Projectors
Projectors are the core element of every scene. Each projector has a position, orientation, lens configuration, and a full set of photometric specifications.
Adding a projector
- Click Add Projector in the toolbar or scene panel.
- In the Model dropdown, search the built-in library (130+ models from Panasonic, Christie, Barco, Epson, and others) or choose Custom to enter specifications manually.
- The projector is placed at the origin. Reposition it using the 3D handles or the properties panel.
Projector properties
Position
X, Y, Z coordinates in metres (world space).
Rotation
| Property | Description |
|---|---|
| Pitch | Tilt up/down (degrees) |
| Yaw | Pan left/right (degrees) |
| Roll | Rotate around throw axis (degrees) |
Lens
| Property | Description |
|---|---|
| Throw ratio | Throw distance ÷ image width |
| Focal length | Lens focal length in mm |
| Zoom | Optional zoom factor (for zoom lenses) |
| Lens shift H / V | Horizontal and vertical lens shift as a fraction of image size |
Specifications
| Property | Description |
|---|---|
| Brightness | Output in ANSI lumens |
| Resolution | Native pixel resolution (width × height) |
| Contrast | Contrast ratio |
| Weight | Physical weight in kg |
NDI (optional)
Enable NDI to stream a live video source from the network onto the projector's throw in the 3D viewport. Enter the NDI source name and channel.
The projector frustum
A wireframe frustum visualises the throw angle and image coverage. The frustum colour indicates:
- White — default, no analysis active
- Black → Red → Yellow → White gradient — illuminance heatmap when analysis mode is on
- Orange outline — projector is selected
Duplicating and copying
- Right-click a projector → Duplicate to create an identical copy.
- Right-click → Copy Properties to paste lens and spec settings onto another projector.
- 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 Photometric Analysis for per-pixel brightness and overlap evaluation. For an automated layout based on screen size and throw distance, try the Setup Wizard.
