Loading a File
This topic explains how you can load a file from the disk and buffer memory.
Loading from the Disk
The following code sample shows how to load a file from the disk using the FBApplication.FileOpen() function.
from pyfbsdk import *
app = FBApplication()
filename = r"C:\Program Files\Autodesk\MotionBuilder <year>\OpenRealitySDK\scenes\PlasticMan.fbx"
# Open the sample file "PlasticMan.fbx", and prompt with a
# UI dialog as indicated by the second True argument.
app.FileOpen(filename, True)Note: It is a best practice to specify an absolute path as an argument to
FBApplication.FileOpen(). If you specify a relative path, it corresponds to the current working directory of MotionBuilder. You can change the current working directory in various ways. For example, by manually opening a file or invoking FBPopup.Execute() to specify a location for saving or loading a file.Loading from the Buffer Memory
To load data from the buffer memory, you must pass the raw address of the buffer memory to FBApplication.FileOpen() instead of a file name. The following code shows how to load data from the buffer memory using FBApplication.FileOpen().
from ctypes import *
fbxfile = r"C:\Program Files\Autodesk\MotionBuilder <year>\OpenRealitySDK\scenes\PlasticMan.fbx"
f = open(fbxfile, 'rb')
buff = create_string_buffer(f.read())
f.close()
FBApplication().FileOpen(addressof(buff), sizeof(buff)) # You can open this file from the memory as many times as you want.Replacing, Merging, Appending, and Importing
You can use functions in the FBApplication class to control the data loaded from a file. The following table describes these functions.
