Detailed Description

Provides a static utility function to create a smooth QPainterPath from blob control points.

This class is used to generate the visual outline of the blob by creating a closed curve that interpolates smoothly through the given control points.

Member Function Documentation

CreateBlobPath()

QPainterPath BlobPath::CreateBlobPath ( const std::vector< QPointF > & control_points, int num_of_points )

static

Creates a closed, smooth QPainterPath using Catmull-Rom-like spline interpolation.

Iterates through the provided control points and generates cubic Bezier segments to create a smooth, closed curve passing through them. Uses neighboring points to calculate control handles for the Bézier curves, effectively creating a Catmull-Rom spline effect with a specified tension. Includes validation to skip invalid points.

Parameters

control_points	A vector containing the QPointF coordinates of the blob's control points.
num_of_points	The number of control points in the vector. Should match control_points.size().

Returns

A QPainterPath representing the smooth outline of the blob. Returns an empty path if control_points are empty.
