Placing cameras in the viewer ¶
There are three ways you can place cameras in the scene view. They can be moved once they are placed by either dragging them in the scene view or changing the values in the parameter editor.
To... | Do this |
---|---|
Place cameras in a specific location in the scene view |

Place a camera by looking through it |
When looking through the camera there are handles on the sides of the scene view which allows you to orient and crop.

Handles ¶
Clicking on cameras in the scene view gives you more camera and light manipulator handle options. The two that are unique to cameras are the focus handle and the frustum handle.
Frustum handle
Allows you to set the near and far clipping planes and the focal length.
Focus handle
Allows you to control the depth map focus.
