This so funny. I had not seen this before I uploaded the zips I had to Github. Thank you.

Hello all,

Where can I get "Zsurf4"?

It seems it is not included in Max's mirror.

Edit: is the "Heightmap.v.0.6.2015.08.20.zip " the other name for Zsurf4?

From what little I have read, ZSurf4 is a windows program from circa 2003, well before Max's script. Do the two scripts yield similar results?

It is said: "ZSurf - converts bitmaps to 3D NURBS surfaces"(This may well be False?)

Another link:
https://www.reidb.net/USGS.html
says: "Zsurf4 can be used to convert grayscale height maps to IGES surfaces (.IGS),..."

https://soulysolar.mudventions.com/?p=478
"zSurf4 is a utility that allows you to import a bitmap and export a surface." (IGES)

There is a forum topic on Zsurf4, via a MoI search.

Oh Sorry, I thought Zsurf4 is also written by Max!

Hi Psygorn, yes like Brian writes above ZSurf is its own separate stand alone program which can import a bitmap file and generate an .igs file with a surface in it that can be loaded into MoI.

Some links and previous discussion here:

Max's heightfield script is similar.
