OutputsProjection mapping

Visuals on walls, boxes and columns.

Choose Projection mapping under OUTPUT → Arrangement. On the picture of each projector you lay canvases: shapes that follow walls, boxes and columns. Outside the canvases the projector stays black.

1. Arrangement Projection mapping.
2. A corner: drag it onto the edge of the object. The front of the box is selected (pink).
3. A canvas with a 3×3 grid bends around the column.
4. A mask blacks out the door.
5. + Canvas adds a surface.
6. + Mask adds a black-out area.
7. Alignment grid on all canvases, distorted, to match edges exactly.
8. Snap on or off.
9. Stage photo as a guide behind the canvases.
10. Name of the canvas, which picture it shows and the shape (4 corners or grid).

1. + Canvas adds one. Drag a corner to fit it to a wall, a box or a trapezoid, drag the middle to move it. Arrow keys move by 1 px (with ⇧ 10 px).

2. Grid for alignment lays the grid test pattern distorted onto the canvases, so the edges can be matched exactly.

3. Shape: 4 corners, or a 3×3 or 5×5 grid for round and curved surfaces; every point can be dragged and the surface bends smoothly.

4. + Mask draws a polygon (up to 32 points): black it out (door, window, person) or show only the inside, with a soft edge.

5. Stage photo … puts a photo of the stage (best taken from the projector) behind the canvases as a guide. It never goes to the projector.

Pictures

Up to five pictures, each with its own layers, clip grid and effects. Each canvas chooses which picture it shows, whole or a part. Scenes save and recall all pictures with a fade. In VISUALS the pictures appear as live tiles; a click edits one.

Desk channels 71–75 set the brightness of the pictures, 76–91 the opacity of their layers 1–4. MIDI and OSC can do the same with fixed controls per picture.
