static void | Add (const Handle< Prs3d_Presentation > &aPresentation, const Adaptor3d_Curve &aCurve, const Handle< Prs3d_Drawer > &aDrawer) |
Defines display of BSpline and Bezier curves. Adds the 3D curve aCurve to the StdPrs_PoleCurve algorithm. This shape is found in the presentation object aPresentation, and its display attributes are set in the attribute manager aDrawer. The curve object from Adaptor3d provides data from a Geom curve. This makes it possible to use the surface in a geometric algorithm. More... | |
static Standard_Boolean | Match (const Quantity_Length X, const Quantity_Length Y, const Quantity_Length Z, const Quantity_Length aDistance, const Adaptor3d_Curve &aCurve, const Handle< Prs3d_Drawer > &aDrawer) |
returns true if the distance between the point (X,Y,Z) and the broken line made of the poles is less then aDistance. More... | |
static Standard_Integer | Pick (const Quantity_Length X, const Quantity_Length Y, const Quantity_Length Z, const Quantity_Length aDistance, const Adaptor3d_Curve &aCurve, const Handle< Prs3d_Drawer > &aDrawer) |
returns the pole the most near of the point (X,Y,Z) and returns its range. The distance between the pole and (X,Y,Z) must be less then aDistance. If no pole corresponds, 0 is returned. More... | |
![]() | |
static Handle< Graphic3d_Group > | CurrentGroup (const Handle< Prs3d_Presentation > &thePrs3d) |
Returns the current (last created) group of primititves inside graphic objects in the display. A group also contains the attributes whose ranges are limited to the primitives in it. More... | |
static Handle< Graphic3d_Group > | NewGroup (const Handle< Prs3d_Presentation > &thePrs3d) |
Returns the new group of primitives inside graphic objects in the display. A group also contains the attributes whose ranges are limited to the primitives in it. More... | |
