This paper deals with new aspects of 3Dvisualization Techniques as state-of-the-art tools for recording, documentation, interpretation etc..

To give an idea of the outstanding documentary value of 3D-images and of its broad range of applications, masterpieces for stereoviews and for forensic 3Dphotography are initially presented (see the authors`RecorDIM -website 3dsite.icomos.org).

Since these samples represent huge stereoviewcollections, this paper also deals with international 3D-image- archives.

First time gaining "3D-niche-photography" based on a telescope-rod-Lite-platform is introduced. In the following are highlighted advantages for the practical use of stereoviews, e. g.,, - the still underestimated effect of gaining a complete additional dimension and - advantages of 3D-visualization for the enhancement of spatial structures, as well as - pointing to the extremely high detail resolution and to - the probative force of forensic 3Dphotography.

Finally a new way to derive terrain-heights from image-parallax-values is shown for aerial photography and for SAR-imagery, as well as a completed list of virtual 3D-visualizationmethodology, including "Down-Under"and Felix- Solid-State type 3D-screens to replace the 2D-PC(- screen).
