IsosurfacingDomainWithGradient_3 Concept Reference

Definition

The concept IsosurfacingDomainWithGradient_3 describes the set of requirements to be fulfilled by any class used as input data for some isosurfacing algorithms.

Refines

IsosurfacingDomain_3

This concept refines IsosurfacingDomain_3 to add a gradient() function which is used by isosurfacing domains to query the domain for the gradient of the values field at a 3D query point (not necessarily a vertex) in space.

Has models

CGAL::Isosurfacing::Dual_contouring_domain_3

Types
typedef unspecified_type	Geom_traits
