Came up with this which is fun to play with.

Interested to see this appear yesterday at everydayflash.com and made a quick start on a sandbox for it to get ideas on how to use it with Papervision.

A first example of AS3DMod which is a sandbox to experiment with can be found here.

Updates: Some usage tips noted for the initial version of the library using pv3d

* Seems to work fine with current SVN build of PV3D

* in com.as3dmod.modifiers.Noise.as comment out line 9:
import alternativa.types.Matrix3D; (the import is not used but will error if you only have pv3d library)

* Grab com.carlcalderon.arthropod.Debug.as from here and put it in your path as it is used in several of the files.

* Added simplfied usage code to the example here

* Added examples below using svn build.

Noise – sandpaper to mountain range: AS3DModNoise.as

Taper- rip and shrink: AS3DModTaper.as

An idea for a Fish

Added some more Papervision 3D examples with source code.
All examples use current Papervision3D GreatWhite from SVN and so far all use BasicView also. **Update:** added four more examples to the top of the list to make 18 in total:

• InteractiveScene3DEvent example

A clickable Plane with a swapped material that rotates using Tweener

• Layers Demo

Setting the layer order of objects to try to control which is on top

• Simple Wow Engine Demo

Spheres contained in a Cube

• Rotation Demo

Shows three rotation axes

• BitmapFileMaterial example
  

Using BitmapFileMaterial to load a jpg and provide texture for a Plane

• Two Sided Plane

Extended DisplayObject3D to create a Plane with Wireframe one side and MovieMaterial on the other

• Video Cube Demo

Displaying a flv on the inside walls of a Cube

• VideoStreamMaterial demo

Using VideoStreamMaterial to provide a texture for a Plane

• Sphere BitmapMaterial

Using BitmapMaterial to display a jpg on a Sphere

• Blender Collada DAE

Loading a Collada DAE file exported from Blender

• Blur effect

Simple example using the newly integrated Effects branch

• Curved lines

Using an external class to create curved lines

• Lines3D

Using the built in Line3D class to create straight lines

• Particle field demo

Simple ParticleField example

• Bitmap material demo

Basic BitmapMaterial example using an embedded jpg


• Rotating cylinder

Cylinder with FlatShadeMaterial

• Shaded cube

Cube with FlatShadeMaterial

• Plane wireframe

Simplest Wireframe Plane

Added a Comments viewer, and a related movies tab using the as3-youtube-data-api

View the flex swf here

Loading the comments is almost identical to loading the feeds – just use these classes :
import ca.newcommerce.youtube.data.CommentData;
import ca.newcommerce.youtube.feeds.CommentFeed;
import ca.newcommerce.youtube.events.CommentFeedEvent;

The rest is the same.

Previous version with source code here

Flex YouTube API feed + search display. download source code here

Uses library @ as3-youtube-data-api

Nice player example @ on_the_other_hand

author of as3-youtube-data-api has a blog @ blog.martinlegris.com

update: added in a simple player to view the movies.

.
Update 2: Added source code download for the feed display
We are making a Cairngorm version of this but here is a simple component version to test.
The source code for the feed display component (not the player) is here
It is a FlashDevelop3 Beta7 project file and uses the Flex3 SDK to compile. To build the project requires the as3-youtube-data-api library Just download youtube-google-0.95.zip and add it to the project path and compile, that is it.

All of the hard work is done by SimpleFeedGrabberExample.as which uses the excellent as3-youtube-data-api library to load feeds from YouTube and parses them into an ArrayCollection which is the Bindable datasource for the display. This is a simple version that will likely change a lot when it is in our Cairngorm project but works fine for now.
as3-youtube-data-api notes: in strict mode you get a few warnings of variables declared without datatypes in the as3-youtube-data-api library but these are easy to fix. Also YouTubeClient has been removed in the library version released yesterday but we substituted YouTubeFeedClient in its place and that seems to work ok.

—
Once the above is complete to integrate with into the otoh player grab the source code from here:
* copy the src directory into this project src folder
* make YouTubeTest.mxml the target file + make 3 edits to it:
* put xmlns:ytfeeds=”ytfeeds.*” in the Application tag at the top
* put <ytfeeds:YTFeedComponent top=”325″ /> just before </mx:Application>
* insert your YouTube Developer key into YouTubeTest.mxml and compile.

Now when you click on a movie in the display it can be played in the otoh player because video.text is set to the selected movie ID.

Update:
Added a Comments viewer, and a related movies tab using the as3-youtube-data-api

View the updated flex youtube movie here

An alternative to excessive typing or copy + paste that is worth consideration is a Cairngorm code generator like The Cairngen Project

Project now moved to GoogleCode

I got some useful feedback at Flashcoders about my SVG post below. So far from what I found there is no golden rule for predicting filesize when embedding svgs except that usually the swf will be smaller.

I tried some of the suggested Inkscape optimising tips (ungroup,convert to paths, removing metadata/gradient definitions) and others (Vacuum Defs, Paths simplify) but none had a notable filesize impact once that particular svg was embedded in Flash (although they do benefit other svgs).

The main culprit seems to be the three shadows below the base and one once they were removed from the svg took the resulting swf from 63k down to 30k which is roughly the svg/swf ratio I would expect.

Below left is the original monitor and the edited one one on the right, those shadows below the base add 33k (over half of the total).

One related thing I found is :

Original monitor svg = 64k adds 63k to the swf when embedded alone
Edited monitor svg = 69k adds 30k to the swf when embedded alone
Embedding BOTH svg files in the SAME swf adds only 63k to the swf

I am guessing that the reason why is that when converting embedded svgs to swf the Flex2 SDK caches paths and gradients converts them to symbols in the library so that if it finds the same definition in another embedded svg it pulls it out of the library instead of recreating it. But I would need to test it some more to be sure. Cool if it is though.

Adobe have released the Linux Flash 9 beta player. Available for download from here http://labs.adobe.com/downloads/flashplayer9.html
Hope it works out of the box on my Ubuntu.
The little discussion here says it should work fine :)

Update:
Actually it was simple to install
standalone: just su to root and unzip FP9_standalone_beta_101806.tar.gz and extract gflashplayer to your /bin directory
Firefox: just su to root and unzip FP9_plugin_beta_101806.tar.gz and extract libflashplayer.so to your /usr/lib/firefox/plugins directory

and so far it works just right too :)

Some discussion of the plugin at Ubuntu Forums and at linux questions and a positive review here
