Dear GMT users,

I want to plot 3d model like in the example figure. I have got separate columns for longitude-latitude-value-depth

What is the proper approach and which gmt commands should i use in order to get this model ?

Thanks in advance

I’m afraid this is not doable in GMT.

@Luojiahong

It looks beautiful. After almost four years I wasn’t expecting an answer. Thank you so much : )
