Open3D (C++) calculates the surface area and volume of the point cloud model


Note : This algorithm is based on the triangulation model to calculate the point cloud volume and surface area.

In Open3D, the commonly used methods for point cloud construction models are:
8. 3D reconstruction

1. Function analysis

/// Function that computes the surface area of the mesh, i.e. the sum of
    /// the individual triangle surfaces.
    double GetSurfaceArea() const;
  • Computes the surface area of ​​the mesh, which is the sum of the surfaces of the individual triangles.
