Typedefs
using	SimplePolygonIdx = std::vector<PolyVert>
	Single polygon contour, wound CCW, with indices. First and last point are implicitly connected. Should ensure all input is ε-valid.
using	PolygonsIdx = std::vector<SimplePolygonIdx>
	Set of indexed polygons with holes. Order of contours is arbitrary. Can contain any depth of nested holes and any number of separate polygons. Should ensure all input is ε-valid.
using	SimplePolygon = std::vector<vec2>
	Single polygon contour, wound CCW. First and last point are implicitly connected. Should ensure all input is ε-valid.
using	Polygons = std::vector<SimplePolygon>
	Set of polygons with holes. Order of contours is arbitrary. Can contain any depth of nested holes and any number of separate polygons. Should ensure all input is ε-valid.

Enumerations
enum class	OpType : char { Add , Subtract , Intersect }
	Boolean operation type: Add (Union), Subtract (Difference), and Intersect.

Detailed Description

Miscellaneous data structures for interfacing with this library.

Class Documentation

struct manifold::PolyVert

Polygon vertex.

Class Members
vec2	pos	X-Y position.
int	idx	ID or index into another vertex vector.

struct manifold::Smoothness

Defines which edges to sharpen and how much for the Manifold.Smooth() constructor.

Class Members
size_t	halfedge	The halfedge index = 3 * tri + i, referring to Mesh.triVerts[tri][i].
double	smoothness	A value between 0 and 1, where 0 is sharp and 1 is the default and the curvature is interpolated between these values. The two paired halfedges can have different values while maintaining C-1 continuity (except for 0).

struct manifold::RayHit

Result of a ray cast query against a Manifold.

Class Members
uint64_t	faceID = 0	The triangle index that was hit.
double	distance = 0	The parametric distance along the ray segment in the closed interval [0, 1], where 0 is the origin and 1 is the endpoint. Hits exactly at the origin or endpoint are included.
vec3	position = vec3(0.0)	The 3D position of the hit point.
vec3	normal = vec3(0.0)	The geometric face normal at the hit.
