+========================================
+Visualisation of Grid / SciDAC format density fields using VTK (visualisation toolkit). Peter Boyle, 2025.
+========================================
+
+Uses:
+
+https://vtk.org
+
+Files are, for example, those produced by
+     Grid/HMC/ComputeWilsonFlow.cc
+and
+     Grid/HMC/site_plaquette.cc
+
+========================================
+Prerequisites:
+========================================
+
+
+1) Install ffmpeg-7.0.2  (developer install, includes headers and libraries).
+   MacOS note: must install ffmpeg from source -- homebrew only installs binaries.
+
+   https://ffmpeg.org/download.html#releases
+
+
+   Note: the latest ffmpeg (7.1.1) broke software compatibility with VTK.
+
+
+2) Build and install VTK-9.4.2, with FFMEG support enabled.
+
+   This is particularly involved on MacOS, so documented here.
+
+   cd VTK-9.4.2
+   mkdir build
+   cd build
+   ccmake ..
+
+
+Using ccmake editor, set:
+
+   FFMPEG_DIR                       /usr/local      
+
+Toggle "advanced mode" (t)
+
+Set:
+   CMAKE_EXE_LINKER_FLAGS 
+CMAKE_MODULE_LINKER_FLAGS 
+CMAKE_SHARED_LINKER_FLAGS 
+each to:
+   
+   -framework Foundation -framework AudioToolbox -framework CoreAudio -liconv -lm -framework AVFoundation -framework CoreVideo -framework CoreMedia -framework CoreGraphics -framework AudioToolbox -framework OpenGL -framework OpenGL -framework VideoToolbox -framework CoreImage -framework AppKit -framework CoreFoundation -framework CoreServices -lz -lbz2 -Wl,-framework,CoreFoundation -Wl,-framework,Security -L/usr/local/lib -lavdevice -lavfilter -lavformat -lavcodec -lswresample -lswscale -lavutil
+
+   Set paths for each of

+   VTK really should make it easier to pick up the flags required for FFMPEG linkage, especially as they are very quirky on MacOS.
+
+========================================
+Aurora compilation:
+========================================
+module load ffmpeg
+download & untar: VTK-7.0.2
+mkdir build
+cd build 
+ccmake ../
+
+"t"
+Enable: VTK_MODULE_ENABLE_VTK_IOFFMPEG   YES   
+"configure" ; should "discover" the installed ffmpeg module
+
+Still need an "X" connection to make the MPEG files.
+
+
+========================================
+Grid:
+========================================
+
+3) Build and install a version of Grid
+
+4) Ensure "grid-config" is in your path.
+
+5) cd Grid/visualisation/
+   libs=`grid-config --libs`
+   ldflags=`grid-config --ldflags`
+   cxxflags=`grid-config --cxxflags`
+   cxx=`grid-config --cxx`
+
+   mkdir build
+   cd build
+
+   LDFLAGS="$ldflags $libs " cmake .. -DCMAKE_CXX_COMPILER=$cxx -DCMAKE_CXX_FLAGS=$cxxflags 
+
+   make
+   
+6) Invoke as:
+
+   FieldDensityAnimate --isosurface <float-from-0-to-5> --grid X.Y.Z.T --file1 SciDacDensityFile1 [--xlate] [--mpeg] 
+   FieldDensityAnimate --isosurface <float-from-0-to-5> --grid X.Y.Z.T --file1 SciDacDensityFile1 --file2 SciDacDensityFile2 [--xlate] [--mpeg] 
+
+==================================
+Extensions
+==================================
+
+7) Direct calling from Grid ?:
+
+   Not yet implemented, but could develop sufficient interface to write a Lattice scalar field into MPEG direct from running code.
+
+8) Example python code: FieldDensity.py . This is not interfaced to Grid.
