6.3 Content preview

Switch to Content and each projector projects an image instead of a colour. With no image loaded you get a test card whose corner markers land exactly on the frustum corners, so keystone stretch is visible directly.

Content preview showing two overlapping test cards — Figure 6.3 Content preview on the blended pair. Both test cards are visible, and the region where they overlap is brighter and doubled — which is what an un-blended overlap looks like in the room.

Load image… replaces the test card with your own still. The image is stored by content hash rather than inside the project, so a large still does not get re-uploaded every time you nudge a projector.
