Create a point cloud object — px

Base constructor for a platform-agnostic point cloud. Use px_aerial, px_terrestrial, or px_uav for platform-specific subtypes with smart defaults.

Usage

px_cloud(
  xyz,
  intensity = NULL,
  classification = NULL,
  rgb = NULL,
  normals = NULL,
  return_number = NULL,
  number_of_returns = NULL,
  metadata = list()
)

Arguments

xyz: Numeric matrix with 3 columns (x, y, z).
intensity: Numeric vector of intensity values, or NULL.
classification: Integer vector of ASPRS classification codes, or NULL.
rgb: Integer matrix with 3 columns (R, G, B), or NULL.
normals: Numeric matrix with 3 columns (nx, ny, nz), or NULL.
return_number: Integer vector of return numbers, or NULL.
number_of_returns: Integer vector of total returns, or NULL.
metadata: Named list of acquisition metadata.

Value

An object of class px_cloud.

Examples

xyz <- matrix(rnorm(300), ncol = 3)
cloud <- px_cloud(xyz)
print(cloud)
