projRead: Project points onto the closest point on a mesh

Description

project points onto a given surface and return projected points and normals.

Usage

projRead(lm, mesh, readnormals = TRUE, smooth = FALSE, sign = TRUE, ...)

Arguments

lm

m x 3 matrix containing 3D coordinates.

mesh

character: specify path to mesh file.

readnormals

logical: return normals of projected points.

smooth

logical: rerturn smoothed normals.

sign

logical: request signed distances.

...

additional arguments currently not used.

Value

• if readnormals = FALSE, a m x 3 matrix containing projected points is returned, otherwise a list, where
• vb
  3 x m matrix containing projected points
• normals
  3 x m matrix containing normals
• quality
  vector containing distances
