Projectors
Projectors are the core element of a projection scene. Each one has a position, orientation, lens configuration, light output, and resolution.
Adding a projector
- Choose Add → Add Projector.
- Select a model in the projector library, or choose Add Generic Projector for a manually configured unit.
- If you need several matching projectors, set the quantity and arrangement in Multi-Projector Options before adding the model.
- Reposition and aim the projector with the transform handles or Properties panel.
Projector properties
| Property | Description |
|---|---|
| Name / model | Label and library model |
| Position and rotation | Projector location and orientation in the scene |
| Throw ratio | Throw distance ÷ image width |
| Lens shift H / V | Horizontal and vertical image shift within the selected lens range |
| Brightness | Projector output in lumens |
| Resolution | Native pixel resolution (width × height) |
| Dimensions | Physical width, height, and depth |
| Content | Test pattern, image, video, or another available source |
| Masking / Blanking | Percentage of the source image blanked from each edge |
Library models provide their available lenses and operating ranges. A limit indicator appears when a throw-ratio or lens-shift value reaches the selected lens limit.
The projector frustum
A wireframe frustum shows the projector's throw direction and approximate image coverage. Use it while positioning and aiming the projector; use Analysis for measured coverage and brightness results.
Masking and blanking
Use projection masking to remove unwanted overshoot before analysing a setup. The mask blanks part of the projector's source image without changing its position, lens, throw ratio, or resolution.
- Select a projector.
- Open Content → Masking / Blanking in the Properties panel.
- Enter the percentage to blank from the Left, Right, Top, and Bottom edges.
- Check the preview to see the remaining active image area. The preview keeps the projector's native source aspect ratio.
- Use Reset Mask to restore all four values to
0%.
The percentages are measured relative to the full source image. For example, a Left value of 10% blanks the leftmost tenth of the image. Opposing edges cannot be increased until they remove the entire image.
Blanked pixels emit no light and contribute no coverage. The mask is visible in the 3D projection and in the Source signal preview when using View through projector. Analysis modes that calculate projected light or coverage also exclude the blanked area, so set the mask before running or re-running an analysis.
When multiple projectors are selected, the controls show the selection average. Changing a value applies that edge setting to all selected projectors.
Masking is a scene setting:
- Each projector stores its own mask in the saved project.
- Duplicating a projector copies its mask.
- Older projects without mask data load with all four edges set to
0%. - Saving a projector to your user projector library does not save its mask. Adding that library projector to another scene therefore starts with no blanking.
Duplicating and copying
- Right-click a projector → Duplicate to create an identical copy.
- Use Replace from Library in the projector properties when you want to change the model.
- Use groups and projector arrays to manage large multi-projector setups together.
Creating projector arrays
If you want to place multiple projectors at once, see Projector Arrays. That workflow covers the Multi-Projector Options panel, automatic truss generation, linear and circular layouts, spacing, radius changes, and adding or removing projectors after the array is created.
Multi-projector setups
For large rigs, start with Projector Arrays to create a linear or circular array with an automatic truss, and use Analysis to check brightness, coverage, overlap, and image detail. For an automated layout based on screen size and throw distance, try the Setup Wizard.
