LineStyle

LineStyle is a stylized rendering system where linework, hatching, and atmospheric shifts define the form. The surface shader preserves textures while adding illustrative shading. Post-processing passes add pattern-based hatching, surface accents, outlines, and atmospheric perspective. 

Features

1. LineStyleLit shader - Customizable shading curves, shadow colors, rim lighting, specular
2. 10 shading curve presets - Cel-shading, linear, dramatic lighting variations
3. Outline - Depth/normal/color detection, dilation multi-line, distance fading
4. Hatching - Dual-layer crosshatch, 6 procedural patterns, depth-banded scaling
5. Atmosphere - Color shifts by distance, height, and directional pan
6. Accents - Shadow fills, geometry edges, topographic contours
7. Presets - Architectural, Flat Shading, Moonlight, Neon, and Poster
8. Skybox shader - Procedural gradient, sun, stars, nebula, god rays, grain
