Task:
Load the rotstrat dataset from "rotstrat/data/rotstrat_256x256x256_float32.vtk".
Generate a visualization image of the Rotstrat dataset, temperature field of a direct numerical simulation of rotating stratified turbulence, with the following visualization settings: 
1) Create volume rendering
2) Set the opacity transfer function as a step function jumping from 0 to 1 at value 0.12
3) Set the color transfer function to assign a warm red color [0.71, 0.02, 0.15] to the highest value, a cool color [0.23, 0.29, 0.75] to the lowest value, and a grey color[0.87, 0.87, 0.87] to the midrange value
4) Set the viewpoint parameters as: [800, 128, 128] to position; [0, 128, 128] to focal point; [0, 1, 0] to camera up direction
5) Volume rendering ray casting sample distance is 0.1
6) White background
7) Visualization image resolution is 1024x1024
8) Don't show color/scalar bar or coordinate axes.
Save the visualization image as "rotstrat/results/{agent_mode}/rotstrat.png".
(Optional, but must save if use paraview) Save the paraview state as "rotstrat/results/{agent_mode}/rotstrat.pvsm".
(Optional, but must save if use pvpython script) Save the python script as "rotstrat/results/{agent_mode}/rotstrat.py".
(Optional, but must save if use VTK) Save the cxx code script as "rotstrat/results/{agent_mode}/rotstrat.cxx"
Do not save any other files, and always save the visualization image.
