Blender to .as3 Exporter for Papervision 3D, Away3D and Sandy3D Updated

If you are exporting from blender to actionscript directly so you can get your models into flash as script you can use the Blender to .as3 exporter which so kindly supports all flash 3d engines currently Away3D, Papervision3D and Sandy3D.  Dennis Ippel made the Blender exporter a while back but the update supports papervision 2.0.

The benefits of COLLADA are nice but there are so many differences that you can run into trouble.  With the exporter it is a direct faces and vector export without all the bloat of DAE/COLLADA xml.  This works if you are only developing for flash and dont’ need to use the models in other platforms/systems/engines that aren’t in flash.

PyAMF 0.3 Released and Sample on Google App Engine

A great Action Message Format (AMF) remoting kit for server side for the pythonistas is pyAMF, they recently released PyAMF 0.3 and have a sample running up on Google App Engine. There is also a tutorial for getting PyAMF running on Google App Engine. Aral Balkan got this running as well.

Features of pyAMF currently:

AS3, Convert Python Code to Flex AS3 with flex-pypy

I have officially been sucked into the Python vortex. I recently have really been digging IronPython, Jython and good old plain Python but have not ventured here yet. Google (They employ Guido), Microsoft (IronPython) and Sun (Jython) are all becoming infected pythonistas as well. But this is just too cool, Python to AS3 code with flex-pypy. This project is very young but could be fun, source at Google Code.

Haxe has a similar premise where it can compile to Flash6-9 versions of actionscript 2-3 which makes for a system with better reach. Python code for this is lots of fun and very flexible. Python is becoming a baseplane language and one great language for transcending platform lock-in.

Check out this snippet pulled from here (click to see sample game)

#/usr/bin/env python

This simple example has very little to do with the pygame
chimp example, except that it will act the same (more or less)
and it uses the same resources, only they got converted to
mp3s, pngs.

Sub Pixel Manipulation with PyGame

Will McGugan posted an article about subpixel manipulation in Python.  This is possible in other technologies like OpenGL and DirectX but Will has implemented it in Python.

Here’s a picture of it in action.  Top row with sub-pixel, bottom row without.
