Poser Python Scripting F.A.Q (Last Updated: 2024 Sep 18 2:50 am)

We now have a ProPack Section in the Poser FreeStuff.
Check out the new Poser Python Wish List thread. If you have an idea for a script, jot it down and maybe someone can write it. If you're looking to write a script, check out this thread for useful suggestions.

Also, check out the official Python site for interpreters, sample code, applications, cool links and debuggers. This is THE central site for Python.

You can now attach text files to your posts to pass around scripts. Just attach the script as a txt file like you would a jpg or gif. Since the forum will use a random name for the file in the link, you should give instructions on what the file name should be and where to install it. Its a good idea to usually put that info right in the script file as well.

If I call a Poser Python script on a model, how could the script look at any one of the mesh vertexes and find (1) that vertex's unposed original coordinates as was in the mesh file, and also (2) where Poser posing has moved that vertex to? I may need both at the same time, for a project that I have in mind.

geometry = poser.Scene().CurrentActor().Geometry()

geometry.Vertex(index) Returns the local space Poser vertex object with the designated index.

geometry.WorldVertex(index) Returns a world space vertex object by specifying its index. If no world space data is available, the function will return None.

Thanks.

If I call geometry.Vertex(i) on point i and it yields (x,y,z), how on my Poser run's stage could the script move that vertex to position (u,v,w) ?

Would thus moving a vertex, automatically also update that vertex's stored geometry.WorldVertex(index) value?

Hello Anthony,

As a basis for writing your script, you can use my script Vertex Viewer Python Script to be found in the free stuff section. The link is: Vertex Viewer script

Once you have defined the vertex you can use its Set method to change its position.

vertex.SetX(value) Sets the X coordinate of the vertex to the value given.

Suggest checking its WorldVertex before and after making a change to see if that updates. I'm pretty sure that it does.
