💡 Tip: Save your custom projector configuration to the library for easy reuse in future projects.
Create a room with 4 walls and a floor. Each surface can be controlled individually.
Room will be created with 4 walls and a floor. Each surface is independently selectable.
Create a rigging truss structure. Choose from professional Eurotruss presets or custom configuration. Use "Attach Projector" from the context menu to mount projectors after placement.
Presets include authentic Eurotruss specifications (main tube: 50mm, braces: 20-25mm, conical connectors)
Square (4-point): Standard box truss for heavy loads
Triangle (3-point): Lightweight, good for overhead
Ladder (2-point): Simple, cost-effective
Eurotruss sizes: HD44 (0.4 x 0.4m), HD34 (0.34 x 0.34m), FD32 (0.29 x 0.29m)
Trusses will be placed at the center of the scene at the specified height

Use this workspace to design projection layouts in 3D, validate feasibility, and prepare deliverables for clients and internal reviews.
Fast start: Add a surface ➜ place projectors ➜ align with transform tools ➜ validate with analysis + measurement ➜ save and export.
Use 📽️ Add Projector to open the library and place projectors in your scene.
Click 🎬 Screen / Surface and choose the geometry that matches your venue:
Select any surface to edit dimensions and shape options in the Properties panel.
Use 📷 Add Camera to place review/monitoring cameras and validate sightlines.
Select a camera preset or use 🎥 Add Generic Camera for rapid setup. Double-click any camera to open its live viewpoint.
Click 🧍 Reference Human to add a scale figure and quickly check stage, audience, and rigging proportions.
Select any object, then use transform shortcuts:
Use the gizmo handles for axis-constrained edits, or type exact values in the Properties panel.
Quick reference for all keyboard shortcuts. Press ? to toggle this help panel anytime.

💡 Tip: Use keyboard shortcuts for faster workflow. Combine transform shortcuts with the Properties Panel for precise adjustments.
Preview perspective-correct projection directly on 3D surfaces. Use overlaps, frustums, and test patterns to catch layout issues before installation day.
Auto-save: Edits are continuously preserved while you work.
Save project: Store named versions on the server.
Load project: Reopen previous plans at any time.
Export: Generate JSON/PDF/equipment outputs for reviews and handoff.
Press M or click Measure to activate measurement mode. Click two points on physical objects to see the distance in meters. Existing measurement markers are excluded from picking so they never interfere with new measurements.
Use Clear to remove all measurements.
Select any object to edit dimensions, transforms, lens settings, and analysis options from the Properties panel. Edits apply live in the viewport.

Projectors mount behind the screen and the screen is switched to back-projection.
Shows a rig truss connecting the projector row (flat and curved screens).
Verifies the generated layout with the projection-quality analysis (coverage, overlaps, illuminance) right away.
Turn off if you only want screen and projector planning.
Leave empty to auto-calculate a camera position that frames the projector array.
Sweeps projector count, model, orientation, throw distance and blend overlap, then ranks the best layouts for your surface and targets. Pin optional targets below — layouts that miss one are flagged and demoted.

Render a video of the 3D scene to share with stakeholders — plays anywhere, no viewer or login needed.
Orbit circles the scene once around the current view. The tour flies through your saved camera views (slots 1-9 and named presets) in order, pausing briefly at each one.
Preview plays the camera move live without recording. Export downloads a video file (MP4 where supported, otherwise WebM); click again to cancel. Fixed resolutions record 16:9 — the viewport can look stretched during the take, the video is correct.
