Detailed Description
Describes functions to build evolved shapes. An evolved shape is built from a planar spine (face or wire) and a profile (wire). The evolved shape is the unlooped sweep (pipe) of the profile along the spine. Self-intersections are removed. A MakeEvolved object provides a framework for:
- defining the construction of an evolved shape,
- implementing the construction algorithm, and
- consulting the result. Computes an Evolved by 1 - sweeping a profile along a spine. 2 - removing the self-intersections.
The Profile is expected to be planar and can be a line (which lies in infinite number of planes).
The profile is defined in a Referential R. The position of the profile at the current point of the spine is given by confusing R and the local referential given by ( D0, D1 and the normal of the Spine).
The coordinate system is determined by theIsAxeProf argument:
- if theIsAxeProf is true, R is the global coordinate system,
- if theIsAxeProf is false, R is computed so that:
- its origin is given by the point on the spine which is closest to the profile,
- its "X Axis" is given by the tangent to the spine at this point, and
- its "Z Axis" is the normal to the plane which contains the spine.
theJoinType defines the type of pipe generated by the salient vertices of the spine. The default type is GeomAbs_Arc where the vertices generate revolved pipes about the axis passing along the vertex and the normal to the plane of the spine. At present, this is the only construction type implemented.
if <theIsSolid> is TRUE the Shape result is completed to be a solid or a compound of solids.
If theIsProfOnSpine == TRUE then the profile must connect with the spine.
If theIsVolume option is switched on then self-intersections in the result of Pipe-algorithm will be removed by BOPAlgo_MakerVolume algorithm. At that the arguments "theJoinType", "theIsAxeProf", "theIsProfOnSpine" are not used.
