Could you please tell me how to visualize a simple solid in Opencascade?
I looked at the documentation but it was not very helpful..
Actually I want to know,
-what projects (TK*** projects) to add to my current project?
-what header files to include?
-and a sample to code (with all the methods) to just visualize a simple solid (TopoDS_Shape)?
Thanks

I think QTOCC is a good point to begin learning: http://qtocc.sourceforge.net/. I start with a similary project but I can't find it.

You are need previous version of OCC like 6.3.
Make install and see the samples.

Dear Ata,
I think it would be useful for you to become familiar with OCCT "Visualization User's Guide".
Besides you may found good working examples in OCCT samples (for example: ImportExport sample and Viewer3d sample), which cover all questions mentioned by you.

Granted you already have modelled the solid and have it as a TopoDS_Shape, check the Make Bottle tutorial:
TopoDS_Shape mysolid = "put solid here";
// Create the OCC Viewers
TCollection_ExtendedString a3DName( "Visual3D" );
Handle(V3d_Viewer) myViewer = createViewer( "DISPLAY", a3DName.ToExtString(), "", 1000.0 );
myViewer->Init();
myViewer->SetZBufferManagment( Standard_False );
myViewer->SetDefaultViewProj( V3d_Zpos ); // Top view
Handle_AIS_InteractiveContext ic = new AIS_InteractiveContext( myViewer );
ic->SetDisplayMode( AIS_Shaded );
Handle_AIS_Shape anAIS=new AIS_Shape(aShape);
ic->SetMaterial(anAIS,Graphic3d_NOM_PEWTER);
ic->SetColor(anAIS, Quantity_NOC_BLACK);
ic->SetDisplayMode(anAIS,1,Standard_False);
//**************************************************************************************************************
in terms of header files, for any class or type you use in the code you will need to include it at the top some thing like
#include
if the class uses the Handle() macro, that is simply a short way of writing Handle_Classname
so for instance if you use Handle(V3d_Viewer) in the code then you need to add :
#include
sometimes you dont need to include the handle just the class: #include
at the top of the file.
//***************************************
in terms of the Libs, if youre using visual studio , you will need to go to the project properties and go to linker, in additional directories, add the opencascade6.3.0/ros/bin folder
and in the inputs list, just as a starter add all the files you find in the folder.
after you learn how to work with it then worry about optmizing your code.
the input list should look some thing like:
BinLPlugin.lib
BinPlugin.lib
BinXCAFPlugin.lib
FWOSPlugin.lib
gdi32.lib
glu32.lib
opengl32.lib
PTKernel.lib

change the line :
Handle_AIS_Shape anAIS=new AIS_Shape(aShape);
with:
Handle_AIS_Shape anAIS=new AIS_Shape(mysolid);

Thanks, I did all these, but still I got this error -> error C3861: 'createViewer': identifier not found
I'm using visual studio 2008
