▼NCGAL
CEnv_plane_traits_3	The traits class template `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
CEnv_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
▼CEnv_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
CSurface_3	The `Surface_3` class nested within the surface-data traits extends the `Base_traits_3::Surface_3` type with an extra data field
CXy_monotone_surface_3	The `Xy_monotone_surface_3` class nested within the surface-data traits extends the `Base_traits_3::Xy_monotone_surface_3` type with an extra data field
CEnv_triangle_traits_3	The traits class template `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
▼CEnvelope_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
CFace
CHalfedge
CVertex
CEnvelopeTraits_3	This concept defines the minimal set of geometric predicates and operations needed to compute the envelope of a set of arbitrary surfaces in \( \mathbb{R}^3\). It refines the `ArrangementXMonotoneTraits_2` concept. In addition to the `Point_2` and `X_monotone_curve_2` types and the `Has_boundary_category` category tag listed in the base concept, it also lists the `Surface_3` and `Xy_monotone_surface_3` types, which represent arbitrary surfaces and \( xy\)-monotone surfaces, respectively, and some constructions and predicates on these types. Note however, that these operations usually involve the projection of 3D objects onto the \( xy\)-plane
