• Marching Cubes note
  The 1987 iso-surface extraction algorithm — how it works, what breaks, and what to reach for when it does.
• Designing Scalar Fields for Procedural Terrain note
  How to compose height, noise, caves, brushes, and materials into a scalar field that Marching Cubes can sample reliably.
• Normals for Implicit Surfaces note
  How to recover stable, smooth normals from scalar fields, finite differences, and gradients — including chunk boundaries and transformed spaces.
• Raym — Interactive Terrain Generation with Marching Cubes experiment · 2025
  A real-time interactive terrain generation and modification system built with C and Raylib, implementing the Marching Cubes algorithm for smooth voxel-based terrain.
• From Brush Stroke to Mesh — Real-Time Voxel Terrain Editing in C note
  The complete edit loop behind a sculptable Marching Cubes terrain — picking, density updates, dirty chunks, remeshing, and GPU hand-off.
• Marching Cubes on the GPU — count, scan, emit note
  A practical GPU pipeline for turning a scalar field into variable-length triangle output.
• Seamless Chunked Voxel Terrain note
  The sample ownership, halo, dirty-region, and precision rules that keep Marching Cubes chunks from growing cracks and lighting seams.
• Transvoxel in Practice note
  A table-driven guide to stitching Marching Cubes terrain across a 2:1 level-of-detail boundary without cracks.
