Detailed Description

HALF-PLANE level-set domain: ls(x, y) = a*x + b*y - c, ACTIVE on the side a*x + b*y < c.

The simplest NON-disc instance of the contract; it proves the embedded-boundary machinery is generic over an arbitrary device-safe level set, not the circle alone. POD, device-clean (three doubles).

Member Function Documentation

◆ cell_active()

POPS_HD bool pops::detail::HalfPlaneDomain::cell_active ( Real  x, Real  y  ) const

inline

ACTIVE cell: its center (x, y) is on the active side (ls < 0).

Here is the call graph for this function:

◆ level_set()

POPS_HD Real pops::detail::HalfPlaneDomain::level_set ( Real  x, Real  y  ) const

inline

Level set ls(x, y) = a*x + b*y - c: < 0 inside (active side), 0 on the line, > 0 outside.

Here is the caller graph for this function:

◆ operator()()

POPS_HD Real pops::detail::HalfPlaneDomain::operator() ( Real  x, Real  y  ) const

inline

Callable form (forwards to level_set), so the domain is directly usable as a LevelSet argument.

Here is the call graph for this function:
