A framework to manage presentation and selection of shapes. AIS_Shape is the interactive object which is used the most by applications. There are standard functions available which allow you to prepare selection operations on the constituent elements of shapes - vertices, edges, faces etc - in an open local context. The selection modes specific to "Shape" type objects are referred to as Standard Activation Mode. These modes are only taken into account in open local context and only act on Interactive Objects which have redefined the virtual method AcceptShapeDecomposition so that it returns true. Several advanced functions are also available. These include functions to manage deviation angle and deviation coefficient - both HLR and non-HLR - of an inheriting shape class. These services allow you to select one type of shape interactive object for higher precision drawing. When you do this, the Prs3d_Drawer::IsOwn... functions corresponding to the above deviation angle and coefficient functions return true indicating that there is a local setting available for the specific object.

Detailed Description

A framework to manage presentation and selection of shapes. AIS_Shape is the interactive object which is used the most by applications. There are standard functions available which allow you to prepare selection operations on the constituent elements of shapes - vertices, edges, faces etc - in an open local context. The selection modes specific to "Shape" type objects are referred to as Standard Activation Mode. These modes are only taken into account in open local context and only act on Interactive Objects which have redefined the virtual method AcceptShapeDecomposition so that it returns true. Several advanced functions are also available. These include functions to manage deviation angle and deviation coefficient - both HLR and non-HLR - of an inheriting shape class. These services allow you to select one type of shape interactive object for higher precision drawing. When you do this, the Prs3d_Drawer::IsOwn... functions corresponding to the above deviation angle and coefficient functions return true indicating that there is a local setting available for the specific object.

This class allows to map textures on shapes using native UV parametric space of underlying surface of each Face (this means that texture will be visually duplicated on all Faces). To generate texture coordinates, appropriate shading attribute should be set before computing presentation in AIS_Shaded display mode:

Handle(AIS_Shape) aPrs = new AIS_Shape();
aPrs->Attributes()->SetupOwnShadingAspect();
aPrs->Attributes()->ShadingAspect()->Aspect()->SetTextureMapOn();
aPrs->Attributes()->ShadingAspect()->Aspect()->SetTextureMap (new Graphic3d_Texture2Dmanual (Graphic3d_NOT_2D_ALUMINUM));

The texture itself is parametrized in (0,1)x(0,1).
