Maya Tool - Convert 3D Transform to Screen-Space

[david-cattermole]

Problem

While solving or cleaning up matchmove cameras it can be helpful to manipulate a transform in screen-space (for example manipulate Screen Z-Depth).

Steps

1. Select Maya Transform Node(s).
2. Activate 3D Viewport.
3. Run tool; transform is baked under the camera.
4. Delete Animation on 3D Transform.
5. Point Constrain Screen-Space Transform to 3D Transform.

Notes

• We can use the maya.cmds.mmReprojection command to calculate the screen-space values.
• We can use "Marker Group" nodes under a camera to convert a normal Maya 3D transform node into screen-space.

This tool is now working and merged into the master branch.

We may need to revisit the lib module, to ensure we can bake a tool via mmSolver.tools.screenzbake.lib.

We may also rename the module in future, screenzbake isn't only what the tool is doing.
