[Paraview] how to draw a mesh in preview

[Neil Srinivasan]

Hi I am new to Paraview

Can you help

I have data in a CSV spreadsheet. 


It contains the xyz point coordinates of a 3D shape (20,000+ nodes). 

The file also contains the triangulation coordinates in 3 separate columns for these nodes (40000 + triangulations). These create the faces of the mesh

I can work out how to plot the points, using 

Filter—Table to points. 


How do I plot the faces?
Do the 3 columns need to be turned into an array?


And how do I colour the faces or contour them by another value (called "bi" in the spreadsheet)



here is an example of the spreadsheet

nn = node number

the 3d coordinates of the points are x, y, z

and the faces of the mesh are specified by (XYZ)

I WISH TO PLOT Points (x, y, x) , draw faces (XYZ) colour by “bi"



in matlab

it would be


trisurf(Tri,X,Y,Z,C) 


where Tri = array(XYX)

X,Y,Z = (x, y, z)

c= "bi"





nn	x	y	z	X	Y	Z	uni	bi
