Struct PatchDef 

pub struct PatchDef {
    pub sides: [Option<PatchSide>; 4],
}

A patch of the network: its four sides, walked round it.

Side 0 runs along u at v = 0, side 1 up v at u = 1, side 2 back along u at v = 1, side 3 back down v at u = 0, so the walk turns counter-clockwise seen from the side the patch’s normal S_u × S_v faces. Two patches sharing a curve walk it in opposite directions, as the faces of a shell do. One side may be missing: a three-sided patch, that side shrunk to the point where its neighbours meet.

Fields

sides: [Option<PatchSide>; 4]

The sides, in walking order.

Implementations

impl PatchDef

pub fn four(sides: [(usize, bool); 4]) -> Self
