Point3d Object

Purpose:

returns a new Point3d object.

Syntax:

Create a new 3D point object at 0,0,0

p1 = point3d

 

Create at new 3D point object at given x,y

p2 = point2d(23.2 , 45.3 , 44)

 

Create a new 3D point array object of given size

pa = point3d(givensize)

 

After a point object or point object array has been created, the following methods can be used

x
y
z

After a  point object array has been created, the following methods can be used

id
xspan
yspan
zspan
xl
yl
zl
xh
yh
zh

After a  point object array has been created by using GPS methods, the following methods can also be used

time

Comments:

xl,yl and zl are the minimum x,y,z values of an array of points

xh,yh and zh are the maximu x,y,z values of an array of points

xspan,yspan and zspan are the difference

you can compute either span by

myxspan = pt.xh - pt.xl
