.SH NAME
|
||
|
|
.B ctmconv
|
||
|
|
- file format converter for 3D models
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.B ctmconv
|
||
|
|
.I infile outfile [options]
|
||

|
.SH DESCRIPTION
|
||
|
|
.B ctmconv
|
||
|
|
is a 3D file converter that can convert 3D model files to and from several
|
||
|
|
different formats.
|
||
|
|
.PP
|
||
|
|
The file
|
||
|
|
.I infile
|
||
|
|
is loaded, and then saved as
|
||
|
|
.I outfile
|
||
|
|
in the target file format.
|
||
|
|
.PP
|
||
|
|
The input and output file formats are determined from the file endings.
|
||
|
|
.SH OPTIONS
|
||
|
|
The following options are available:
|
||
|
|
.TP 16
|
||

|
||
|
|

|
||
|
|
.TP
|
||
|
|
.B --upaxis arg
|
||
|
|

|
||
|
|
.TP
|
||
|
|
.B --flip
|
||
|
|
Flip triangle orientation.
|
||
|
|
.TP
|
||
|
|
.B --calc-normals
|
||
|
|
If the source file does not contain any normals, calculate them.
|
||
|
|
.TP
|
||
|
|
.B --no-normals
|
||
|
|
Do not export normals.
|
||
|
|

||
|
|
Do not export texture coordinates.
|
||
|
|
.TP
|
||
|
|
.B --no-colors
|
||
|
|
Do not export vertex colors.
|
||

|
.B --comment arg
|
||
|
|
Set the file comment (default is to use the comment from the input file, if

|
||
|
|
.B --level arg
|
||
|
|
Set the compression level (0 - 9).
|
||
|
|
.TP
|
||
|
|
.B --vprec arg
