Press F7 to toggle adaptive mesh resolution.Press F6 to increase the mesh resolution.Press F5 to decrease the mesh resolution.Press F4 to increase the number of vertical control points.Press F3 to reduce the number of vertical control points.Press F2 to increase the number of horizontal control points.Press F1 to reduce the number of horizontal control points.Press R to reset the warp to its default settings.Use mouse or cursor keys to move the currently selected control point.When activated using the Warp::enableEditMode(true) function, these are the keys you can use: The addon provides a built-in editor to adjust your warps. This addon supports HSB adjustments as well as the assignment of a color LUT texture. Proper blending may also require color calibration between physical projectors. Blending can be accomplished with this addon through the edge blending functions or by assigning a blend LUT texture. Projection blending is the process of creating a single image from multiple virtual or physical projections. If you (accidentally) move your projector later, all you need to do is adjust the four corners and the projection should perfectly fit on the curved wall again. Perspective-bilinear warp: a combination of both techniques, where you first drag the four corners of your content to the desired location on the wall, then adjust for curvatures using the additional control points.
Simply add control points to the warp and drag them to where you want your content to be. Bilinear warp: inferior to perspective warping on flat surfaces, but allows projecting onto curved surfaces.Then simply drag the four corners of your content where you want them to be on the wall. For best results, disable any keystone correction on the projector. Use it to exactly project your content on a rectangular area on a wall or building, regardless of how your projector is setup.
Perspective warp: performs image correction for projecting onto flat surfaces in case the projector is not horizontally and/or vertically aligned with the wall.There are three types of warps available: Projection warping is the process of manipulating an image so that it can be projected onto flat or curved surfaces without distortion. This is extended port of the Cinder-Warping block by Paul Houx.
