Screen placement
Tilt = pitch about the width axis · Yaw = rotate about vertical · Roll = spin about the screen normal (same axes as the LED calculator).

Fulldome studio — dome & projector rig
1 · Dome geometry
2 · Projector rig — auto lens & layout
Pick a projector model — its native raster and real lens set drive the auto lens, throw ratio and FOV. Each projector is fitted to cover its slice of the dome from the uncovered-base line up to the top. Any change here updates the dome and rig live. Lens/throw are geometric estimates; verify against the manufacturer lens calculator.
Tip: the dome and rig preview live in the 3D view behind this window as you change values. Click “Done” (or ✕) to see the full result.
Export MPCDI
Screens / domes to include
Nothing to export yet. Sync from the calculator or generate a dome first.
Warp & blend
2D-profile MPCDI: one region per projector. Domes get a fulldome-master (fisheye) geometry warp; flat screens get a planar warp into that screen's output. Each region includes an edge-feather alpha blend. Experimental — verify orientation and blends in Watchout / your media server before show.
Copy projectors for WATCHOUT
Paste-able Watchout devices. Copy this text, then in a Watchout show press Ctrl/Cmd-V in the Devices/Stage to paste the rig. Dome + free/OBJ projectors come in as 3D Projectors (position, aim, lens/shift); flat screens as 2D displays. Positions are in mm.
