Now, let’s finally export our track data. If we want, we can use the grid to help us line up our corners.

Now we are free to move the corners to where we want to place our image. You will see that at the reference frame the planar surface is yellow. Let’s click the go to reference frame button, just in case we forgot where we started.

If we move the corner points at any other frame, we are actually applying corrections and we don’t actually want that. However, when doing this, we need to move the corners of the surface at what we call the reference frame, that is, the frame where we first started the track - in this case, frame 1. It’s also used to define where to place images in the scene.

This is a diagnostic plane you can use to spot when tracks start to fail and how to correct them. This displays what is called the planar surface, shown here in blue. I first make sure my post layer is selected, and then I click the correct plane button. To do this, I need to define where in the image I want the logo to be placed and then export my track data. Now, what I would like to do is insert this Nuke logo into our post track. We can also create whole new track layers, ready for drawing and tracking. This is extremely useful when we have multiple track layers. You can see if you select the track shape, the selector changes accordingly. This shows the currently selected track layer and its associated shapes. For now, the most useful knob here is the planar track layer selector. We look at all these in detail in later tutorials.

This is a context-sensitive toolbar to let you perform your entire tracking workflow from left to right, for example, tracking, display, and correction, and export, all without having to go back to any node properties panel. When a Roto or RotoPaint node has a PlanarTrackLayer, the tracking toolbar is now displayed in the Viewer. This means anything we put in the layer will be affected by the track. To be specific, they are keyed in the extra matrix knob for the layer. The PlanarTrackerLayer is also the place where the results of the track are saved to. If we want to, we can draw more shapes inside this layer, which will all contribute to the same track. Notice that the shape outline is colored purple to indicate it is in a track layer and will be used to define a region. In our example, we drew a shape for the top of the post. This is a special type of menu that is used to define what is being tracked. If we look inside the Roto node, we will see a PlanarTrackLayer in the curves menu. In fact, the Roto node is essential for the PlanarTracker to work, so always try and keep them connected. When we created the PlanarTracker, you will notice it also created a Roto node as well, this is to allow very tight integration of planar tracking with Roto. That Tracker is ready to use, but first let’s go over what happened. Right, so the tracking is finished, and if we scrub back and forth across the timeline, we can see it has done a very good job. For things like inserting images and set extension, it is nearly always faster and easier to use a planar tracker as opposed to some sort of projection in a camera solve, for example. This means you get a much more stable and accurate track compared to traditional 2D pattern trackers. The important thing to remember is that planar tracking tracks regions as opposed to small image patches. Our Tracker uses feature-based tracking it tries to find the best tracks that agree with the plane the user has drawn, and from those it derives a planar track. Things like walls, ceilings, and sides of cars are good examples of planar surfaces, but it can also handle non-planar surfaces, such as faces or people - generally, the more planar the surface, the better. The PlanarTracker follows flat surfaces where most points on the surface lie in the same plane. While it’s tracking, let me tell you more about the PlanarTracker. When we are done, we can click the Track Forward button and watch it track to the end of the shot. Once it is created, we can start drawing the area we want to track straight away. We start by creating a PlanarTracker from the Transform menu. In this shot, we want to track the top section of this post here. I’m going to start by demonstrating just how quick and easy it is to create a planar track, and then go into some of the basics of the PlanarTracker. Hello, my name is Dan Ring, and in this tutorial I’m going to show you how to use the new PlanarTracker found in Nuke 6.3.
