papervision3D - face level interaction

the new pv3d 2.0 release features an entirely new way of dispatching and handling events. earlier versions of the engine utilized two different flavors of materials, regular and interactive. with this new release, you just have materials with a boolean interactive property.

with this simple demo, im trying to learn more about the new interactive scene events. first, you create a 3D scene, and set it's interactive flag to true:

view = new Viewport3D(width, height, scaleToStage, interactive);

then create a material and set it's interactive property to true:

flex forms as 3D textures

code :: use the bitmapData of any flex component

3D flex components

i guess this is more of a test then a real demo. in flex its extremely simple to access the bitmap data from any component on the screen as it is styled at that time. this includes things like text with in a text box.
in this example, create a flex panel

<mx:Panel id="myPanel" /> 

then create a bitmapdata object

var formTexture = new BitmapData; 

then draw the panel right into it

formTexture.draw(myPanel);

then I use that texture on a 3D plane with the help of papervsion3D. and a little glow filter just because...

papervision3D 2.0 - dynamic lighting demo

lab :: let there be dynamic shaders!

working with the new pv3d 2.0 release, there are a lot of new features to learn. one of the most powerful being the new pointlight3D class. using this will allow you to create all kinds of cool shading effects. at first i was having some trouble deciding where the light is positioned by default. i tried setting the light’s visibility flag to true, but it still wasn’t rendering. after a bit of digging i discovered that the position of the light by default it set to (x:0, y:0, z:-1000), no wonder it wasn’t rendering, it was in the same position as the camera! 

so i decided to make a little flex demo for the new pointlight3D class. the flex form allows you to use sliders to move the x, y, and z position of the light, as well a an orbit function.

as3 geometry class exporter

code :: export 3D models to flash

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)

select model

actionscript 3 runtime variables

code :: setting them with php

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.

3D sound visualizer

code :: papervision3D spikey ball

papervision3D sound visualizer

a fellow papervision3D enthusiast zeh (creator of the popular mctween) has created a new way of animating full 3D objects in the flash/flex environment with 100% code! introducing the caurina tweener, which is now hosted on googlecode. tweener is still in development, but is completely stable and functional.

check out the sound visualization demo i created using pv3d and tweener
