Geometry can be imported using either the Wavefront OBJ, Autodesk FBX, or Alembic file formats (as well an an internal format). Note: Deformable object tracking will perform best when the subject is facing the camera, is illuminated evenly, and covers a large proportion of the image area. When deformable tracking is not being used, there is no real advantage to using a very high resolution model compared to a lower resolution model that still approximates the geometry fairly well. The resolution of the mesh only has an impact when tracking deformable geometry because individual triangles must be assigned to different tracking groups. Note that the geometric mesh model should be a good approximation of the object that is being tracked, although it does not have to be exact. Meshes can be imported using either the Wavefront OBJ, Autodesk FBX, or Alembic file formats, and saved using an internal file format that maintains all group assignments and vertex weights. Helpers can also be of use in situations where the lighting on an actors face is such that automatically tracking the motion over a large number of frames becomes difficult.Д®ach vertex of the mesh can be assigned a weight, corresponding to how much influence that vertex has towards calculating the overall motion of the object or camera. Helpers (in the form of manually tracked points passed into the Geometry Track node from a User Track node, can be activated to assist with tracking quickly moving objects where the mesh might otherwise drift because of difficulty in following the image data. Groups are created automatically when an imported Wavefront OBJ file contains group definitions. Deformable tracking groups can be created or deleted, and modified by painting with a brush in a window. This can be achieved by creating one or more deformable tracking groups, assigning some of the triangles in the mesh to those groups, and specifying how the groups can transform relative to the rest of the mesh. The Geometry Track node can also be used to track a deformable object like a talking face. In many cases, a simple object such as a flat rectangle or a cube can be used to track part of a background set. Geometry tracking can also be used to track the motion of a camera relative to the set if a model of (part of) the set is available. In its basic mode of operation, the object being tracked must be undergoing a rigid transformation consisting of changes to its translation, rotation and scale parameters. This can be useful in situations where it is either not possible or not desirable to track using multiple tracking points.ДЇor example, if a geometric model of an actor's head or arm is available, that body part can be tracked very quickly and easily using the Geometry Track node. The Geometry Track node can be used to track either the camera or a moving object using a triangular mesh instead of tracking points. Solving for camera pose and 3D point cloud.The auxiliary anchor snaps to features while you are scaling. The selection anchor and auxiliary anchor both use the current snapping environment when you are dragging them. Move the pointer over it, then drag the auxiliary anchor to the desired location. Press the S key to turn on/off the auxiliary anchor. While scaling features, you can use the auxiliary anchor to snap the features. When the selection anchor is moved, the feature is scaled much differently. The graphics below show the result of scaling with the selection anchor in the center of a feature (left graphic), and with the selection anchor moved to the bottom of the feature (right graphic). However, if you move it to another position, the scaling is anchored to the selection anchor's position. If the selection anchor is in the middle of the feature, it is scaled equally from the center. Scaling is performed based on the location of the selection anchor (the small x located in the center of selected features). The right shows the polygons after being scaled, so they are now the appropriate size. The left image shows two selected polygons that should fit within the gap left by the adjacent polygons. You can use the Scale tool to scale parcels so that they fit together properly.

You might use the Scale tool when working with data for which the scale is slightly inaccurate-for example, subdivision parcels from multiple sources. You can scale a feature-make the entire feature larger or smaller-using the Scale tool.
