That leaves a lot of freedom to define individual setups for very different kind of moves.īut what is equally of interest as the mesh generation itself is its application. Apart from the other features, which work iteratively (meaning that you can only track the Shear if you also got Transform, Scale and Rotation active), Mesh can be selected even if not all previous options have been selected. But below that is a new button simply called “Mesh”.

There are the well known options for Transform, Scale, Rotation, Shear and Perspective. You set up your spline and define the kind of movements you want the tracker to consider for its solve.

This is especially nice in regard to setting up the “Smoothness” value for a mesh, which in essence allows you predefine the rigidity of the object you’re tracking.įrom a user interface point of view, not too much has changed. But those have their own individual draw backs, one big that they are fairly processor intensive, the other one is that it is a lot less controllable than a traditional point or planar tracker.Īs with a lot of the other features in Mocha, PowerMesh lets the user decide on most parameters whether Mocha should guess the appropriate values or if the user wants to set them up for themselves. That is why in recent years optical flow solutions based on motion vector estimation have become the favored solution for these kind of tracking scenarios. While planar trackers like Mocha have always excelled at tracking rigid surfaces such as a billboard, license plate, and the ever-popular screen insert, tracking organic surfaces like skin, cloth or paper has always been a hit-and-miss scenario combined with a lot of manual, tedious labour. This mesh allows something which up until now has always been a weak point of planar tracking. Points can, of course, also be added manually to both kinds of meshes. This mesh is either generated by Mocha automatically using areas where there is a lot of warping and/or contrast as points for the mesh or the mesh can be uniformly generated by the user.

While that’s a mouthful, what it in essence means is that you can track a mesh of points inside a defined spline. With Mocha Pro 2021, a new feature is introduced: PowerMesh sub-planar warp tracking.
