Light Quake Visualizer

A collection of scripts to visualize SeisSol output using PyVista.

Features

• Visualize SeisSol output files in XDMF and HDF-VTK formats
• Support for multiple datasets and variables
• Customizable color maps, color ranges, and scalar bar settings, lighting
• Slicing options
• And more...

For more information on available options and their descriptions, run:

A simple example of use

Plot the volume output file at time 10s, variable u with a pvcc (saved from ParaView):

light_quake_visualizer output_tpv5_ref/tpv5_sym.xdmf --var u --time 10.0 --cmap broc --view output_tpv5_ref/tpv5.pvcc  --scalar_bar "0.9 0.1" --color_range "-0.5 0.5" --zoom 1.0 --lighting 0.6 0.4 0.6

Plotting several datasets

Here sliced volume output (variable u), and (unsliced) fault output (variable ASl):

light_quake_visualizer  "output_tpv5_ref/tpv5_sym.xdmf;output_tpv5_ref/tpv5_sym-fault.xdmf" --var "u;ASl" --time 10.0 --cmap "broc;viridis" --view output_tpv5_ref/tpv5.pvcc  --scalar_bar "0.8 0.1" --color_range "-0.5 0.5;0 5" --zoom 1.0 --light 0.5 0.5 0.5 --slice "0 0 -2000 0 0 1" "1;0"

Support for the new HDF-VTK

Example usage with the new HDF-VTK format:

light_quake_visualizer  output_tpv5_new_format/tpv5_sym-wavefield-2.hdf --var u --time "i0" --cmap broc --view output_tpv5_ref/tpv5.pvcc  --scalar_bar "0.9 0.1" --color_range "-0.5 0.5" --zoom 1.0 --lighting 0.6 0.4 0.6

Generate vector graphic color bar image

Example usage:

generate_color_bar vik --crange -2 2 --labelfont 8 --height 1.2 3.6 --nticks 3

Combining snapshots with possible overlap

Change the background to white, and combine several images with partial overlap:

image_combiner --i image1.png image2.png --o combined_image.png --col 2 --rel 0.5 1.0
