AS3 Zupko’s Reflections and Shadows with Raycasting in Papervision 3D

The Zupko show continues with reflections in Papervision 3D [demo].

Be sure to check out the shadow demo that this is based on:

After posting my shadow experiment, Patrick Matte posed a question wondering if I would be able to do real-time reflections in a similar manner. The next day I had it done, along with some nice iterations along the way: orthographic and perspective projection (I can release those later if anyone really wants them). I’ve been sitting on it every since and finally decided I would take the time to write a little description into how its done and give the code to those who are interested (and I fixed up some code for backface culling in the reflection this morning).

More Creative Flash AS3 Papervision 3D Games

Here are some really stylish and well done uses of Papervision 3D to make fun games. The people at Bloc recently launched Meta4orce, a unique interactive sci-fi TV show site with some great and numerous uses of papervision 3d.  My favorite is the tron like style and the tower defense game called shock to the system.

AS3 Flash 3D Engine SWFZ Source Code Goes Open Source

Jono is giving SWFZ to science and the open source devices.

The SWFZ engine is one Flash 3D engine that took a different approach. It is a bit early in its technique used but the author at custom:media Jono has decided to float the source code out there in ghost mode (no active development but not dead). It is just ready to branch and others to run with it. He is floating the source but I think in 1-2 years this will be the preferred method if processors and multicore parallel usage is optimized. We shall see.

The implementation method and difference with SWFZ engine in Flash for 3d is that is is a pixel based renderer or scanline. It is based on a really fun game engine called Irrlicht which has been pretty active for the last few years but is a C++ DirectX and OpenGL engine. Since SWFZ has to run in Flash and it is a pixel renderer/scanline it has some limitations currently in Flash. Games and renders have to be fast to pull this off and Flash is limited by the software renderer but as computers get multiple processors and flash player gets better at this then this will be a viable option (it is the same thing that limits Canvas based renderers right now). One main problem with this is you can’t go too full screen the biggest sizes that perform well are smaller windows 320×240 etc. But if the processors can handle it it is actually more efficient when it removes overlap, extra triangle drawing and painters algorithm like problems dont’ pop up (triangle overlap when on same plane). This method draws pixel by pixel but fast enough flash engines like Papervision, Sandy3D and Away3D draw overlaps due to the drawing technique, back to front.

But SWFZ still manages to pull off some amazing feats such as these demos

Quake Demo

Terrain Demo

Yoshis Hip Hop Couzin

Jono has put some great classes into SWFZ engine such as bsp parsers, quake md2 parsers, animated mesh, and lots of great examples in porting C++ Irrlicht to AS3. This was a very early example of how AS3 was fun for programmers to port stuff from C or C++ into Flash. AS3 is just fun. Also be sure to check the site for more samples like an FPS game, some basic ai etc.

Jono has been working on 3d in Flash for a while and actually this message is what shows the difference betweeen this approach and other flash engines the way Papervision, Sandy and Away3D (pv3d derivative) make 3d in flash fast enough (Painter’s Algorithm and drawing skewed movieclips and textures.


More about the Engine Some Notes

The SWFZ engine.


SWFZ engine is the result of four years of me messing with 3D in Flash.

I was a complete newbie to 3D, so a lot of learning has happened to get to here.

If you’re interested in 3D engines check out the resource links at the bottom of the page:

The Demo:


  • .md2 format from ID’s Quake2.
  • Uses frame based animation
  • Textured with jpeg
  • No lighting, No Gouraud Shading, just plain texture


  • Textures are just jpegs.


  • Rendering – Textured Gouraud , Textured Gouraud with Alpha, Textured Gouraud with Quick Alpha, Gouraud Shaded, and the large box is just Textured.
  • Star Texture – Targa (.tga) file format.

AS3 classes

  • 171 classes and interfaces


  • No lighting
  • No collision detection

SWFZ engine technology:

The demo only shows a small part of the capabilities of the engine. In the coming weeks I will get up and running and start to post more info then.

