What problem does it solve?

Reference guide to eliminating seams and normal discontinuities in chunked terrain rendering by detailing stitching, boundary consistency, and correct normal calculation across LOD transitions.

Core Features & Use Cases

• Vertex welding rules to ensure bit-identical boundary attributes across chunks.
• Cross-boundary vertex duplication to preserve topology when edges are shared.
• Skirt technique to hide gaps at chunk boundaries and coastlines.
• Geomorphing strategies to prevent popping during LOD changes.
• Octahedral normal encoding for compact, high-quality normals.
• Unified-mesh normal computation before chunk splitting for seam-free lighting.
• Practical use cases across terrain streaming, cliff edges, and coastline transitions.
