Gen Region Module

Region-based procedural urban generation system for buildings, blocks, and road layouts.

Overview

The region module implements procedural generation of urban regions including building placement, block subdivision, road-side structures, and region boundary logic. It works with the decal road system to generate buildings along road networks with configurable dimensions and spacing.

Usage Example

local R = require('/lua/ge/extensions/editor/gen/region')

-- The region module works with the decal road system
-- to place buildings along road sides.
-- Junction medians are computed for proper corner geometry:
local dir = forMedian(sideFrom, sideTo)

-- Project a point onto a road side:
local dist = toStem(point, side, 0)  -- 0=start, 1=end

Exported Functions

R.forRoads(p, odec)

Initializes road-side building generation from a position.

• p (vec3) - Reference position
• odec (table) - Decal module reference

R.populate(acrs, adecal, odec, oworld, cancel, pt)

Populates buildings along road sides within region boundaries.

• acrs (table) - Road crossing data
• adecal (table) - Decal array
• odec (table) - Decal module
• oworld (table) - World module
• cancel (any) - Cancellation flag
• pt (vec3?) - Optional reference point

R.onUpdate(inj)

Per-frame update callback with injection data.

• inj (table?) - Optional injection data

R.onSpacing(v)

Adjusts building spacing parameter.

• v (number) - Spacing value
