Starting Panda3D

Creating a New Panda3D Application

ShowBase

To start Panda3D, create a text file and save it with the .py extension. PYPE, SPE and IDLE are Python-specific text-editors, but any text editor will work. Enter the following text into your Python file:

from direct.showbase.ShowBase import ShowBase


class MyApp(ShowBase):

    def __init__(self):
        ShowBase.__init__(self)


app = MyApp()
app.run()

Here we made our main class inherit from ShowBase. The ShowBase class loads most of the other Panda3D modules, and causes the 3D window to appear. The run() procedure in ShowBase contains the Panda3D main loop. It renders a frame, handles the background tasks, and then repeats. It does not normally return, so it needs to be called only once and must be the last line in your script. In this particular example, there will be nothing to render, so you should expect a window containing an empty grey area.

Running the Program

On Windows, Python is already included with Panda3D. To run your program, enter the following in a terminal (command prompt):

ppython filename.py

To run it on GNU/Linux or macOS, enter the following in a terminal:

python filename.py

If Panda3D has been installed properly, a grey window titled Panda appears. There is nothing we can do with this window, but that will change shortly.
