Module shader_graph 

Node-based composable shader graph system.

The shader graph compiles a directed acyclic graph of nodes into GLSL fragment shader source code at runtime. Every visual effect in Proof Engine can be described as a graph of mathematical operations.

Architecture

• ShaderGraph — owns nodes and edges, validates, compiles
• ShaderNode — individual processing unit (40+ types)
• ShaderEdge — connects an output socket to an input socket
• GraphCompiler — walks the graph and emits GLSL
• GraphOptimizer — dead-node elimination, constant folding
• ShaderPreset — named, pre-built graphs for common effects
• ShaderParameter — runtime-controllable uniform (bound to MathFunction)

Quick Start

use proof_engine::render::shader_graph::{ShaderGraph, ShaderPreset};
let graph = ShaderPreset::void_protocol();
let glsl  = graph.compile().unwrap();
println!("{}", glsl.fragment_source);
