union() 569
•
#world
applies the increments relative to the world coordinate system. If a model’s parent is
the world, than this is equivalent to using
#parent
.
•
nodeReference
allows you to specify a node to base your translation upon, the command
applies the translations relative to the coordinate system of the specified node.
Example
This example constructs a transform using the transform command, then it initializes the
transform’s position and orientation in space before assigning the transform to the model named
mars. Finally this example displays the resulting position of the model.
t =transform()
t.transform.identity()
t.transform.rotate(0, 90, 0)
t.transform.translate(100, 0, 0)
gbModel = member("scene").model("mars")
gbModel.transform = t
put gbModel.transform.position
-- vector(100.0000, 0.0000, 0.0000)
This Lingo moves the model Bip 20 units along the x axis of its parent node:
put member("Scene").model("Bip").position
-- vector( -38.5000, 21.2500, 2.0000)
member("Scene").model("Bip").translate(20, 10, -0.5)
put member("Scene").model("Bip").position
-- vector( -18.5000, 31.2500, 1.5000)

union()
Usage
rect( 1 ).union( rect ( 2 ))
union ( rect1 , rect2 )
Description
Function; returns the smallest rectangle that encloses two rectangles.
Parameters
rect2
Required. Specifies the second rectangle.
Example
This statement returns the rectangle that encloses the specified rectangles:
put union (rect (0, 0, 10, 10), rect (15, 15, 20, 20))
-- rect (0, 0, 20, 20)
or
put rect(0, 0, 10, 10).union(rect(15, 15, 20, 20))
--rect (0, 0, 20, 20)
