# One projector. One clear visual idea. Canonical: https://phasevoid.com/journal/one-projector-stage-design/ Published: 2026-10-11. Updated: 2026-10-15. By [Balance IT](https://balanceit.pl). Category: Stage composition. Treat the stage as one composition. Several surfaces are useful when they work together and leave the strongest image room to breathe. ![Spectral organ reference still](https://phasevoid.com/scenes/spectral-organ.webp) Spectral organ · an industrial surface reference. The image is a Studio still, not a photograph of a projector or a calibrated venue. ## Workshop: One focal image, two supporting wings Make one focal sculpture read clearly against two quieter, independent supporting regions in a single projector picture. Starting frame: 16:9 · 1280 × 720. Motion: Gentler. Audio: your file, chosen separately. | Role | World | Exact starting choice | | --- | --- | --- | | Focal sculpture | Chrome knot | Booth front · Opacity 100% · Motion 100% · Energy 110% | | Supporting texture | Spectral organ | Left wing · Opacity 55% · Motion 45% · Energy 80% | | Tall region | Liquid spire | Right wing · Opacity 55% · Motion 45% · Energy 80% | [Rehearse the focal stage layout](https://phasevoid.com/studio/?journal-exercise=one-projector-stage-design). Opening the exercise starts no audio, selects no file and grants no input permissions. ### Three steps to rehearse it 1. Review before Load exercise: it replaces look, output, mapping, acts, MIDI and clip settings. Undo exercise restores earlier settings in this tab until reload; reattach video files separately. Audio remains under its own controls. 2. Choose your audio, open Mapping and align the booth and wings to the actual targets. Starter corners are a design starting point, never a calibrated room. 3. Inspect the central sculpture and both supports from the audience position. Tune one surface off air, Take deliberately, then save and rehearse the final mapped output. ### What to look for - Does the focal sculpture hold attention while the wings support its rhythm? - Do gaps, crops and overlap remain intentional in bright and dark passages? One output contains three surfaces; this is not three projector routes. The illustration remains a composition sketch. Physical alignment, room brightness and endurance require venue checks. ![Actual decoded three-surface workshop frame](https://phasevoid.com/media/examples/journal-stage-workshop-1.57.webp) Actual decoded output: 1280 × 720, three sources, from a two-second browser render with the original test WAV. This is not a photograph of a calibrated venue. Checked in native Chrome on 14 October 2026: explicit load/undo, four manual acts, three real frame shapes, sequential A/B and a saved/reopened public-reference brief. A separate two-second mapped film decoded to 48 different frames. [Read the bounded software check](https://phasevoid.com/evidence/journal-workshops-2026-10-14.json); physical projection and long-set acceptance remain separate. Keep the mapped layout in Studio, or carry the public three-surface direction into a separate custom-work brief. [Discuss this stage direction](https://phasevoid.com/custom-visuals/#brief-context=%7B%22version%22%3A1%2C%22source%22%3A%22example%22%2C%22kind%22%3A%22journal%22%2C%22exercise%22%3A%22one-projector-stage-design%22%2C%22frame%22%3A%2216%3A9%22%7D). The brief receives the public layout and all three world roles, not your room calibration or private settings. Custom work is quoted separately; public Studio tools stay free. ## Choose where the eye should land. Sketch the booth, panels or wall areas before assigning worlds. Mark one focal region. It could be the centre of the booth, a suspended shape or the largest clear area of a wall. The surrounding regions should explain that choice through direction, scale or restraint. A useful first arrangement is a strong central image with two quieter wings. The centre may hold a reflective sculpture while the sides use a texture with a related palette. The wings can support the rhythm without asking the audience to inspect three equally complicated subjects at once. An alternative is one continuous image divided across panels. Use **Program** as the source and adjust crops when continuity matters. Use an **independent procedural world** when a surface needs its own look. Those decisions change the composition; more surfaces do not automatically create more impact. ## Design for the gaps as well as the surfaces. Composition sketch: one focal booth region, two supporting wings and intentional empty gaps, all within one final output. This is a design