37 | //! Describes functions to build evolved shapes. |
38 | //! An evolved shape is built from a planar spine (face or |
39 | //! wire) and a profile (wire). The evolved shape is the |
40 | //! unlooped sweep (pipe) of the profile along the spine. |
41 | //! Self-intersections are removed. |
42 | //! A MakeEvolved object provides a framework for: |
43 | //! - defining the construction of an evolved shape, |
44 | //! - implementing the construction algorithm, and |
45 | //! - consulting the result. |
46 | //! Computes an Evolved by |
85843588 |
47 | //! 1 - sweeping a profile along a spine. |
42cf5bc1 |
48 | //! 2 - removing the self-intersections. |
49 | //! |
85843588 |
50 | //! The Profile is expected to be planar and can be a line |
51 | //! (which lies in infinite number of planes). |
52 | //! |
42cf5bc1 |
53 | //! The profile is defined in a Referential R. The position of |
54 | //! the profile at the current point of the spine is given by |
55 | //! confusing R and the local referential given by ( D0, D1 |
85843588 |
56 | //! and the normal of the Spine). |
42cf5bc1 |
57 | //! |
85843588 |
58 | //! The coordinate system is determined by theIsAxeProf argument: |
59 | //! - if theIsAxeProf is true, R is the global coordinate system, |
60 | //! - if theIsAxeProf is false, R is computed so that: |
61 | //! * its origin is given by the point on the spine which is |
62 | //! closest to the profile, |
63 | //! * its "X Axis" is given by the tangent to the spine at this point, and |
64 | //! * its "Z Axis" is the normal to the plane which contains the spine. |
42cf5bc1 |
65 | //! |
85843588 |
66 | //! theJoinType defines the type of pipe generated by the salient |
67 | //! vertices of the spine. The default type is GeomAbs_Arc |
68 | //! where the vertices generate revolved pipes about the |
69 | //! axis passing along the vertex and the normal to the |
70 | //! plane of the spine. At present, this is the only |
71 | //! construction type implemented. |
72 | //! |
73 | //! if <theIsSolid> is TRUE the Shape result is completed to be a |
42cf5bc1 |
74 | //! solid or a compound of solids. |
85843588 |
75 | //! |
76 | //! If theIsProfOnSpine == TRUE then the profile must connect with the spine. |
77 | //! |
78 | //! If theIsVolume option is switched on then self-intersections |
79 | //! in the result of Pipe-algorithm will be removed by |
80 | //! BOPAlgo_MakerVolume algorithm. At that the arguments |
81 | //! "theJoinType", "theIsAxeProf", "theIsProfOnSpine" are not used. |
