Warping Outputs

In cases where the projection surface does not match the virtual 3D model (i.e. where the lineup from the manual or automatic calibration needs a slight fine-tune), Designer provides a number of powerful warping layers that can be applied directly to the output. By using these tools, there is no requirement for projector keystoning or any other warping inside the physical projector.

Warning

If you’re considering warping due to poor calibration, double-check that no warps were active on the projector during calibration, as this can affect the results. Also, consider whether warping is necessary for your setup.

Adding and Using Warping Layers

To add a warping layer to an output:

1. Left-click Feed in the dashboard at the top of the screen.
2. Right-click the relevant output.
3. Select Edit Warp from the context menu options list.

For more information on the dashboard layout and functionality, refer to the Designer User Interface section.

Deformation Layers for Warping an Output Feed

In the editing window, left-click the + button under the Deformation layers title.

This will display a list of deformation layers.

Tip

Warp points can be added to the output so you can see exactly which part of the output is being manipulated.

Warping Layer Types

4point

Drag any of the 4 points inwards to globally adjust the warping of the output. Adjust the horizontal and vertical bias to shift-scale the content.

9point

9point warp allows you to drag 9 points inwards and adjust the pinch and straightness between them. This feed warp is useful when projecting onto a cylindrical screen when not using Projector Simulation. It easily conforms a rectangular output to fit to a cylindrical screen.

Custom

Creates an arbitrary number of grid points on the output that can be individually or group-selected. You can use this when local warping on an object is required.

Grid

Provides a regular grid of points for more structured and uniform warping adjustments across the output

Reference other projector

Uses the deformation of another projector as a reference to synchronise output warping across multiple devices.

Circular

Applies circular deformation for radial-based warping needs, useful for dome or spherical projections.

Lens Deform

Simulates lens distortion effects, allowing correction or emulation of barrel or pincushion distortion.

Draw control points on output

Visually place and adjust control points directly on the output for precise manipulation.
