//! Describes functions to build linear swept topologies, called prisms.
|
|
//! A prism is defined by:
|
|
//! - a basis shape, which is swept, and
|
|
//! - a sweeping direction, which is:
|
|
//! - a vector for finite prisms, or
|
|
//! - a direction for infinite or semi-infinite prisms.
|
|
//! The basis shape must not contain any solids.
|
|
//! The profile generates objects according to the following rules:
|
|
//! - Vertices generate Edges
|
|
//! - Edges generate Faces.
|
|
//! - Wires generate Shells.
|
|
//! - Faces generate Solids.
|
|
//! - Shells generate Composite Solids
|
|
//! A MakePrism object provides a framework for:
|
|
//! - defining the construction of a prism,
|
|
//! - implementing the construction algorithm, and
|
|
//! - consulting the result.
