mayaMatchMoveSolver-v0.4.0.alpha6

DO NOT USE THIS IN PRODUCTION!!!
This version of mmSolver is for testing only!

This is a feature incomplete and buggy release of the upcoming v0.4.0 release of mmSolver.

The alpha 6 release focuses on usability of various tools and features in mmSolver, including the mmSolver image plane (mmImagePlane), the "MM Scene Graph", the "Camera Context Menu", and other improvements and fixes (see below).

---

Load mmSolver in Maya 2022

To load mmSolver on Maya 2022 you must run the following MEL command:

mmsolver_load

This will load the mmSolver plug-in, and allow you to automatically load the mmSolver plug-in and will ensure it is loaded each time Maya is started.

If you wish to unload mmSolver so it will not be loaded at Maya start-up run the following MEL command:

mmsolver_unload

These new commands were added to work-around the new Maya 2022+ Security preferences and ensure mmSolver will be loaded when it's needed.

Additionally the Python module mmSolver.startup was added, and allows pipelines to manually load mmSolver with the Python commands:

import mmSolver.startup
mmSolver.startup.mmsolver_startup()

---

Features / Changes

The main changes in this release:

• (#173) mmImagePlane
  • Add first frame attribute to control frame offset.

mayaMatchMoveSolver-v0.4.0.alpha5

DO NOT USE THIS IN PRODUCTION!!!
This version of mmSolver is for testing only!

This is a feature incomplete and buggy release of the upcoming v0.4.0 release of mmSolver.

The alpha 5 release improves the mmSolver image plane (mmImagePlane) by ensuring a new shape node to control the display of the textured image plane in wireframe and shaded modes.

To help the mmSolver image plane workflow a Camera Node Context has been added to the shelf (button "NdCtx") which will dynamically provide access to the active camera, image planes and lens distortion "layers" - including common options.

mayaMatchMoveSolver-v0.4.0.alpha4

DO NOT USE THIS IN PRODUCTION!!!
This version of mmSolver is for testing only!

This is a feature incomplete and buggy release of the upcoming v0.4.0 release of mmSolver.

This release offers substantial performance increases (between 2 to 20 times faster!) with the "MM Scene Graph" mode, and solving of Lens Distortion (static and animated) attributes also supported.

Visualizing Lens Distortion is also easier than alpha3, with a new Camera Tools > Create Image Plane tool which includes a nicer Attribute Editor UI for the (new) mmImagePlaneTransform node.

The Standard solver's "Root Frames" feature has finally been implemented as originally envisioned. "User Frames" and "Root Frames" are available with an automatic calculation of the needed in-between frames for a stable solve with the given Markers. the options to compute the root frames are exposed to adjust the speed/accuracy of the solve. The defaults should provide a good solve "out of the box", without users needing to add user frames.

Please report any bugs or suggestions you find in this release here and clearly state the version of mmSolver you are testing.

mayaMatchMoveSolver-v0.3.16

Release v0.3.16 provides support for Maya 2022 (Python 3 - #217), support for importing PFTrack .txt/.2dt files with the Load Markers tool (#239), as well as bug fixes and minor changes.

For installation with Maya 2022, please see the special section in the INSTALL.md file.

Download the archive file for your operating system and Maya version, and follow the INSTALL.md instructions.

---

New Features

• (#217) Maya 2022 (Python 3) support is now provided
  • Make sure to load the mmSolver plug-in manually in Maya 2022, because startup scripts no-longer work.
  • See INSTALL.md file. for more details.
• (#239) Loading 2D Trackers exported from PFTrack with the native .txt/.2dt files is now supported.
  • Note: the PFTrack .txt/.2dt files are resolution dependent and do not support much of the advanced features of the Load Markers tool.

Bug fixes

• (ab1c61d) Fix "node affects relationships" when calculating how Markers and Bundles affect each other.
• (621f8a5) Fix possible minor Solver UI marker bug.

Changes

• (#237) Change default marker group depth from 10 to 2 units from camera.
• (7f4aea6) Darken image plane file for Camera Calibration.
  • This is to allow the user to see the lines/locators on top of the image.

Developer Notes

• As a result of the Maya 2022 security preferences, a new Python module mmSolver.startup has been created which contains most of the functions in the userSetup.py file responsible for loading mmSolver components in previous releases. This new module should be called to load mmSolver components. For versions of Maya before Maya 2022 the userSetup.py is maintained for backwards compatibility, however the functions are deprecated.

Known Issues

• Documentation is not included in the Linux build of mmSolver for v0.3.16. The online documentation is available instead.
• As of v0.3.15 mmSolver is no longer supported on MacOS, and per-compiled versions are not provided.
• Evaluation
  • Solver engine can become slow with many attributes.
  • The Maya viewport is refreshed during solving to force Maya to evaluate all nodes in the solve. This causes slower performance (e.g. 6 seconds verses 30 seconds), but ensures accurate solver results. Users may wish to turn this feature off in the Solver UI > Edit > Refresh Viewport check box.
• Maya 2016
  • Maya 2016 is unsupported by the mmSolver project, we are not able to provide testing for Maya 2016.
  • On Linux has problems with the new user preferences UI - the release for Maya 2016 is available for download, with this limitation.
  • the Solver UI disables selection of the Attributes - the cause is unknown.
  • The mmSolverType command raises an error with certain flags on Maya 2016 for an unknown reason. This problem is specific to Maya 2016, the same command works on Maya 2017+.
• Compatibility
  • New v0.3.0 default values will not be used until a new Collection is created. Delete your previous Collection and create a new Collection using the Solver UI > File > New Collection menu item.
• Development/Building:
  • The test suite fails on 3 different solver tests, due to a deviation that is too high, this is intentional and will be fixed in a future version.

mayaMatchMoveSolver-v0.4.0.alpha3

DO NOT USE THIS IN PRODUCTION!!!
This version of mmSolver is for testing only!

This is a feature incomplete and buggy release of the upcoming v0.4.0 release of mmSolver.

This release contains fixes for Maya 2022 / Python 3, a new (2D) "Line" object type and an accurate "live" image plane to preview 3DEqualizer lens distortion.

The 2D Line is intended to be used to align to straight edges in a plate and then be used to solve lens distortion without any 3D (Bundle) information.
The lens solving part is not yet implemented, however the 2D Line can be used to visualise the line while you manually adjust the lens attributes.
This new 2D Line object is also integrated into the Camera Calibration set up (first introduced in v0.3.15).

The "live" image plane has been improved with a traditional "baked" (non-editable) image plane option and can be toggled with an attribute on the transform node (see the "Extra Attributes" roll out).
The lens distortion effects on the live image plane are accurate to the 3DE "classic" lens distortion model, so values from mmSolver can be (manually) typed into 3DEqualizer, Nuke or Natron and produce the same lens distortion effects.

mayaMatchMoveSolver-v0.3.13

Release v0.3.13 adds support for Maya 2020 on Windows and Linux, and adds some very helpful and long-overdue new tools; the Center 2D offsets, Create/Remove Controllers v2, Screen-Space Rig Bake, and Bake Attributes tools.

Unfortunately, this release also removes support for Maya 2016. The plug-in is untested on Maya 2016.

Download the archive file for your operating system and Maya version, and follow the INSTALL.md instructions.

Known Issues

• Evaluation
  • Solver engine can become slow with many attributes.
  • The Maya viewport is refreshed during solving to force Maya to evaluate all nodes in the solve. This causes slower performance (e.g. 6 seconds verses 30 seconds), but ensures accurate solver results. Users may wish to turn this feature off in the Solver UI > Edit > Refresh Viewport check box.
