Program for plotting points in 3d

[Armus]

Can you guys recommend a simple program (preferebly freeware) that can plot points in 3d space?

It would be nice if it could read in a simple format (like a text-format where each line contains a vertex (x,y,z)) and plot them in 3d space.

Metasequoia. It's free, and it's a text format. And it comes with a fully functional 3D editor.

Object "hand" {

Seconded - Metasequoia
Here's my loong .fak vertex plotter :- http://uppit.com/f3hyb9a9fqq0/Fakverts.zip
The bit to just plot vertices is real simple, you make 2 point polys.

Code: Select all

        for i in range(0, numvert):
            of.write("2 V("+str(i)+" "+str(i)+")\n")

example for a cube

Code: Select all

I used mqo as my main exporter awhile back. It was a multi-format 3D converter I had planned to add to blender as well (kind of like the fatImporter for 3d max), with a single interface required for all plugins.

Too bad it doesn't support normals.

It would be nice if it could read in a simple format (like a text-format where each line contains a vertex (x,y,z)) and plot them in 3d space.

Just use the 3D Object Converter's 3D Points .txt load module.

See the attachment and in my program turn on the Vertexes using the CTRL+V hotkey !
