## Classes
class | Env_plane_traits_3
| The traits class `Env_plane_traits_3` models the `EnvelopeTraits_3` concept, and is used for the construction of lower and upper envelopes of planes and half planes in the space. More...
class | Env_sphere_traits_3
| The traits class `Env_sphere_traits_3` models the `EnvelopeTraits_3` concept, and is used for the construction of lower and upper envelopes of spheres. More...
class | Env_surface_data_traits_3
| The class `Env_surface_data_traits_3` is a model of the `EnvelopeTraits_3` concept and serves as a decorator class that allows the extension of the surfaces defined by the base traits-class (the `Traits` parameter), which serves as a geometric traits-class (a model of the `EnvelopeTraits_3` concept), with extraneous (non-geometric) data fields. More...
class | Env_triangle_traits_3
| The traits class `Env_triangle_traits_3` models the `EnvelopeTraits_3` concept, and is used for the construction of lower and upper envelopes of triangles in the space. More...
class | Envelope_diagram_2
| The class-template `Envelope_diagram_2` represents the minimization diagram that corresponds to the lower envelope of a set of curves, or the maximization diagram that corresponds to their upper envelope. More...
