Module shaders 

Built-in shader sources for the Khora Engine rendering system.

This module provides compile-time embedded shader source code for the core rendering strategies. These shaders are part of the “Strategies” layer in the SAA/CLAD architecture, representing the GPU execution paths for various render lanes.

Available Shaders

• LIT_FORWARD_WGSL - Multi-light forward rendering with Blinn-Phong lighting
• STANDARD_PBR_WGSL - Physically-based rendering with metallic-roughness workflow
• UNLIT_WGSL - Simple unlit rendering with vertex colors
• EMISSIVE_WGSL - Self-illuminating materials
• WIREFRAME_WGSL - Debug wireframe visualization

Usage

use khora_lanes::shaders::LIT_FORWARD_WGSL;
use khora_core::renderer::{ShaderModuleDescriptor, ShaderSourceData};
use std::borrow::Cow;

let descriptor = ShaderModuleDescriptor {
    label: Some("lit_forward"),
    source: ShaderSourceData::Wgsl(Cow::Borrowed(LIT_FORWARD_WGSL)),
};
