Download the file for your platform. module, Different calling style (returns the new value as opposed to using a double pointer). It does require Cython to install the C code; however, this is available for all supported platforms. Wrappers around the functions are also knows as decorators which are a very powerful and useful tool in Python since it allows programmers to modify the behavior of function or class. The exposed interface supports both asynchronous (e.g., callback) and synchronous (e.g., call and block) functions which is enabled by the C_Sync_Wrapper. This should be a good starting point for writing a Python wrapper for any API out there. Welcome to the PicoSDK for Python. We have been through several iterations of these wrappers in Pure C, Ctypes, and Cython. The majority of the runloop is abstracted so that later upstream modifications will have minimal impact on your code; however, you are free to implement your own runloop and access all available functionality. The wrappers don't work for windows out of the box. Notice: MediaWiki has been updated. brightness_4 Depth and RGB callbacks are given numpy arrays of the returned data. This provides async (e.g., using callbacks) and sync (e.g., simple function calls) interfaces to libfreenect. Since all freenect functions are of the form freenect_blah, we use freenect.blah to refer to them. module-wrapper - module wrapper Python library.
