In Morpho: Calculations and Visualisations Related to Geometric Morphometrics

projects the vertices of a mesh along its normals onto the surface of another one.

Description

projects the vertices of a mesh onto the surface of another one by searching for the closest point along vertex normals on the target by for each vertex.

Usage

ray2mesh(mesh1, tarmesh, tol = 1e+12, inbound = FALSE, mindist = FALSE, ...)

Arguments

mesh1	mesh to project. Can be an object of class "mesh3d" or path to an external mesh file (ply, obj, stl).
tarmesh	mesh to project onto. Can be an object of class "mesh3d" or path to an external mesh file (ply, obj, stl).
tol	numeric: maximum distance to search along ray, closest Euclidean distance will be used, if tol is exceeded.
inbound	inverse search direction along rays.
mindist	search both ways (ray and -ray) and select closest point.
...	additional arguments not used at the moment.

Value

returns projected mesh with additional list entries:

quality	integer vector containing a value for each vertex of x: 1 indicates that a ray has intersected 'tarmesh' within the given threshold, while 0 means not
distance	numeric vector: distances to intersection
