类
struct	eve::procgen::urban::Vec2
	Minimal 2D vector used by the urban layout algorithms (paper coordinates). 更多...
struct	eve::procgen::urban::Street
	A street decomposed from the street network graph: consecutive street edges whose included angle is larger than 135° belong to the same street. 更多...
struct	eve::procgen::urban::Parcel
	One parcel: a CCW ring of indices into UrbanLayout::corners. 更多...
struct	eve::procgen::urban::GraphEdge
	Undirected edge of the parcel corner graph. 更多...
struct	eve::procgen::urban::UrbanLayout
	Structured urban layout produced by the hierarchical co-generation (paper Section 4) plus the geometric optimization (paper Section 5). 更多...
struct	eve::procgen::urban::UrbanOptions
	All user-facing controls for the urban generator. Defaults follow the paper (λ=0.3/0.5/0.2, γ=0.75/0.25, τ=0.5, I/L-shaped access, cul-de-sac avoidance on). 更多...
struct	eve::procgen::urban::BoundaryPosition
	Where a point sits on the polygon boundary: edge edgeIndex at parameter t in [0,1]. 更多...
struct	eve::procgen::urban::BoundarySample
	A boundary sample used for field constraints / candidate seeds. 更多...

Vec2	eve::procgen::urban::perpendicular (const Vec2 &a)
	Perpendicular.
double	eve::procgen::urban::distance (const Vec2 &a, const Vec2 &b)
	Distance.
