Package com.codename1.gpu.shaders

package com.codename1.gpu.shaders

A library of ready made shaders built on com.codename1.gpu.shader, to mix and match into a scene: water, terrain, foliage, surfaces, toon styles, effects, liquids and skies, plus ScenePresets that set the light, sky and post processing to suit.

Every factory returns an ordinary ShaderMaterial, built only from public ShaderNode calls, so each one runs on every backend and doubles as an example to copy and change. Each class names its tunable uniforms as constants; set them with ShaderMaterial.setUniform at any time, even every frame, without rebuilding anything.

void setUp(GraphicsDevice device) {
    ScenePresets.Preset look = ScenePresets.harbourDusk();
    look.apply(device);
    Mesh sea = Primitives.grid(120f, 160);
    Material water = new Material(Material.Type.PBR).setShader(Water.ocean());
    Material quay = new Material(Material.Type.PBR).setShader(Surface.concrete());
    Material crates = new Material(Material.Type.PBR).setShader(Surface.paintedMetal());

Classes

Class	Description
Foliage	Plants that move in the wind.
Fx	Effects: energy, magic, damage and sci-fi surfaces.
Liquid	Glowing and moving liquids, and the light water throws on what lies under it.
Noise	Procedural noise built from ShaderNode math, so it runs in either stage on every backend and needs no texture.
ScenePresets	Complete looks: a sun, the sky's light, fog, tone mapping, post effects and a matching Sky dome, tuned to work together.
ScenePresets.Preset	A light, environment, post chain and sky dome that belong together.
Shading	Small building blocks most surface shaders share: view dependent terms, fades, world space texture coordinates and signed distance shapes.
Sky	Sky domes: draw an inside-out sphere (Primitives.sphere(r, 24, 32, true)) around the camera with a Material.Type.UNLIT material and setFogged(false). The colour depends only on the direction from the camera, so the dome's size and position do not matter. The sun follows the scene's light.
Surface	Man made and natural surfaces for Material.Type.PBR.
Terrain	Ground.
Toon	Stylized, non photographic shading.
Water	Water surfaces.
