class MatrixTransform from Vrml
---Purpose: defines a MatrixTransform node of VRML specifying matrix and transform
-- properties.
-- This node defines 3D transformation with a 4 by 4 matrix.
-- By default :
-- a11=1 a12=0 a13=0 a14=0
-- a21=0 a22=1 a23=0 a24=0
-- a31=0 a32=0 a33=1 a34=0
-- a41=0 a42=0 a43=0 a44=1
-- It is written to the file in row-major order as 16 Real numbers
-- separated by whitespace. For example , matrix expressing a translation
-- of 7.3 units along the X axis is written as:
-- 1 0 0 0 0 1 0 0 0 0 1 0 7.3 0 0 1
uses
Trsf from gp
is
Create returns MatrixTransform from Vrml;
Create ( aMatrix : Trsf from gp )
returns MatrixTransform from Vrml;
SetMatrix ( me : in out; aMatrix : Trsf from gp );
Matrix ( me ) returns Trsf from gp;
Print ( me; anOStream: in out OStream from Standard) returns OStream from Standard;
---C++: return &
fields
myMatrix : Trsf from gp; -- Transformation matrix
end MatrixTransform;
