Description

Use to read an rotation from a file. Command will fail if at the end of the file.

The following is a listing of the different cast types. Note that data can be lost when casting. 'Signed' means the value can be negative. 'Unsigned' means value will always be positive.

Cast	Description
`c`	Reads a series of signed characters, or signed 8-bit (1 byte) values, and converts them to floats
`uc`	Reads a series of unsigned characters, or unsigned 8-bit (1 byte) values, and converts them to floats
`s`	Reads a series of signed short integers, or signed 16-bit (2 bytes) values, and converts them to floats
`us`	Reads a series of unsigned short integers, or unsigned 16-bit (2 bytes) values, and converts them to floats
`i`	Reads a series of signed integers, or signed 32-bit (4 bytes) values, and converts them to floats
`ui`	Reads a series of unsigned integers, or unsigned 32-bit (4 bytes) values, and converts them to floats
`f`	Reads a series of floating point values, a 32-bit (4 byte) values, and converts them to floats

Command syntax

Syntax

readRot fileID [-delim string] [-quat] [-rotOrder string] [-cast string] [-rad]

Arguments

Name	Type	Required	Comments
`fileID`	int		ID of file previously opened with fileOpen

Flags

Name	Flag arguments	Argument type	Exclusive to	Comments
`delim`	1	string	—	Delimiter to expect between rotation channel values. Cannot be used with binary files. Usually "," or "\t", etc.
`quat`	0	—	rotOrder	Specifies that the rotation should be expected as a quaternion (four float values) rather than an Euler angle (three float values). Can not be used with `-rotOrder` option
`rotOrder`	1	string	quat	Specifies the rotation order that the rotation will be expected in. Can not be used with `-quat` option (possible values are XYZ, XZY, YXZ,YZX, ZXY, and ZYX)
`cast`	1	string	—	Data type to cast to. Possible types are listed above. Note that data can be lost when casting.
`rad`	0	—	quat	—

Return value

vector

Examples

//Read Rot Example
vector $rot;
int $fileID;
int $fileID = `fileOpen "C:/FileTesting.txt" "r"`;
  
// Read the rotation as an Euler angle
// The -delims flag assumes you are reading from a text file 
$rot = `readRot $fileID -delim ","`;
  
// Or, read the rotation as a quaternion
// The -delims flag assumes you are reading from a text file 
$rot = `readRot $fileID -quat -delim "\t"`;
fileClose $fileID;
  
// Display the value
print $rot;
