2, 0.1) )); { returns true } Message(Concat( EqPt3D(v1, v2, 0.01) )); { returns false } Message(Concat( EqPt3D(v1, v2, 0) )); { always returns false! Don't use tolerance zero } END; Run(Example);
Python
v1 = (12, 1, 999) # also accepts bidimensional tuples v2 = (12, 1, 999) vs.Message( str(vs.EqPt3D(v1, v2, 0.01)) ) # returns true # example with faulty tolerance v1 = (12, 1, 999) v2 = (12, 1, 999) vs.Message( str(vs.EqPt3D(v1, v2, 0)) ) # always returns false! Don't use tolerance zero
