Class GradientFiller

java.lang.Object

io.github.shimeoki.jfx.rasterization.triangle.GradientFiller

All Implemented Interfaces:

Filler

public final class GradientFiller
extends Object
implements Filler

One of the standard implementations of Filler to fill the triangles with a gradient from three colors.

Linearly interpolates the color based on the barycentric coordinates. The colors are numbered and mapped to the corresponding numbered coordinates of the barycentrics.

Since:

2.0.0
