Class VoronoiRenderer

java.lang.Object

com.arbergashi.charts.render.BaseRenderer

com.arbergashi.charts.render.specialized.VoronoiRenderer

All Implemented Interfaces:

ChartRenderer

public final class VoronoiRenderer
extends BaseRenderer

Voronoi renderer (optimized): uses a lower-resolution sampling buffer and reuses a backing image.

Performance notes:

• No new Color(...) inside the pixel loop (precomputed palette)
• No new Point(...) or repeated mapToPixel(...) calls inside tight loops
• Sampling runs in buffer space directly
