SKWarpGeometryGrid is a grid based deformation what can be applied to nodes conforming to SKWarpable protocol. It defines normalised vertex positions for source and destination where source positions are un-warped geometry and destination warped geometry. Therefore, if destination vertex positions are not equal to source, the node will look deformed. Vertex positions Here is a …
