Thread: [Visualpython-users] Simple question before diving into JPython.

Hello,

Before I dive into JPython, I have a simple question.

I am looking for a tool that can generate a 3D image (and eventually a 3D
animation) from a script.

I know POVRAY, that I've already used. But POVRAY language used to describe
the scene is too limited for what I need to do.

Python, which I already used, would be excellent.

So, can I follow this procedure :

   - I write a Python script that creates one (or several successive)
   scene(s).
   - Then a run Python on the script in order to generate an image (or a
   list of images).

What I mean is : Do I need to run the user interface in order to create an
image (or a list of images) ?

Note : A problem with POVRAY is that we can not call the renderer without
executing the user interface. Well... we can call POVRAY with some command
line arguments. But it is really limited. And the INI file must be assigned
with the user interface...

Best regards,

Denis

In the Contributed section of vpython.org is a module you can import into a
VPython program which generates a file containing POVRAY scene description
language equivalent to the VPython scene. You can then process that file
with POVRAY. Unless you make the VPython scene invisible, the execution of
the VPython program will display the scene, which apparently you don't want
to happen. However, a typical way to use the POVRAY export module in
VPython is to wait for a mouse click before generating the POVRAY file, so
that you can use the mouse to zoom and rotate the scene before generating
the file.

I should have said: You can execute statements to position the camera in a
VPython program and not rely on manual zoom and rotate, if that is
important to you. Also, note that you can write an animation in VPython and
generate a series of POVRAY scene-description files to process.
