5.6.4 Elevation Snap Modes

Elevation Snap mode refers to the automation playlist that supports three modes that

change the shape of the ceiling in the room, and in turn, how elevation drops as objects

are panned away from the ceiling.

• Ceiling Elevation gives the room a flat ceiling in the back 80% of the room and a

curving ceiling from the front 20% of the room to the screen.

• Sphere Elevation gives the room a domed ceiling.

• Wedge Elevation gives the room a peaked ceiling.

You can automate Elevation Snap modes in Pro Tools by using the Elevation Snap mode

automation playlist. Elevation Snap mode has four states: ceiling elevation, wedge

elevation, sphere elevation, and off.

Ceiling Elevation

Ceiling elevation links the z elevation to the y coordinate to form a flat ceiling inside the

Panner virtual room that curves from the front 20% of the room to the screen. The

elevation is constant in the back 80% of the room. Elevation drops uniformly as objects

are moved away from the front 20% of the room to the screen. Left or right movements

on the x-axis do not change the object elevation.

To use ceiling elevation:

1. Turn on ceiling elevation by doing one of the following:

• Click the elevation snap selector, and select (highlight) the ceiling elevation icon.

• Use a control surface or iPad.

2. Adjust elevation by moving the y coordinates with any of the following:

• Joystick.

• Control surface or iPad.

• Mouse (on the pan location cursor or

Y slider).

To disable ceiling elevation mode, do one of the following:

• Click (unhighlight) the ceiling elevation icon.

• Turn on Elevation mode or another Elevation Snap mode.

• Use a control surface or iPad.

You can automate ceiling elevation on and off in Pro Tools by using the Elevation Snap

mode automation playlist.
