Package com.codename1.gpu.shader

package com.codename1.gpu.shader

Portable custom shading for com.codename1.gpu.

A ShaderNode is one value of a shader -- a constant, an input such as the world position or the time, a texture sample, or math on other nodes. A ShaderMaterial attaches graphs of them to hooks of the engine's own shader (VERTEX_OFFSET, BASE_COLOR, NORMAL, METALLIC, ROUGHNESS, EMISSIVE, DISCARD), so custom surfaces are still lit, shadowed and fogged. Every backend prints the same graph in its own language through ShaderEmitter: GLSL on Android, the browser, the simulator and Linux, Metal on Apple platforms and HLSL on Windows.
