CamPoints let you pinpoint locations on a background. They are for use with the Camera Tracker and Camera Match utilities.
CamPoint helper objects are used by the Camera Tracker and Camera Match utilities to reproduce in a camera the same settings (position, roll, and FOV) that were used by a real-world camera to shoot a background image. This allows you to view your scene from the same perspective as the background image, which is a key step to mixing computer-generated and photographically-generated images in a single composited shot.
Place CamPoint objects in the scene at locations that will be visible in the background photograph. By comparing the X/Y/Z position of several camera point objects to their analogous positions in a background image, the Camera Match utility is able to determine the real-world camera’s settings, and use these settings to either create a new camera or move/reset an existing camera to match them.
Clicking CamPoint displays the Keyboard Entry and Camera Match Point rollouts, which you use to create and name the camera points.
To create a camera match point:
You are now ready to create a camera point.
To position camera match points in your scene, do one of the following:
Lets you name the CamPoint object before you create it. If you want to name it after you create it, change its name in the Modify panel.
Let you enter the X, Y, and Z coordinates where a CamPoint object will be inserted. Field values reflect the current Unit setup.
Inserts the CamPoint object into the scene.
Controls whether an axis tripod is displayed with the Camera point object. Default=on.
Controls the length of the axis tripod. When Show Axis Tripod is on, you can watch the tripod change length in the viewport while you adjust the spinner arrows. When Show Axis Tripod is off, you can adjust the Axis Length value, but the axis tripod won't be displayed.
