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