Terrain Generation Deep Dive Part 2: Base Shapes and Macro Features

Macro structure before micro detail

The terrain pipeline begins with large-scale composition. We define the strategic skeleton first: where the high ground sits, where valleys run, and where conflict lanes are expected to form.

This avoids a common procedural trap where local noise dominates and the map loses strategic identity.

• Base plate generation establishes broad elevation intent.
• Basin, valley, and choke stages shape route logic early.
• Mask builders control how each stage contributes to the final field.

SDF-style composition and controllable blending

SDF-inspired composition allows macro forms to combine smoothly while keeping strong control over transitions. Instead of hard seams, we blend and carve in a predictable way.

This supports features like canyons, terraces, and route corridors without introducing random topological failures.

• Distance-based blending gives clean transitions between features.
• Carve stages can target local zones without rewriting global structure.
• Detail layers are added after core topology is stable.

Parameter discipline

A robust map stack is parameterized, but not unrestricted. We expose controls that matter for design while constraining combinations that cause degenerate maps.

That means each stage can be tuned independently while still respecting the overall strategic profile of the map.

• Safe defaults keep outputs reliable for quick iteration.
• Feature flags and stage tuning are documented for repeatability.
• Per-stage diagnostics make parameter effects visible.
