mesh2mesh: projects the vertices of a mesh 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 (Euclidean distance or along vertex normals) on the target by for each vertex.

Usage

mesh2mesh(mesh1, tarmesh, clean = TRUE, cloud = FALSE, sign = FALSE)
ray2mesh(mesh1, tarmesh, tol = 1, angmax = NULL, clean = TRUE, 
    outname = NULL, readback = TRUE, inbound = FALSE, strict = FALSE, 
    ignore.stdout = 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).

clean

logical: request removing of dumpfiles.

cloud

logical: if TRUE and mesh1 is an external mesh file, face information will not be read from this file (saves time), as there is none present.

sign

logical: if TRUE, signed distances are returned.

tol

numeric: maximum distance to search along ray, closest Euclidean distance will be used, if tol is exceeded.

angmax

numeric: maximum angle (in radians) of normals of original and hit point are allowed to differ.

outname

character: set name of dumpfile used in the process.

readback

logical: whether the data is to be read into workspace.

inbound

inverse search direction along rays.

strict

logical: writes the value 1e12 into vertex quality if no face is hit by the ray.

ignore.stdout

suppress command line output.

mindist

search in both directions of the ray and use closest points.

Value

returns projected mesh

Details

needs trimesh_project and rayproject from trimesh-tools to be installed ( http://sourceforge.net/projects/morpho-rpackage/files/Auxiliaries/)
