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.
