Detailed Description

Represents a sequence of connected path segments (e.g., straight lines, arcs).

This class allows the construction of a path using various types of segments and supports generating discrete waypoints and visualizing the full path.

Member Function Documentation

addStraightSegment()

void Path::addStraightSegment	(	const easy3d::vec3 &	start,
		const easy3d::vec3 &	end
	)

Adds a straight line segment to the path.

Parameters

start	The 3D start point of the segment.
end	The 3D end point of the segment.

This function creates a new LineSegment instance and appends it to the internal list of path segments.

Parameters

start	Start position of the line segment in 3D space.
end	End position of the line segment in 3D space.

draw()

void Path::draw

(

easy3d::Viewer &

viewer

)

const

Renders the full path in the viewer.

Renders the entire path as a sequence of line segments in the viewer.

This method draws all path segments currently stored in the path. Each segment handles its own rendering logic (e.g., line, arc).

Parameters

viewer

Reference to the Easy3D viewer used for rendering.

This method converts the path into a set of line segments using sampled waypoints and sends the data to an Easy3D LinesDrawable for visualization.

Parameters

viewer

Reference to the Easy3D viewer instance.

generateWaypoints()

std::vector< easy3d::vec3 > Path::generateWaypoints

(

float

spacing

)

const

Generates a list of evenly spaced waypoints along the entire path.

Generates waypoints along all segments in the path.

Parameters

spacing

Distance (in world units) between consecutive waypoints.

Returns

A vector of 3D waypoints covering all segments in the path.

This method queries each segment in the path to compute evenly spaced waypoints, then aggregates them into a single list.

Parameters

spacing

Desired distance between consecutive waypoints.

Returns

A vector of 3D points representing the waypoints.
