a new component for 3D studio max has arrived that allows you to export the geometry of you model directly into a format that actionscript 3 can understand. the plugin has options for exporting to papervision3D, away3D, and sandy3D. it was developed by seraf and can be downloaded here. and exporting a model couldnt be easier. 

step 1. create you model, and select it 
(you can tell its selected because of the white bounding box)

the key to creating dynamic systems on the web is the ability to send and receive data from one component to the next. flash and flex are no different. there are a lot of cases where you need to send these variables while the application is running, but there are an equal amount of times where the application needs data at run time. passing variables to flash historically has been rather easy, you just query-string data right into the src tag of your flash movie:

src="test.swf?passed=hello"

by doing this flash would create a new variable (in this case named passed) when the flash movie is loaded. but with the advent of OOP coding in AS3, this technique has become depreciated. 

in actionscript 3 you need to use the flashvars parameter to send data to your flash movie. the technique is the same for both flash and flex, but once the variable is passed flash and flex has a different syntax to access these vars.

here is my asp.net randomizer class based on the c R250/512 shift-register sequence random number generator, by kirkpatrick and stoll and published (j. computational physics, vol 40, pp. 517-526) with an added a pseudo-random class redefinition and buffer overflow protection.

example usage:

randomizer x = new randomizer();
int num = x.random();