Currently implement stuff:

New file formats supported

  • .tga – Targa Image
  • .bmp – Bitmap Image
  • .3ds – 3D Studio Max
  • .bsp – Quake3 levels
  • .md2 – Quake2 models
  • .obj – Wavefront 3d object (static)
  • .zip – Read from a zip archive (all in Flash, no server side scripts)

3D Rendering

  • mipmaps
  • perspective correct texturing + affine texturing
  • Flat shading
  • Gouraud
  • Textured Gouraud
  • Textured Flat
  • Textured Two Layers
  • Gouraud Alpha
  • Textured Flat Alpha
  • Textured Gouraud Alpha

3D Scene

  • Billboards
  • Parent, Child scene nodes
  • OctTree
  • Skybox
  • Static Meshes
  • Animated Meshes
  • Basic collision detection
  • Scene node animators

If any code is useful to you maybe drop him a donation or what would be nice if this was all setup at google code and used to be integrated into other engines. Irrlicht ports are fun and there is a future in this method when processors catch up I think.

AS3 Nascar Game By mr. doob – AS3 Flash Library Mashup

I have been one upped by mr. doob! I did a little nascar like RC pro am like prototype in march ’07 when the pv3d kit showed up on my screen and I was hooked like most suceptible flashers who have longed for 3d in flash! Only my version is like Nintendo64 and his is like xbox360 with updated effects and physics kits and some doob magic. All these are based off of, of course the original race car driver in Papervision and its creator Carlos Ulloa (Adobe should be paying this man).

To the feature! This is a sweet game by mr. doob, called burn and brag for Nascar.

Now I don’t’ particularly like Nascar all that much but who doesn’t like to peel out to some fiddlin’? I mainly do Nascar stuff because it is highly marketable and like the only answer most ad agencies have for getting the southern us markets it seems, that and c-o-u-n-t-r-y mu-si-c (must be said at a slower rate).

But I digress, this is a perfect mix of advertisment, game play, fun and experience. It is fast, simple, and playable. Exactly the simplicity and smoothness needed of gameplay and playback.  Great ad work but it also gives something fun to do and best of all it is built in AS3 flash with a plethora of libraries from the flash as3 community.

The game platform is emerging fantastically in the AS3 market. mrdoob used these kits to build this:

It would be cool to see a post on how he did the replays with tweener – I imagine just a series of points collected with car state (current position state) and then just play them back with a call back or time delay. You’d have to capture alot for smooth playback without laggy movements.  I am working on multiplayer games with this same issue for a current project.

Game on! The question is when will this be SOTD or SOTM at

AS3 Real-Time Raytracing

Forrest Briggs throwing down with a real-time raytracer in AS3. Also a C++ OpenGL version sample on the page.

Real-time pixel manipulation in flash is getting faster, but is still probably going to have to be faked in AS3, maybe AS4 will provide us per pixel speeds that Andre Michelle has been harping on since flash 8.5. Native operations can be much faster in that area. AIF might look to change some of that but that is Flash 10.

Here is the code for the as3 raytracer. Read more at laserpirate.

AS3 Water Effects in Papervision 3D, Away3D and Sandy3D

I was messing with water effects and Perlin Noise (sandy3d) and some other stuff and collected some water effects and simulations that are fluid like for research, a snapshot of the state of fluid and water effects in 3d in flash.

Ralph Hauwert, of course one of the original pv3d team members, posted some great samples on water effects on 3d objects in Papervision 3D. Of course the papervision list spawned this discussion from another great post on water simulation in papervision and away3d by Exey Panteleev .

Also, some other water like effects from Fabrice Closier and the notorious mrdoob.

Ralph’s Water Effect Demos:

Hey look, the water ball is smiling at you.

Exey Panteleev’s Water Simulation:

Some other Water Like Fluid Effects:

Water is hard in flash. Fluid dynamics will probably have to be cheated but it is still looking pretty good. The amount of processor usage depends on how real you want it to look.

