A useful list of Building Information Model terms and acronyms is listed below. If you are doing architectural visualization you are sure to come across the need to understand and or even use BIM software, most notably Revit from Autodesk. At 3DAllusions Studio we offer price breaks for the use of Clients Revit models in assembling out scenes. In this way the Client and our studio capitalizes on the efforts already made as best we can to reduce redundancy and wasted efforts to provide the most economical solutions we possibly can.

Point Cloud is a set of vertices in a three-dimensional coordinate system. These vertices are usually defined by X, Y and Z coordinates, and typically are intended to be representative of the external surface of an object. Point clouds are most often created by 3D scanners.

The point cloud represents the set of points that the device has measured (as defined on Wikipedia)
