analogd’s workshop at the Flash Summer Camp Berlin 2009

Few weeks ago I gave a workshop about Real Time 3d in Flash in Berlin during the Flash Summer Camp Berlin. To start with, I would like to thank the organisers, Bettina and Mathias you did a great job the venue was amazing and the organisation worked like a Swiss watch icon wink Flash Summer Camp Berlin   Think In 3D Workshop    Follow up image
I would like to thank also everybody who attended this workshop, especially because it was on Sunday.
Thank you for your positive feedback, I really enjoyed talking with you about Flash 3D. It was also nice to see that they were experimented 3D people in the audience. The audience was varied which brought me to build a workshop not focused very much on code but more on concepts. I know that could have been frustrating for some people and I will try to address this by posts targeted on code in upcoming weeks.

Workshop Think in 3D: follow-up

To start with I would like to tell people, because somebody asked, .ch is for Switzerland (Confoederatio Helvetica), I think I should switch for a .com now icon wink Flash Summer Camp Berlin   Think In 3D Workshop    Follow up image Happy to see that Duanne Nickull knews about it icon wink Flash Summer Camp Berlin   Think In 3D Workshop    Follow up image Cheers from Switzerland.

You will find below the first part of the workshop’s follow-up, it gives you further insight by theme about subjects discussed during my Workshop at the Flash Summer Camp Berlin, checkout also the pdf of the full workshop below, it includes plenty of links which were not presented in Berlin.

Good to know

They are often situations where you need to match 3D to 2D and the reverse, especially if you use 3d as a transition effect or as Wow effect within a 2D interactive design. Please find below a helpful link to achieve this:
Pixel Precision in 3D match 2D and 3D.

During the workshop I told you about using Unwrap and baked textures, here is for reference a simple explanation of it. UVW Unwrap allows you to unfold a 3D object on a flat plane. This technic is often used to add “baked textures” to your 3d objects. Baked textures are textures with lightening and shadows prerendered, leveraging your scene from the computer intensive real time lightening. This technic has been used a lot within the gaming industry and fits perfectly the context of Flash Real Time 3D. For example take a cube, unwrap it. Now you have a flat representation of each face of your cube, then you can export it as an image file and edit it in Photoshop. Once done with your modifications (adding for example shadows and lightening or swapping Flat texture with more realistic ones), you apply your modified image in your 3D software, and now you have your model with prerendered lightening and shadows ready to be exported to Collada and to be used within Papervision3D or Away3d or Alternativa3D or …
The previous example was
only given for the sake of explanation about UVW Unwrap. Most of the time 3D software allow you to directly bake the lightening and shadows as you set it up in your 3D environment to your texture (look at: Render to texture).
Checkout this tutorial by Blitz Lab about Unwrap, Baking a texture and Collada exports.
Checkout Texture Baking is your friend.
Checkout this tutorial about AS3exporter and Unwrap.


As mentioned during the workshop you should use the class instead of the class (Collada can be used for quick tests). The former is more advanced, loading is well managed and plenty of features are supported.
Regarding Collada you should look also at loading zipped Collada models using fzip or using the new Papervision3D KMZ Parser. KMZ files are Google Sketchup files, a zip file including an XML Collada and its related textures. Both technics can reveal handy if you have plenty of models to load. Check this blog post about loading zipped collada models within Papervision3D.
I was asked about how to deform a Collada model, here is links to resources: Using Collada Bend Modifier which uses as3dmod (see below for further explanations).


There is a great Getting Started video tutorial serie about steps to create ID Software MD2 models for Flash Real Time APIS, check this out if you are interested in MD2 animated models: Step by Step Tutorial creating MD2 Models by Michael Lively

An Away3D feature allows you to make smooth transition between MD2 keyed transitions. It is extremely useful to people working on 3d games: smooth transition of MD2 Keyed animation.

3D API tools

AS3geom exporter: a 3ds Maxscript which allows you to export your 3ds Max models as .as class files (for Paperversion3D, Away3D and Sandy3D). Can be useful if you need to embed a model, but should be used with care if you need to embed a lot of various 3D models. Loading of external Collada files should be preferred, (or you could export multiple models then embed them within a swf or numerous swfs and then load it using modules)

Flash 3D Modifier API: Any regular 3D Software has its own Modifiers Library. To be short, it provides you a way to modify various aspects of your 3d object or/and add further edit options. It is usually based on the Decorator Design pattern, hence it is non-destructive. Now Flash 3D APIS has its own: as3dmod.

