0024002: Overall code and build procedure refactoring -- automatic
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl": - WOK-generated header files from inc and sources from drv are moved to src - CDL files removed - All packages are converted to nocdlpack

package TopTrans
|
||||
|
||||
---Purpose: This package provides algorithms to compute
|
||||
-- complex transitions. A transition is the status of
|
||||
-- geometry near the boundary of a Shape. An example
|
||||
-- is the intersection of a curve and a surface
|
||||
-- enclosing a solid , the transition tells if the
|
||||
-- parts of the curve just before and just after the
|
||||
-- intersection are inside, outside or on the
|
||||
-- boundary of the solid.
|
||||
--
|
||||
-- The difficulty with transitions arise when dealing
|
||||
-- with trimmed geometries like edges and faces. When
|
||||
-- the geometric intersections are inside the trimmed
|
||||
-- geometry the transition is usually computed by the
|
||||
-- intersection algorithms as the trimming can be
|
||||
-- safely ignored. If the intersection falls on the
|
||||
-- trimming boundaries one must consider the
|
||||
-- neighbouring entities. Consider as an example the
|
||||
-- intersection of a curve and a solid, if the
|
||||
-- intersection falls on an edge of the solid it does
|
||||
-- not falls inside the two faces adjacent to the
|
||||
-- edge, a complex transition occurs.
|
||||
--
|
||||
-- This package provides two classes :
|
||||
--
|
||||
-- * CurveTransition is used to compute complex
|
||||
-- transitions with an other curve.
|
||||
--
|
||||
-- * SurfaceTransition is used to compute complex
|
||||
-- transitions in 3D space.
|
||||
--
|
||||
-- The curves and surfaces are given by a first or
|
||||
-- second order approximation around the intersection
|
||||
-- point. For a curve, the tangent vector or the
|
||||
-- osculating circle. For a surface the normal vector
|
||||
-- or the osculating quadric.
