Transform properties
Use these properties to work with transforms:
Property Access Description Default
position
Get and set Lingo vector object describing the position of
a transform with the value
vector( xOffset, yOffset,
zOffset ) . A model.transform position
represents the model’s position in relation to
its parent.
vector
(0,0,0)
scale
Get and set Lingo vector object describing the x, y, and z
scale of the transform with the vector value
vector( xScale, yScale, zScale )
.
Scaling is always applied model-relative.
vector
(1,1,1)
rotation
Get and set Lingo vector object describing the
xRotation
,
yRotation
,
and
zRotation
components of the transform
with the value
vector( xRotation ,
yRotation , zRotation )
, with the
rotation values defined in degrees.
This value can vary because of the
permissible types of transform operation. For
example,
translate
followed by
rotate
gives a different value than rotate followed
by
translate
, and the results can’t be
differentiated after the fact from the rotational
information alone.
The
rotate()
and
preRotate()
commands are the preferred way to modify a
transform’s orientation. Rotation is generally
relative to the object’s original orientation at
the start of the movie.
vector
(0,0,0)
axisAngle
Get and set A list including a vector and a floating-point
value that describes this transform’s rotation
as an axis/angle pair.
The vector represents the direction, and the
angle represents the rotation around the
vector.
[vector
(1.0000,
0.0000,
0.0000)
A]
x axis
Get and set A vector representing the transform’s
canonical x axis in transform space. Example:
transform.identity()
transform.rotate(0,90,0))
put transform.xaxis
--vector(0,0,-1)
Canonical means reduced to the simplest
possible mathematical expression.
vector
(1,0,0)
