CloudCompare is a 3D point cloud processing software (such as those obtained with a laser scanner).It can also handle triangular meshes and calibrated images. Originally created during a collaboration between Telecom ParisTech and the R&D division of EDF, the CloudCompare project began in 2003 with the PhD of Daniel Girardeau-Montaut on Change detection on 3D geometric data.

FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. [4] It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical ...
A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.
Interactive geometry software (IGS) or dynamic geometry environments (DGEs) are computer programs which allow one to create and then manipulate geometric constructions, primarily in plane geometry. In most IGS, one starts construction by putting a few points and using them to define new objects such as lines , circles or other points.
The projection function P takes as its input a camera vector (denoted camera) and another vector the position of a 3-D point in space (denoted xyz) and returns a 2D point that has been projected onto a plane in front of the camera (denoted XY). We can express this: XY = P(camera, xyz) An illustration of feature projection.
CloudCompare is an open source 3D point cloud editing and processing software. Cobalt is a parametric-based Computer-aided design (CAD) and 3D modeling software for both the Macintosh and Microsoft Windows. It integrates wireframe, freeform surfacing, feature-based solid modeling and photo-realistic rendering (see Ray tracing), and animation.
It is the reverse process of obtaining 2D images from 3D scenes. The essence of an image is a projection from a 3D scene onto a 2D plane, during which process the depth is lost. The 3D point corresponding to a specific image point is constrained to be on the line of sight.
Once common, isometric projection became less so with the advent of more powerful 3D graphics systems, and as video games began to focus more on action and individual characters. [7] However, video games utilizing isometric projection—especially computer role-playing games—have seen a resurgence in recent years within the indie gaming scene ...
