Hello,
Perhaps they use rotation on the objects, and not on the view ???

About V3d_View
We need for an operation the 4x4 Matrix of a V3d_View. In the CDL's I found this way:
TColStd_Array2OfReal array( 0, 3, 0, 3 );
Handle(Visual3d_View) hVisual3dView;
hVisual3dView = myView->View();
array = hVisual3dView->Transform();
But it delivers only: 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 all the time? Is it a bug, or is there another way to get the view transformation as a 4x4 matrix??
Thanks in advance
Jürgen

Hello Stephane,
In the documentation, I also see a way to get a matrix by projecting coordinates :
Visual3d_View::Projects
void Projects( const Standard_Real AX, const Standard_Real AY, const Standard_Real AZ, Standard_Real& APX,Standard_Real& APY, Standard_Real& APZ) const ;
Purpose
Returns the coordinates of the projection of the 3d coordinates AX, AY, AZ.
Hope this helps
