The types of shapes that can be used for an overlay include:
- SVG Paths: These can be used to create complex interaction regions, as mentioned in the context of visionOS. SVG paths allow for fine-grained control over the shapes used in overlays.
- Circles: Circles can be defined as SwiftUI paths and used in various contexts, such as defining the shape and color of a brush in a spatial drawing app.
- Bezier Curves: These can be used to create flexible shapes, such as logo marks, which can be defined using SwiftUI paths.
