Import common mesh file formats.
Import common mesh file formats and store the results in an object of class "mesh3d" - momentarily only triangular meshes are supported.
vcgImport( file, updateNormals = TRUE, readcolor = FALSE, clean = TRUE, silent = FALSE )
file |
character: file to be read. |
updateNormals |
logical: if TRUE and the imported file contais faces, vertex normals will be (re)calculated. Otherwise, normals will be a matrix containing zeros. |
readcolor |
if TRUE, vertex colors and texture (face and vertex) coordinates will be processed - if available, otherwise all vertices will be colored white. |
clean |
if TRUE, duplicated and unreferenced vertices as well as duplicate faces are removed (be careful when importing point clouds). |
silent |
logical, if TRUE no console output is issued. |
Object of class "mesh3d"
with:
vb |
4 x n matrix containing n vertices as homolougous coordinates |
it |
3 x m matrix containing vertex indices forming triangular faces |
normals |
4 x n matrix containing vertex normals (homologous coordinates) |
in case the imported files contains face or vertex quality, these will be stored as vectors named $quality (for vertex quality) and $facequality
if the imported file contains vertex colors and readcolor = TRUE, these will be saved in $material$color according to "mesh3d" specifications.
currently only meshes with either color or texture can be processed. If both are present, the function will mark the mesh as non-readable.
