Prs3d_Drawer Class Reference

A graphic attribute manager which governs how objects such as color, width, line thickness and deflection are displayed. Prs3d_Drawer is the mother class of AIS_Drawer. As such, it is its set functions which are called to modify display parameters. In the example below we can see that the AIS_Drawer is modified to set the value of the deviation coefficient using a method inherited from Prs3d_Drawer. A drawer includes an instance of the Aspect classes with particular default values. More...

Detailed Description

A graphic attribute manager which governs how objects such as color, width, line thickness and deflection are displayed. Prs3d_Drawer is the mother class of AIS_Drawer. As such, it is its set functions which are called to modify display parameters. In the example below we can see that the AIS_Drawer is modified to set the value of the deviation coefficient using a method inherited from Prs3d_Drawer. A drawer includes an instance of the Aspect classes with particular default values.

virtual

Sets the parameter anAspect for display attributes of shading.

virtual void Prs3d_Drawer::SetShadingAspectGlobal ( const Standard_Boolean  aValue)
virtual

indicates that the ShadingAspect will be apply to the whole presentation. This allows to modify the aspect without recomputing the content of the presentation.

virtual void Prs3d_Drawer::SetTextAspect ( const Handle< Prs3d_TextAspect > &  anAspect)
virtual

Sets the parameter anAspect for display attributes of text.

virtual void Prs3d_Drawer::SetTypeOfDeflection ( const Aspect_TypeOfDeflection  aTypeOfDeflection)
virtual

Sets the type of chordal deflection. This indicates whether the deflection value is absolute or relative to the size of the object.

virtual void Prs3d_Drawer::SetTypeOfHLR ( const Prs3d_TypeOfHLR  theTypeOfHLR)
virtual

Sets the type of HLR algorithm used by drawer's interactive objects.

Reimplemented in AIS_Drawer.

virtual void Prs3d_Drawer::SetUIsoAspect ( const Handle< Prs3d_IsoAspect > &  anAspect)
virtual
virtual void Prs3d_Drawer::SetUnFreeBoundaryAspect ( const Handle< Prs3d_LineAspect > &  anAspect)
virtual

Sets the parameter anAspect for the display of shared boundaries.

virtual void Prs3d_Drawer::SetUnFreeBoundaryDraw ( const Standard_Boolean  OnOff)
virtual

Sets FreeBoundaryDraw on or off by setting the parameter OnOff to true or false. By default the unfree boundaries are drawn.

virtual void Prs3d_Drawer::SetVectorAspect ( const Handle< Prs3d_LineAspect > &  anAspect)
virtual

Sets the modality anAspect for the display of vectors.

virtual void Prs3d_Drawer::SetVertexDrawMode ( const Prs3d_VertexDrawMode  theMode)
virtual

Sets the mode of visualization of vertices of a TopoDS_Shape instance. By default, only stand-alone vertices (not belonging topologically to an edge) are drawn, that corresponds to Prs3d_VDM_Standalone mode. Switching to Prs3d_VDM_Standalone mode makes all shape's vertices visible. To inherit this parameter from the global drawer instance ("the link") when it is present, Prs3d_VDM_Inherited value should be used.

Reimplemented in AIS_Drawer.

virtual void Prs3d_Drawer::SetVIsoAspect ( const Handle< Prs3d_IsoAspect > &  anAspect)
virtual

Sets the appearance of V isoparameters - anAspect.

virtual void Prs3d_Drawer::SetWireAspect ( const Handle< Prs3d_LineAspect > &  anAspect)
virtual

Sets the parameter anAspect for display of wires.

virtual void Prs3d_Drawer::SetWireDraw ( const Standard_Boolean  OnOff)
virtual

Sets WireDraw on or off by setting the parameter OnOff to true or false.

virtual Handle< Prs3d_ShadingAspect > Prs3d_Drawer::ShadingAspect ( )
virtual

Returns settings for shading aspects. These settings can be edited. The default values are:

  • Color: Quantity_NOC_YELLOW
  • Material: Graphic3d_NOM_BRASS Shading aspect is obtained through decomposition of 3d faces into triangles, each side of each triangle being a chord of the corresponding curved edge in the face. Reflection of light in each projector perspective is then calculated for each of the resultant triangular planes.

virtual Handle< Prs3d_IsoAspect > Prs3d_Drawer::UIsoAspect ( )
virtual

Defines the attributes which are used when drawing an U isoparametric curve of a face. Defines the number of U isoparametric curves to be drawn for a single face. The LineAspect for U isoparametric lines can be edited (methods SetColor, SetTypeOfLine, SetWidth, SetNumber) The default values are: COLOR : Quantity_NOC_GRAY75 TYPE OF LINE: Aspect_TOL_SOLID WIDTH : 0.5.
