Create menu > Helpers > Camera Point
The CamPoint helper lets you create camera points in your scene. These points are used by the Camera Match utility to match the camera with a photographic background. The virtual camera is positioned to mimic the position of the actual camera that was used to take the photograph.
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:
-
Choose Camera Match from the list and click the CamPoint button in the Object Type rollout.
The button turns yellow when it is active. You are now ready to create a camera point.
-
Click in the viewport to create a CamPoint helper object. Alternatively, you can use the keyboard to create a CamPoint object by expanding the Keyboard Entry rollout, entering values in the fields, and then clicking Create.
To position camera match points in your scene, do one of the following:
-
Create your camera match points using keyboard entry. Use this if you have accurate actual measurements of the locations of the points.
-
Build geometry that matches your scene geometry, and then snap the points to the geometry using snaps. Use this technique when you don’t have measurements and can approximate the geometry.
-
Create your camera match points interactively, and then use Transform Type-In to move them to the correct locations.
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.
X, Y, Z—Let you enter the X, Y, and Z coordinates where a CamPoint object will be inserted. Field values reflect the current Unit setup.
