Understanding Points in SeamScape

Points are the foundational anchors in SeamScape, defining precise locations and connections within your patterns. SeamScape features two primary types of points for optimal flexibility and accuracy:

Path Points

Path Points are integral to defining the geometry of a path, such as a line or curve. Modifying a Path Point directly alters the shape of its associated path.

• Line Paths: Constructed using exactly two Path Points (a start and an end point).
• Curve Paths: Formed by two or more Path Points, often incorporating handles to manage the curvature between them.

In this illustration, A0 and A1 are Path Points defining the line, while A2, A3, A4, and A5 define the curve.

Sliding Points

Sliding Points are positioned on an existing path but do not dictate its fundamental shape. Their movement is constrained to the geometry of the path they reside on.

• Ideal for marking specific locations along a path, such as notches or connection points.
• A Sliding Point can be constrained to one or two paths. When constrained to two, it dynamically marks their intersection.

Point A2 is a Sliding Point on the curve A0-A1. Observe how A2 remains attached to the curve during movement.

Point A4 is a Sliding Point constrained by both line A0-A1 and curve A2-A3, dynamically indicating their intersection.

Functional Versatility

A single point in SeamScape can fulfill multiple roles simultaneously, providing significant design flexibility:

• Serve as a Path Point for one path.
• Function as a Sliding Point on another path.
• Act as a common endpoint for several paths.

This multifaceted nature of points, when combined with constraints, allows for the creation of highly dynamic and interconnected pattern designs.
