class Transform from Vrml
---Purpose: defines a Transform of VRML specifying transform
--- properties.
-- This node defines a geometric 3D transformation consisting of (in order)
-- a (possibly) non-uniform scale about an arbitrary point, a rotation about
-- an arbitrary point and axis and translation.
-- By default :
-- myTranslation (0,0,0)
-- myRotation (0,0,1,0)
-- myScaleFactor (1,1,1)
-- myScaleOrientation (0,0,1,0)
-- myCenter (0,0,0)
uses
Vec from gp,
SFRotation from Vrml
is
Create returns Transform from Vrml;
Create ( aTranslation : Vec from gp;
aRotation : SFRotation from Vrml;
aScaleFactor : Vec from gp;
aScaleOrientation : SFRotation from Vrml;
aCenter : Vec from gp )
returns Transform from Vrml;
SetTranslation ( me : in out; aTranslation : Vec from gp );
Translation ( me ) returns Vec from gp;
SetRotation ( me : in out; aRotation : SFRotation from Vrml );
Rotation ( me ) returns SFRotation from Vrml;
SetScaleFactor ( me : in out; aScaleFactor : Vec from gp );
ScaleFactor ( me ) returns Vec from gp;
SetScaleOrientation ( me : in out; aScaleOrientation : SFRotation from Vrml );
ScaleOrientation ( me ) returns SFRotation from Vrml;
SetCenter ( me : in out; aCenter : Vec from gp );
Center ( me ) returns Vec from gp;
Print ( me; anOStream: in out OStream from Standard) returns OStream from Standard;
---C++: return &
fields
myTranslation : Vec from gp; -- Translation vector
myRotation : SFRotation from Vrml; -- Rotation
myScaleFactor : Vec from gp; -- Scale factors
myScaleOrientation : SFRotation from Vrml; -- Defines rotational space for scale
myCenter : Vec from gp; -- Center point for scale and rotate
end Transform;
