Distort effects
Zaxwerks provides a set of 3D Warps effect plug-ins, which can be used to distort layers in 3D space:
.
Bezier Warp effect
The Bezier Warp effect shapes an image using a closed Bezier curve along the boundary of a layer. The curve consists
of four segments. Each segment has three points (a vertex and two tangents).
This effect works with 8-bpc and 16-bpc color.
Original (top left) and with variations of Bezier Warp applied (bottom left and right)
The positions of the vertices and tangents determine the size and shape of a curved segment. Dragging these points
reshapes the curves that form the edge, thus distorting the image. For example, you can use Bezier Warp to reshape
one image to fit another, as in wrapping a label around a jar. Bezier Warp is also useful for correcting lens aberrations,
such as the fisheye effect (barrel distortion) that can occur with a wide-angle lens; using Bezier Warp, you can bend
the image back to achieve an undistorted look. By animating the effect and choosing a high quality setting, you can
create fluid visual effects, such as a jiggling gelatin dessert or a fluttering flag.
Bulge effect
The Bulge effect distorts an image around a specified point, making the image appear to bulge toward or away from
the viewer, depending on the options you select.
This effect works with 8-bpc and 16-bpc color.
