Point Clouds

What would we do without point clouds? You can load one as simple as:

Builders

c++ PointCloud::Add(const vecs& X,scalar radius = -1);

const vecs& X std::vector<Eigen::Vector3d>
float radius point cloud radius (not relative), if not set then polyscope default radius is used. It can also be the name of a parameter or a snippet variable, to tune it live.

c++ PointCloud::Add(const std::string& file,scalar radius = -1);

const std::string& file a .ply or .obj file, only its vertices are read

Single Point

A single point, with more features, can be added using

c++ Point::Add(const vec& x,scalar radius = -1);

c++ Point::Add(const DynamicParam& x,scalar radius = -1);

DynamicParam = std::function<vec(TimeObject)> the point follows a time-dependent position (wrapper for its updater)

VectorFieldQuantity Point->addVector(const vec& v)

attaches a vector to the point, see polyscope quantities

Deck format

- cloud: scan.ply       # a .ply or .obj file, relative to the data path
  radius: scan_radius   # a number, or a name to tune it live
  normalize: true       # rescale the cloud to fit the scene
  color: [0.2, 0.4, 0.8]

It also takes the transform: of every scene item.
