polyline_colored()

MAYAFLUX_API std::vector< Kakshya::LineVertex > MayaFlux::Kinesis::polyline_colored	(	std::span< const glm::vec2 >	pts,
		std::span< const glm::vec3 >	colors,
		float	thickness = 1.F
	)

Polyline with per-vertex colors as a LINE_LIST.

pts and colors must have equal length. Each line segment blends from the color at its start vertex to the color at its end vertex.

Parameters

pts	Ordered path vertices in NDC.
colors	Per-vertex colors. Must match pts in size.
thickness	Line thickness applied uniformly.
