Returns |
rotate
( xAngle, yAngle, ZAngle )
|
Applies a rotation transformation after the current transformation: model.transform.identity()
model.transform.translate(100,0,0)
model.transform.rotate(0,0,90)
After this series of transformations, performed in this order, the model's local origin will be at (0,100,0) , assuming the model's parent is the world. |
Nothing |
preRotate( xAngle, yAngle, ZAngle )
|
Applies a rotation transformation before the current transformation: model.transform.identity()model.transform.translate(100,0,0)model.transform.preRotate(0,0,90)
After this series of transformations, performed in this order, the model's local origin will be at (100,0,0) , assuming the model's parent is the world. |
Nothing |
rotate( point,vector, angle )
|
Similar to transform.rotate( xAngle , yAngle , zAngle ) , except that the arguments are two vectors specifying an axis of rotation as a point and a vector, plus an angle specifying the clockwise rotation around that axis: model.transform.identity()model.transform.translate(-50,0,0)model.transform.rotate(vector(100,0,0) vector(0,1,0))
After this series of transformations, performed in this order, the model's local origin will be at (250,0,0) , assuming the model's parent is the world. |
Nothing |
preRotate( point,vector, angle )
|
Similar to transform.preRotate( xAngle, yAngle, zAngle ) , except that the arguments are two vectors specifying an axis of rotation as a point and a vector, plus an angle specifying the clockwise rotation around that axis. model.transform.identity()model.transform.translate(-50,0,0)model.transform.preRotate(vector(100,0,0) vector(0,1,0))
After this series of transformations, performed in this order, the model's local origin will be at (150,0,0) , assuming the model's parent is the world. |
Nothing |
translate( xIncrement,yIncrement,zIncrement )
|
Translates the position of the transform relative to the transform's current orientation: model.transform.identity()model.transform.rotate(0,90,0)model.transform.translate(100,0,0)
After this series of transformations, performed in this order, the model's local origin will be at (100,0,0) , assuming the model's parent is the world. |
Nothing |
preTranslate( xIncrement,yIncrement,
zIncrement )
|
Translates the position of the transform before the current transformation: model.transform.identity()model.transform.rotate(0,90,0)model.transform.translate(100,0,0)
After this series of transformations, performed in this order, the model's local origin will be at (0,0,100) , assuming the model's parent is the world. |
Nothing |
multiply( transform2 )
|
Alters the original transform by applying the positional/rotational/scaling effects of transform2 to the original transform. If transform2 describes a rotation of 90° around the X axis and this transform describes a translation of 100 units in the Y axis, transform.multiply( transform2 ) alters this transform so that it describes a translation followed by a rotation. |
Nothing |
preMultiply( transform2 )
|
Alters the original transform by preapplying the positional/rotational/scaling effects of transform2 to the original transform. If transform2 describes a rotation of 90° around the X axis and this transform describes a translation of 100 units in the Y axis, transform.preMultiply( transform2 ) alters this transform so that it describes a rotation followed by a translation. |
Nothing |
interpolate
(oTransform2,fPercentage)
|
Returns a new transform by interpolating from the original transform to transform2 by fPercentage . The value of fPercentage should be between 0 and 100. |
A new transform object |
interpolateTo(oTransform2,fPercentage)
|
Modifies the existing transform by fPercentage . The value of fPercentage should be between 0 and 100. |
Nothing |
duplicate()
|
Returns a new transform that is a copy of the original transform. |
A new transform object |
identity
|
Resets the transform to an identity transform: position: 0,0,0 rotation: 0,00 scale: 1,1,1 |
Nothing |
invert()
|
Turns the transform into the inverse of its previous position and rotation. If you multiply a vector by a transform, the rotational and positional changes described by the transform are applied to the vector. Inverting the transform and multiplying the vector again restores the vector to its original. |
Nothing |
inverse()
|
Same as invert() except that the original transform is unaffected. |
A new transform object |
