Edit Rectangle
When the grid is in Edit Rectangle mode, the onscreen controls display a rectangle that
determines the dimensions of the grid. The sides of the rectangle can be adjusted to increase
or decrease the grid’s dimension. This mode also reveals the onscreen Center control
for the grid.
Edit Line
The Edit Line mode is beneficial for creating grids around organic shapes. When this mode is
enabled, all onscreen controls disappear, and a spline can be drawn around the shape or
object to be deformed. While drawing the spline, a grid is automatically created that best
represents that object. Additional controls for Tolerance, Over Size, and Snap Distance appear
when this mode is enabled. These controls are documented below.
Set Mesh to Entire Image
The Set Mesh to Entire Image button automatically resets the size of the grid to the exact
dimensions of the image. Any adjustments to vertices within the grid are reset.
Copy Buttons
These two buttons provide a technique for copying the exact shape and dimensions of the
source grid to the destination, or the destination grid to the source. This is particularly useful
after setting the source grid to ensure that the destination grid’s initial state matches the source
grid before beginning a deformation.
Point Tolerance
This control is visible only when the Edit Line mode is enabled. The Point Tolerance slider
determines how much tessellation the grid applies to match the density of points in the spline
closely. The lower this value, the fewer vertices there are in the resulting grid, and the more
uniform the grid appears. Higher values start applying denser grids with variations to account
for regions in the spline that require more detail.
Oversize Amount
This control is visible only when the Edit Line mode is enabled. The Oversize Amount slider is
used to set how large an area around the spline should be included in the grid. Higher values
create a larger border, which can be useful when blending a deformation back into the
source image.
Snap Distance
This control is visible only when the Edit Line mode is enabled. The Snap Distance slider
dictates how strongly the drawn spline attracts surrounding vertices. If a vertex is close enough
to a spline’s edge, the vertex moves to line up with the spline. The higher the value, the farther
the reach of the spline.
Right-Click Here for Mesh Animation
The grids are static by default. Right-clicking on the Right-Click Here for Mesh Animation label
provides a contextual menu with options for animating the grid or connecting it to another grid
in the composition.
The grid uses a Polychange spline. Any adjustment to the control points adds or modifies the
keyframe for all points on that spline.
Right-Click Here for Shape Animation
This label appears only in the Edit Line mode. Right-clicking on the Right-Click Here for Shape
Animation label reveals a pop-up menu used to animate the shaping polyline or to connect it to
other polylines.
