Fast access to billions of points in AutoCAD: PointCloud supports the visualisation and analysis of millions of 3D points within AutoCAD. When used within AutoCAD 2011, this is expanded up to 2 Billion points with the AutoCAD PCG format.
As the use of 3D Laser Scanners for recording industrial structures, historic buildings and sculptures increase, there is a need to be able to combine the resultant point cloud with other information such as photographs and vector data to produce complete records and possibly CAD drawings.
Running within the latest versions of AutoCAD, PointCloud reads most common data formats (see page 2). The Free Edition for AutoCAD 2011 imports these formats to AutoCAD PCG allowing any AutoCAD user to view their data within AutoCAD.
PointCloud and AutoCAD manage the number of points displayed on the screen to ensure optiimum display and making it easier for the operator to work with the cloud.
The number of displayed points is reduced during pan and orbit commands to ensure a swift transition between views.
PointCloud includes a “section manager” enabling the operator to divide the cloud into manageable portions for processing or visualisation. Single or multiple slices may be created with ease. Complex polygons may also be defined.
With oriented images loaded, the operator may use high resolution imagery to locate and trace details whilst PointCloud provides the full 3D location from the cloud data.
The native file format of PointCloud is the PTC file. Alternatively the software may use the AutoCAD PCG format allow- ing much larger clouds to be used.
