Class Foliage

java.lang.Object
com.codename1.gpu.shaders.Foliage
public final class Foliage extends Object
Plants that move in the wind. The sway is a vertex offset that grows with height above the model's origin, so put each plant's origin at its root. Gusts roll across the scene in world space, so neighbours move together.

    grass()
    Grass blades: a root to tip gradient along the texture's v (0 at the root), wind, and a sheen toward the sun.
    static ShaderMaterial
    leaves()
    Leaf cards: wind sway, the texture's alpha cut out, and sunlight glowing through leaves seen against the sun.
    static ShaderMaterial
    wind()
