Tatlin is a Gcode and STL viewer heavily inspired by Mac-only software Pleasant3D. Besides viewing, it also supports rotating and scaling of STL files. It is currently in early stages of development, but should already be quite usable.
Tatlin requires the following packages:
-
Python 2.6+
-
PyGTK 2.24
-
PyOpenGL
-
Python bindings for GtkGLExt
-
NumPy
To launch Tatlin from the command line:
$ python tatlin.py
You can also provide a filename to load:
$ python tatlin.py foobar.stl
Mouse navigation
-
Left mouse button to rotate
-
Mouse wheel to zoom
-
Middle mouse button to offset the platform
-
Right mouse button to pan
Build platform size can be customized by creating a file called .tatlin in
your home directory with the following contents:
[machine] platform_w = 300 platform_d = 300
