)

Value

endocast mesh3d: mesh of the endocast

volume numeric: volume of the endocast expressed in cc

Arguments

mesh

mesh3d: 3D model of the skull

path_in

character: path of the skull where is stored

param1_endo

numeric: parameter for spherical flipping

npovs

numeric: number of Points of View used in the endocast construction

volume

logical: if TRUE the calculation of the volume (expressed in cc) through concave is returned

alpha_vol

numeric: alpha shape for volume calculation

nVoxels

numeric: number of voxels for estimation endocranial volume

decmesh

numeric: decmesh

alpha_ext

numeric: alpha shape for construction external cranial mesh

ncells

numeric: approximative number of cell for 3D grid construction

npovs_calse

numeric: number of Points of View for construction of skull shell

param1_calse

numeric: parameter for calse (construction shell)

param1_ast

numeric: parameter for ast3d (construction row endocast)

decendo

numeric: desired number of triangles (row endocast)

scalendo

numeric: scale factor row endocast (for definition of POVs)

alpha_end

numeric: alpha shape value for concave hull (row endocast)

mpovdist

numeric: mean value between POVs and mesh

plot

logical: if TRUE the endocast is plotted

colmesh

character: color of the mesh to be plotted

save

logical: if TRUE the mesh of the endocast is saved

outpath

character: path where save the endocast

num.cores

numeric: numbers of cores to be used in parallel elaboration
