Vr Mapping




Getting Started With 3D ViewPoint (3DSC) - VrThree (VrLiDAR)



3D ViewPoint is a 3D stereo window. This window displays point and vector data contained by VrOne data files and is designed for the collection of vector data using LiDAR and (or) point clouds as reference. The 3D ViewPoint window is designed for point and vector data without any imagery. Although 3D ViewPoint can be started from VrOne or VrTwo it is recommended that it be started from VrOne.


All vector and point data is viewed in true 3D stereo.
Data may be observed from any viewpoint, origin and scale.
Vector data may be collected and edited using the standard Vr Mapping commands and applications including Function keys.
Two cursor modes include Cursor Draping and Free Motion.
Roaming is supported
On two-screen systems, the 2D VrOne window may be moved to the second screen (typically the right screen)



The hardware requirements for 3D ViewPoint are the same as those for VrTwo. At the present time several graphics cards have been tested, namely:


NVIDIA Quadro FX 3700
NVIDIA Quadro FX 3800
NVIDIA Quadro FX 4600
NVIDIA Quadro FX 4800
NVIDIA Quadro 4000
NVIDIA Quadro 5000
NVIDIA Quadro K5000


Most of the existing stereo graphics cards that are supported by VrTwo should be supported by ViewPoint but not all have been tested.

If running on 64-bit Windows 7, the amount of memory in the computer should be 8GB or greater for large data sets.

See Hardware for more information on hardware configurations.

Operating Systems

The 32-bit version of  VrOne with 3D ViewPoint will run in Windows 7 or Windows XP. The 64-bit version of VrOne with 3D ViewPoint will run in the 64-bit Windows 7. For larger data sets Windows 7 64-bit and VrOne 64-bit are recommended.

The recommended operating system for 3D ViewPoint is 64-bit Windows 7.

Getting Started

Translating LiDAR Data

3D Viewpoint requires VrOne files. This LiDAR data can be translated into existing VrOne files or new VrOne files can be created during the translation process.


Typically, LiDAR data is delivered in the LAS format and can be translated into a VrOne/VrTwo database file or files using the LAS In (LasIn) translator. LiDAR can be translated from the Vr database to LAS using the LAS Out (LasOut) translator.  Another supported format for the translation of LiDAR data into VrOne files is the points format.  The Points In (PoiIn) and Points Out (PoiOut) translators support this format.

More information on these input/output translators can be found at the following links:

Points In
Points Out

Starting 3D ViewPoint

VrPoints (LiDAR) data is stored in the VrOne/VrTwo database which is the same database used to store lines, symbols and text. Each VrPoint in the VrOne/VrTwo database contains XYZ coordinates and point attributes as defined by the ASPRS LAS format specification.  To start 3D ViewPoint the following steps may be used.

Start VrOne
Open VrOne file
Start 3D ViewPoint with the 3DSC command


When 3D ViewPoint is started, it will open a stereo window. The original VrOne 2D window will remain open. This 2D window may be placed on the second screen if available. It is recommended that the VrOne be started with a single 2D window and then ViewPoint be opened. Before closing VrOne, it is recommended to close ViewPoint using the ‘X’ button on the upper right corner of the window.


With two windows open, the cursor may be moved between the ViewPoint window and the VrOne 2D window.
