14 VP-790 Warp Generator - Preparing a Grid

5 Preparing a Grid

To prepare a grid do the following:

• Edit an existing grid file or start a new grid

• Use the Grid Designer PRESETS for initial settings

• Use Grid Designer and Grid Editor to finalize the warp map

• Upload it to the VP-790 (see

Section 5.4

The following example shows a projector positioned above a convex shaped screen

and directed at the screen center, as illustrated in

)

Figure 13:

Figure 13: Projector Setup for Convex Screen

The blue projection image field is naturally keystoned when such a projector

alignment is used within an installation, so Warp Generator must compensate for

both the keystone effect and also the curvature of the screen. To do this, the Preset

Menu, the 3x3 Curvature controls and the Point Edit Control functions will be

used.
