v.in.ply - GRASS GIS manual

Note: This addon document is for an older version of GRASS GIS that will be discontinued soon. You should upgrade your GRASS GIS installation, and read the current addon manual page.

NAME

v.in.ply - Creates a vector map from a PLY file.

KEYWORDS

vector, import

SYNOPSIS

v.in.ply

v.in.ply --help

v.in.ply [-tbp] input=name output=name [x=integer] [y=integer] [z=integer] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

-t: Do not create attribute table
-b: Do not build topology
-p: Only print PLY element types and their properties.
--overwrite: Allow output files to overwrite existing files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

input=name [required]: Name of input file to be imported; '-' for standard input
output=name [required]: Name for output vector map
x=integer: Number of vertex property used as x coordinate; First vertex property is 1; Default: 1
y=integer: Number of vertex property used as y coordinate; First vertex property is 1; Default: 2
z=integer: Number of vertex property used as z coordinate; First vertex property is 1. If 0, z coordinate is not used; Default: 3

DESCRIPTION

v.in.ply imports a vector map in PLY vector format. A PLY file always holds a number of vertices which are imported as points. PLY vertices can have a number of properties in addition to their coordinates. These properties are stored in an attribute table. For larger PLY files with many vertices (> 1000) it is highly recommended to not use DBF as database driver, but SQLite (default in GRASS GIS 7), PostgreSQL or MySQL, because the DBF driver is rather slow and can consume a lot of memory. The database driver can be set with db.connect.

NOTES

v.in.ply is designed for large point clouds with the possibility to have only coordinates, and no attribute table (for speed reasons).

EXAMPLES

v.in.ply input=myfile.ply output=myfile
