Using the PointsTo3D node

The previous demo video showed the theory of operation for the PointsTo3D node.…Here, we'll see how to set it up and track a 2D point even as it goes out of frame.…We're going to need to clip the track,…so we'll type R for the Read node, select our Project…Media>Lesson_4_Media>cube.mov.…This is a little training clip that I made to help teach the PointsTo3D movie.…We'll open that, hook it up with the Viewer, a little more screen space please.…

You'll note that our target which is going to be right here, the intersection of…these two lines, goes all the way out of frame.…So we're going to see how easy it is to get tracking data even out of frame. Okay.…Let's add a Camera.…Come up to our 3D tab, select Camera.…Now, we need a camera solve, so we need our camera data, we've got that, too.…So we'll go to the Camera tab, this is our folder for Importing Chan File data.…We'll select our Project Media folder>Lesson_4_Media again, and the…cube_camera.chan file.…

Open that, and our camera is now animated on every single frame.…
