obj2vtk: obj2vtk

In marta-vidalgarcia/mesh_process: An R tool for batch-processing of meshes and landmark files for shape analyses

obj2vtk

Description

Batch-converts OBJ mesh files into VTK mesh files

Usage

obj2vtk(files = NULL, ID = NULL, vtk_path = NULL, print.progress = TRUE)

Arguments

files	Optional parameter indicating where to save the VTK files. The default is the current directory.
ID	optional vector with IDs used for saving the VTK meshes. Default is the same name as the OBJ meshes
print.progress	optional parameter indicating whether to print the progress

Details

Takes a a list of OBJ meshes and transforms those files into VTK. For more information check the R package _freesurferformats_ (Schäfer, 2020)

Value

This function returns a table with the meshes information (name, number of faces and vertices) and the volume for each surface mesh.
