Mapping

Content goes on by

Or drag the orange figure in the 3D view, or click and drag on the plan ("From above").

Viewer across (m) Eye height (m) Distance from the wall (m)

Across from the wall's middle, distance out from the line between its two ends.

Viewer across (m) Eye height (m) Towards the screen (m)

Measured from the screen's axis; 0, 0 is the centre of the curve.

Direct wraps the content round the curve. Perspective makes it a flat picture, square on, from that eye; it bends for everyone else. Parallel pushes it straight out from the viewer's direction, the same size at any distance, so it reads flat-ish from anywhere in front. The names follow disguise's mapping types. Pick the "Flat chart" pattern and the "viewer" view to check.

Panels

Panel width (mm) Panel height (mm) Pixels across a panel Pixels down a panel Panels across Panels high Bottom edge off the floor (m) Weight per panel (kg) Max power per panel (W)

Weight and power from the panel's datasheet; leave 0 to skip the totals.

Curve

Angle at each joint (°) Direction

Concave wraps round the audience; convex bulges towards them. Change any single joint under "Joints". 0 is flat.

Output

Content fits the map by Panel numbers on top Output width (px, 0 = map) Output height (px, 0 = map) Map starts at x (px) Map starts at y (px)

Where the pixel map sits in the frame your processor takes, top left being 0,0. Leave 0 to send the map on its own.

Screen

Radius (m) Arc covered (°) Height (m) Side

Projector

Aims at (°) Distance from axis (m) Lens height (m) Tilt (°, up is +) Throw ratio Lens shift up (%) Output width (px) Output height (px)

Concave: how far behind the axis the projector sits, away from where it aims (negative is in front). Convex: distance from the column's axis.

In 3D

Drag the orange figure to move the viewer: in top view across the floor (aerial), in side view forward, back, up and down (side profile), in front view sideways, up and down. Drag anywhere else to turn the view, scroll or pinch to zoom, right-drag to move. Front, top and side are near-flat views, like a drawing. The figure is 1.75 m.

Output no output window

The output window shows this frame at one pixel per pixel, top left. Put it on the display that feeds your LED processor or projector and click it to go full screen. To send it over NDI, capture that window with NDI Screen Capture or OBS.

TouchDesigner: Save the UV map and the script into your project folder. In TouchDesigner, make a Text DAT, load the script, right-click it, Run Script. It builds content → Remap TOP (the UV map in its second input) → out, using TouchDesigner's own operators. Point cm_content at your video.
Notch: Composite Image post effect: your content in Image, the UV map through a Video Loader into UV Remap Image. Notch's manual doesn't say which way up it reads v: if the picture comes out upside down, flip the map vertically. The 3D model (OBJ) also loads into Notch for previz.
Resolume: Not yet: Resolume has no UV-map input. Its native route is an Advanced Output slice file, one slice per panel, coming next. Meanwhile capture Resolume's output here as "Screen or window" and send this page's output window to the wall.
What the map is: For each pixel you send, red is where across the content to read (0 left, 1 right) and green where up (0 bottom, 1 top); alpha is 0 where nothing lands. LED: the size of the pixel map. Projector: the size of the projector frame. With Perspective or Parallel mapping chosen, that mapping is baked in.

Joints, left to right as you face the wall

A joint is where two panels meet. Joints you have changed from the common angle are outlined.
