The 3D view class.

This package was originally written by Evgueni Tcherniaev from IHEP/Protvino.

The original Fortran implementation was adapted to HIGZ/PAW by Olivier Couet and Evgueni Tcherniaev.

This View class is a subset of the original system. It has been converted to a C++ class by Rene Brun.

TView3D creates a 3-D view in the current pad. In this 3D view Lego and Surface plots can be drawn and also 3D polyline and markers. Most of the time a TView3D is created automatically when a 3D object needs to be painted in a pad (for instance a Lego or a Surface plot).

In some case a TView3D should be explicitly. For instance to paint a 3D simple scene composed of simple objects like polylines and polymarkers. The following macro gives an example:

{
   auto cV3D = new TCanvas("cV3D","PolyLine3D & PolyMarker3D Window",200,10,500,500);
 
   // Creating a view
   TView3D *view = (TView3D*) TView::CreateView(1);
   view->SetRange(5,5,5,25,25,25);
 
   // Create a first PolyLine3D
   TPolyLine3D *pl3d1 = new TPolyLine3D(6);
   pl3d1->SetPoint(0, 10, 20, 10);
   pl3d1->SetPoint(1, 15, 15, 15);
   pl3d1->SetPoint(2, 20, 20, 20);
   pl3d1->SetPoint(3, 20, 10, 20);
   pl3d1->SetPoint(4, 10, 10, 20);
   pl3d1->SetPoint(5, 10, 10, 10);
 
   // Create a first PolyMarker3D
   TPolyMarker3D *pm3d1 = new TPolyMarker3D(9);
   pm3d1->SetPoint( 0, 10, 10, 10);
   pm3d1->SetPoint( 1, 20, 20, 20);
   pm3d1->SetPoint( 2, 10, 20, 20);
   pm3d1->SetPoint( 3, 10, 10, 20);
   pm3d1->SetPoint( 4, 20, 20, 10);
   pm3d1->SetPoint( 5, 20, 10, 10);
   pm3d1->SetPoint( 6, 20, 10, 20);
   pm3d1->SetPoint( 7, 10, 20, 10);
   pm3d1->SetPoint( 8, 15, 15, 15);
   pm3d1->SetMarkerSize(2);
   pm3d1->SetMarkerColor(4);
   pm3d1->SetMarkerStyle(2);
 
   // Draw
   pl3d1->Draw();
   pm3d1->Draw();
}

Several coordinate systems are available:

Cartesian
Polar
Cylindrical
Spherical

kOnlyPrepStep

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer.

This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

Member Function Documentation

◆ AbstractMethod()

void TObject::AbstractMethod ( const char * method ) const

inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning: This interface is a legacy function that is no longer recommended to be used by new development code.

Note: The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

◆ CheckedHash()

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.

(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

virtualinherited

Return hash value for this object.

call RecursiveRemove for obj if gROOT is valid and obj.TestBit(kMustCleanup) is true.

Definition TROOT.h:406

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

◆ HasInconsistentHash()

Bool_t TObject::HasInconsistentHash ( ) const

inlineinherited

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.

missing call to RecursiveRemove in destructor).

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

◆ SaveAs()

void TObject::SaveAs	(	const char *	filename = "",
		Option_t *	option = "" ) const

virtualinherited

Save this object in the file specified by filename.

if "filename" contains ".root" the object is saved in filename as root binary file.
if "filename" contains ".xml" the object is saved in filename as a xml ascii file.
if "filename" contains ".cc" the object is saved in filename as C code independent from ROOT. The code is generated via SavePrimitive(). Specific code should be implemented in each object to handle this option. Like in TF1::SavePrimitive().
otherwise the object is written to filename as a CINT/C++ script. The C++ code to rebuild this object is generated via SavePrimitive(). The "option" parameter is passed to SavePrimitive. By default it is an empty string. It can be used to specify the Draw option in the code generated by SavePrimitive.

The function is available via the object context menu.

◆ Write() [2/2]

Int_t TObject::Write	(	const char *	name = nullptr,
		Int_t	option = 0,
		Int_t	bufsize = 0 ) const

virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
The TBuffer object is filled via the class::Streamer function.
If the file is compressed (default) a second buffer is created to hold the compressed buffer.
Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.

Reimplemented in TSQLFile, TXMLFile, TDirectory, TBuffer, TDirectoryFile, TFile, TParallelMergingFile, TCollection, TMap, and TTree.