If you are looking to make some agua, with x, the y AND the z in Flash or Flex, these are a good place to start.

AS3 2D Physics Engine Motor Physics Released (Motor2)

Great news! Polygonal Labs has released the long awaited Motor Physics engine. It is now called Motor2.

UPDATE: Now hosted at Google code

Project hosted at
License: New BSD License

After the port of Box2DFlashAS3 appeared the fate of Motor Physics engine was unknown. But with time and just before the stroke of midnight on the final hour of 2007 Michael Baczynski released Motor2 2D physics engine on the world.

This now gives us, count them, FOUR AS3 Physics engines that were released in 2007 in order of release.

Be sure to check the demos of Motor Physics:

To get the source head on over to the blog and in the post it is in the first para.

Currently you can get the source for the preview here.

Polygonal always has such great information and demo write ups the source link gets lost in there. Hopefully this will be at Google code soon or a public SVN. The code looks great and there are optimizations in there but even those are elegant.

With 3 excellent flash as3 3d engines (papervision3d, away3d, sandy), 4 physics engines, lots of great utilities like FZip or ASZip, AlivePDF, Red5, haXe etc etc. 2008 is looking like it will be a great year for performance, optimization and gaming/app platforms on the web like never before seen. I am most looking forward to the coming gaming market for flash, lots of possibilities. With the added competition from Silverlight, much innovation will happen here.

It is great that Motor2, which has a great author and dedicated to performance has joined the physics engine scene, not only that posting on new years eve. Thanks to all that make the flash platform possible of creating excellent new fun and useful tools.

AS3 Papervision 2.0 Alpha (GreatWhite)

Only a year after release Papervision is getting a major update to 2.0.

Get it while it is hot from the SVN server on google code:

Papervision3D, launched a year ago, really sparked the AS3 and flash/flex world and inspired every flash guru I know into working on this code. There have been some great tools made and some fwa’s won but it is only the beginning.

I am mostly looking forward to performance enhancements, ascollada integration, culling and Andy Zupko’s 2d bitmap effects on 3d.

New features:

  • Faster!
  • ShadeMaterials
  • Shaders
  • ASCollada (animation support)
  • Frustrum Culling
  • Multiple Viewports (3d editor anyone?)
  • Render to Scene
  • and more!

SVN server and branch:

We do indeed like to ride the racecars!

AS3 Papervision3D 2.0 and 2D BitmapData Effects are Evolving

Andy Zupko is probably doing some of the coolest / useful work in performance and possible effects combining 2D and 3D. Using 2D BitmapData and papervision 3D it turns out you can create a parallel dimension of coolness that cannot fully exist by themselves.

Papervision 2.0 with these effects and if it is as pluggable as it seems is very good for games that lighting is a key component or effects. Imagine a game that can customize weapons with 2d effects in 3d, or rocket boosters, or fireworks or all kinds of inspiring things like changing the mood or environment such as fog, lighting etc… If you start taling about adding physics to all this it just gets too fun. Effects have always been there and around, but making this possible to have a semi-standard way to do this and if it is pluggable, this can lead to many engine advancements.

I think the PV3d team additions of Tim Knip and Andy Zupko have been very good and zupko era in PV3d has begun. Tim Knip is also very active and helping to really organize the ascollada formats and performance stuff like only drawing what is on screen.

Who needs Hydra now? j/k although having this now in papervision leads me to see a very fun 2008 ahead for Flash, it is also, if as pluggable as it seems, a bit like a shaders kit.

All those older great 2d effects merging into 3d from the good old days (some still going very strong) of praystation, yugop, levitated, neave (great 2d tv effects in , flight404 (moved to processing) and many others. And a new era of zupko [pv3d], mr. doob, unitzeroone [pv3d], fabrice [away3d] and many more a new 2d effects in 3d platform is emerging. This kit for papervision3d by zupko and Hydra is making the future glowing full of bright points, and lots of effect explosions.

Let’s hope papervision3d 2.0 it is released soon and it has zupko’s effects code in there.