Spring Camera: a camera with natural movement useful, for example, for FPS or games: Spring Camera by Agit8

Jiglib 3D Real Time Physics Engine ported from c++, is an engine which adds physic qualities to your scene, the same as Havok works for 3ds Max.
There is also WOW Physic engine based on APE, but recently Jiglibs brought a lot of excitement within the Flash 3D community. The question is: has Flash Player power enough to manage Real Time 3D rendering AND Real Time Physic simulation?
Here is a game demo using this engine: 3D Ball Adventure.

If you are interested doing Augmented Reality within Flash checkout the following: FLAR Toolkit and Lee brimelow Getting Started tutorial. I have started a blog post serie about Augmented Reality following a conference I did some time ago, check it out if you are interested in this.

Flash 3D API Editors

There is currently a “trend” starting for Flash 3D APIS to propose users “live editors/builders” to allows them quickly setup their 3d scene. This is a good opportunity also for non 3d people to getting started.

This is a promising initiative by Juxt Interactive to be used with Papervision3D: VizualPV3D by Gary Stasiuk, the task is huge and a 3D software is something very hard to build especially regarding user interface, I wish Gary a lot of success in his work!

John Grden is also working on a PV3D CS4 integration which is not available yet.

Alternativa3D Team is currently working on this kind of tool for their registered clients.

End of part 0

This is it, for the first part of this follow-up to my Flash Summer Camp Berlin workshop. I would like to thank Carlos Ulloa (Papervision3D), Rob Bateman (Away3d) and Alex Karpovich (Alternativa3D) for having so kindly answered to my short “Interview” which was amazingly helpful to build this workshop and tell people about the latest news within Flash Real Time 3D APIs.

The 21th April 2009 in Geneva, I made a presentation focused on Augmented Reality (AR). You will find at the bottom its teaser. As promised to people who attended this presentation, I will publish it as a serie of blog posts including a fair amount of video links and references and several enhancements and details.

What is augmented reality?

“An AR system supplements the real world with virtual (computer-generated) objects that appear to coexist in the same space as the real world” Recent Advances in Augmented Reality, 2001, Azuma, Baillot, Behringer, Feiner, Julier, MacIntyre

“Augmented reality (AR) is a field of computer research which deals with the combination of real-world and computer-generated data (virtual reality), where computer graphics objects are blended into real footage in real time.”


I am not a specialist of AR and what I present is from a personal exploration standpoint, if you are a professional of AR or have extensive experience in it or have a business build around it please feel free to comment on this serie or provide extra links to papers.

Objectives and future

The objective behind this presentation was to show that there is much more behind AR than just “buzz effect” and they are already viable commercial products based on AR concepts.
Personally speaking I feel it is the next upcoming media revolution. I am convinced that AR devices will be everywhere as it happened with mobile phone (or is it mobile phone used as AR devices which will prevent true AR devices to be success full?), even if people might be socially more reluctant to accept it. Of course this is linked to two crucial points: how efficient would devices be to perform live tracking and how affordable would they be.

As far as I can see the upcoming device by Vuzix might help having more people buy AR based devices. Sony has also one in preparation even if Tom Hanks is not that much keen on it: here. I am looking forward to seeing appear an hybrid device allowing full non transparent video display and semi transparent display for AR.

I feel that the video games industry might help also spreading AR concepts. I will not be surprised that the next generation of portable system by Nintendo would use AR (or maybe is it too early?).
(Nintendo GAR, Game bAR or GAR Boy or AR WII icon wink AR you there? Serie on Augmented Reality, Part 0 Introduction image or WII AR (the champion)
Maybe it is the revenge of Gunpei Yokoi after the mistake of the Virtual Boy …)

All in all AR opens a complete new field to explore and to start new concepts and products. It is an exciting time because true commercial solution starts to emerge, time to be creative with these wonderful new worlds opening ….

Presentation’s Teaser

“The 21th April 2009 in Geneva, I am giving a presentation focused on Augmented Reality. It has been a long time that scientists make experiments on this matter, but it is recent that big brands use it to create new ways to communicate about their brand or new products. AR in some of its current use is sometimes just seen as a new way to create buzz and waouw effect for a given brand, but they are much more behind Augmented Reality. AR opens a wide new area to explore new ways of communication, new services and new products. Today it is much easier to build projects based on Augmented Reality and the recent Flash platform port of the AR toolkit will certainly play an important role in increasing the amount of AR products and allow projects based on AR to reach a wider audience. This presentation will include an introduction on Augmented Reality, present a wide range of existing examples and propose hands on Flash Augmented Reality demos.
So be there to meet AR.”