sketch, not calibrated geometry. The diagram is a composition sketch, not calibrated geometry. Keep empty regions intentional. A narrow dark gap can separate a moving wing from the focal image. A large unused wall can help one sculpture read clearly. If every available region contains bright detail, the outline of the installation can become harder to see. Check the shape of each target. A wide booth front may suit a travelling texture; a tall wing may suit a vertical form; a central panel may suit a single object. Crop a source for its strongest useful region instead of forcing every surface to show a complete landscape picture. - **Focal sculpture: [Chrome knot](https://phasevoid.com/studio/?scene=chrome-knot&ratio=16%3A9)** — One interlocking reflective body to inspect at the centre. - **Supporting texture: [Spectral organ](https://phasevoid.com/studio/?scene=spectral-organ&ratio=16%3A9)** — A cable wall with travelling packets that can fill a broad region. - **Tall region: [Liquid spire](https://phasevoid.com/studio/?scene=liquid-spire&ratio=16%3A9)** — A vertical lobed form to audition for a narrow wing. ## Give every surface a job before adding effects. In PHASE//VOID, independent surfaces can have separate worlds, looks and surface effects. Start with those sources at neutral FX settings. Match their visual weight first. Then use an effect because it solves a composition problem: a small RGB split for a charged edge, pixelation for a coarser texture, or kaleidoscope for a repeated form. Compare a candidate for the focal region before changing the picture the audience sees. In **Surface Look Studio**, search worlds and tune a copied source look and surface FX off air, then take it to the named surface when ready. Follow the [surface-draft workflow](https://phasevoid.com/guides/live-visuals/#surface-look-draft) for the controls and performance locks. Its muted preview shows the source rather than the calibrated stage: crop, masks, overlapping regions, clips and master effects still need a check on the final output. Keep the distinction between **Program FX** and **Surface FX** clear. Program includes the main composition, clips, title and artwork. Independent procedural sources use their own worlds and racks. All surfaces share the connected audio and selected pulse. They are parts of one final output, not independently controlled video players. Opacity and blending can help overlapping regions, but an overlap should have an intended result. Inspect it with ordinary visuals as well as a test pattern. Feather softens a mask edge; it does not calibrate brightness between separate projectors. ## Let the real room make the final decision. Give the operator a clear view as well. Prepare sources and geometry in Studio, then use **Stage view** and **Hide controls** to watch the full composition. Reveal Mapping for adjustments; a workspace divider resizes the inspector, while surface handles change geometry. Those are different actions. **Back to Studio** restores the editor and libraries. Follow the [Stage workspace and recovery instructions](https://phasevoid.com/guides/live-visuals/#stage-workspace), including the actual before/after layout evidence. Enlarging a preview does not raise output resolution or prove venue alignment. 1. Fix projector position, output frame and display arrangement before fine alignment. 2. Use calibration patterns to align surfaces in the actual room, then turn the pattern off. 3. Inspect a bright passage, a dark passage and a transition from the audience position. 4. Reduce detail or the number of distinct sources if the actual setup cannot keep the motion usable. 5. Save the map and a session after rehearsal. Keep the source media separately available when clips are involved. The complete controls, geometry limits and source budget are documented in the [single-projector mapping guide](https://phasevoid.com/guides/live-visuals/#mapping). Studio supports up to eight surfaces in one raster. It does not provide multiple projector routes, 3D mesh mapping or projector edge blending. > A clear browser preview cannot establish physical alignment, perceived brightness or sound-to-screen timing in your room. These depend on the projector, target material, placement, surrounding light and signal chain. Begin with one focal surface and add a supporting region only when it improves the picture. That makes the first setup easier to align, easier to rehearse and easier to recover during a set. ## Try the idea [Rehearse the focal stage layout](https://phasevoid.com/studio/?journal-exercise=one-projector-stage-design).
