/*! \page Examplevtk Example vtk
This example demonstrates VTK visualisation driver. The code is based on
the basic/B1 example, although the geometry has been modified. The physical
example is a concerete dump, so a cuboid with a cylindrical hole removed.
VTK is a graphical pipeline (https://book.vtk.org/en/latest/VTKBook/04Chapter4.html#pipeline-design-and-implementation)
based renderer.
VTK has some visualisation commands which are not applicable to all viewers,
which currently include cutters, clippers and geometry overlays. The VTK commands
are in vtk.mac and you can explore apply different VTK only commands.
A- VISUALISATION
================
This example is really for demonstration of VTK and so the easiest way to start with
\verbatim
% G4VIS_DEFAULT_DRIVER=VtkQt ./exampleVtk
\endverbatim
or
\verbatim
% G4UI_USE_TCSH=1 G4VIS_DEFAULT_DRIVER=VtkNative ./exampleVtk
\endverbatim
The event loop for the UI can be blocked by the VtkNative window. So if input events
are captured by VTK, then the easiest way to exit from the viewer is to hit the 'q' button,
then you are returned to the shell UI. To restart interaction then issue the command
\verbatim
Idle> /vis/vtk/startInteractor
\endverbatim
B- USER INTERFACES
==================
VTK can be used in conjunction with all UI systems. If a shell UI is used event loop for the UI can be blocked
by the VtkNative window. So if input events are captured by VTK, then the easiest way to
exit from the viewer is to hit the 'q' button, then you are returned to the shell UI.
To restart interaction then issue the command
\verbatim
Idle> /vis/vtk/startInteractor
\endverbatim
C- HOW TO RUN
=============
Starting with VTK
\verbatim
% G4VIS_DEFAULT_DRIVER=VtkQt ./exampleVtk
\endverbatim
Executing VTK specific commands
\verbatim
Idle> /control/execute vtk.mac
\endverbatim
There are various pipelines and the state of the pipelines can be
displayed by issuing this command
\verbatim
/vis/vtk/printDebug
\endverbatim
Pipelines can be switched during operation. This is performed by calling
\verbatim
/vis/vtk/set/polyhedronPipeline (append/tensor/bake/separate)
\endverbatim
and then a subsequent
\verbatim
/vis/viewer/flush
\endverbatim
There is significantly different performance between these pipelines. Append, tensor
and bake are all designed for large models and high performance. Separate creates
a pipeline for each polyhedron, each pipeline will ultimately end with a draw call.
In general with modern pipelined shaders draw calls should be kept to a minimum.
For debugging the VTK viewer it is possible to place a head up display (HUD) which
gives key information on the viewer performance. The HUD is enabled by issuing
\verbatim
/vis/vtk/set/hud 1
\endverbatim

# of the B1 example when running in interactive mode
#
/vis/open Vtk
# Specify a viewer, e.g., /vis/open OGL, or allow a system choice:
/vis/open
# This chooses a graphics system (in order of priority):
# - by argument in G4VisExecutive construction.
# - by environment variable, G4VIS_DEFAULT_DRIVER.
# - by information in ~/.g4session.
# - by mode (batch/interactive) and if interactive, by your build flags.
# See "Choosing a graphics viewer" in the Application Guide for details.
# For example, with environment variable G4VIS_DEFAULT_DRIVER:
# The format is <graphics-system> [<window-size-hint>]. Set this, e.g:
# (bash) export G4VIS_DEFAULT_DRIVER=TSG
# (tcsh) setenv G4VIS_DEFAULT_DRIVER OI
# or on the command line, precede the app invocation, e.g:
# G4VIS_DEFAULT_DRIVER=Vtk ./<application-name>
# The window-size-hint can optionally be added, e.g:
# (bash) export G4VIS_DEFAULT_DRIVER="OGLSX 1000x1000-0+0"
# Other suggestions for G4VIS_DEFAULT_DRIVER (see list of registered
# graphics systems printed at the start):
# DAWNFILE: to create a .prim file suitable for viewing in DAWN.
# HepRepFile: to create a .heprep file suitable for viewing in HepRApp.
# VRML2FILE: to create a .wrl file suitable for viewing in a VRML viewer.
# "TSG_OFFSCREEN 1200x1200": to create an image file with TSG.
