Indigo's ability to dynamically edit scene data allows for realtime camera movement, which is very useful for final tweaking of a shot, or simply exploring the scene with full lighting.
There are two ways to effect realtime camera changes: via the on-screen buttons, and via keyboard and mouse controls.
Using the on-screen buttons
To use the on-screen buttons, click and drag on the buttons in the top-right corner of the main render and OpenGL preview windows:
|Rotate||Rotates the camera's view direction.|
|Pan||Pans the camera.|
|Dolly||Moves the camera forwards and backwards along the view direction.|
Using the keyboard and mouse
In the main render or OpenGL preview window:
|Hold Alt + left mouse button, drag||Rotate||Rotates the camera's view direction.|
|Hold Alt + middle mouse button, drag||Pan||Pans the camera.|
|Hold Alt + right mouse button, drag up/down||Dolly||Moves the camera forwards and backwards along the view direction.|
Holding the Shift key while performing these actions reduces the mouse sensitivity, for more fine-grained control.
Mouse sensitivity and inversion options can found in the Options dialog, in the "OpenGL and Controls" tab.
