mmSolver.tools.savemarkerfile

Tool to convert a Maya Camera (and Image Plane) into a file format readable by third-party software (for example, 3DEqualizer).

The aim is to make the tool similar to the Load Markers tool, allowing minimal set-up time for getting data between Maya and 3DEqualizer.

Tool

The Save Marker File tool.

This tool will save the selected Markers to a .uv file, for loading in third-party software (such as 3DEqualizer).

mmSolver.tools.savemarkerfile.tool.main()

Library

The Save Marker File library functions.

Write out a mmSolver Marker node as a .uv file.

mmSolver.tools.savemarkerfile.lib.generate(mkr_list, frame_range)

Convert all Markers to data that can be written out.

Returns:

List of Markers

Return type:

[Marker]

mmSolver.tools.savemarkerfile.lib.write_file(file_path, data)

mmSolver.tools.savemarkerfile.lib.write_temp_file(data)

Write file.

Constants

Contains constant values for the Save Marker File tool.

The .uv format, resolution independent 2D tracking format.

This file supports only the .uv version 4 format.

The UV coordinate (0.0, 0.0) is the lower-left. The UV coordinate (1.0, 1.0) is the upper-right.

Format version 4:
