Very Fast Task Using Paraview -- 2
Budget: €8 – €30 EUR
Create the indicated views with Paraview, insert the indicated snapshots into a text document (word, libreoffice, pdf...), briefly commenting and deliver the document together with the video and the status file in .py format.

1.Create a slice that cuts the volume with a slice perpendicular to the y axis and arrange the camera so as to frame the slices clearly and visualize the "scalars" data on the slice with a perceptually linear colormap, mapped on the range 100 -300.
You create an animation in which a piano slides across the volume and shows different sections continuously. At the initial and final frame the plane must already/still be inside the volume and the slice must be visible. A 3 second video is saved with a frame rate of 20 frames/second.
Hide the result and do the next part.
2.Create an isosurface on the original volume that represents the edge of the vessels at value 200 of the "scalars" variable, coloring it blue. The rendering is modified by introducing the specular component (coefficient 0.8) and an environmental component equal to 0.1.
Create a second Render View in which the blood vessels are displayed with volumetric rendering of the "scalars" variable, using a transfer function that makes "scalars" values less than 180 transparent, only those between 180 and 250 very opaque with color blue. Volumetric shading is enabled. Connect the "camera views" of the two windows to have the same shot. Frame the entire volume and save a snapshot of both to insert into the text document.
Hide the results and do the next part.
3.Extract from the volume the points with velocity magnitude values between 1 and 10. Display the histogram of the modulus (magnitude) values of the vector field in the selection, reducing the number of bins in the histogram to 32. Insert legends on the axes. Save the histogram snapshot to insert into your document. Hide the results and do the next part.
If you take the selection and display these arrow points, directly as vectors, with length proportional to the module and colored according to the module with colormap of your choice. Try to find a scale of arrows and a sampling that make the visualization effective based on what was discussed in class. Save a snapshot to insert into your document. Justify your choices in the document where you paste it.
Hide the results and do the next part.
4.Selecting the entire volume again, create streamlines that illustrate the "vector" variable, sampling the seeds of the streamlines with source sphere, centered at the point where the value of the "scalar" field is maximum, using radius 6, applying the filter that approximates the lines with tubes of reasonable diameter for display and coloring based on the module of the vorticity variable calculated by the filter (check that the flag that enables the calculation is selected). Save a snapshot and insert it into your document.
