# Recreating this 3D density plot in ParaView

I want to do somethings similar to the plot found at the bottom of this blogpost, which I found via this post in ParaView, which seems to have been the original Application used to generate the plot.

I have a .csv-file containing data points of the form $(x, y, z, a)$ where $a$ ranges from 0 to 1 and represents gives the probability density - or "fog" density that should be plottet.

My question is, how to plot this datafile/which ParaView filters to use to create this plot.

• And what is your question? How to do the plot or how to create the input file? – nicoguaro Aug 12 '18 at 14:19
• @nicoguaro I already have the input file, I just can't figure out how to plot it. – HerpDerpington Aug 12 '18 at 14:50
• You need more than just data points to use volume rendering. – nicoguaro Aug 12 '18 at 15:08
• @nicoguaro Could you please elaborate on that? – HerpDerpington Aug 12 '18 at 15:18
• Yes, it is basically the answer of Biswajit Banerjee. You need to have a function define over your domain. For that you need a mesh, a regular mesh is the best option for volume rendering. – nicoguaro Aug 13 '18 at 16:48
