Seraf, True to the word WOWEngine was released today. It is still a work in progress but it is the first 3d physics engine out of the gate. It is built with many open source kits that are emerging. It can use any of the 3 major flash 3d engines (pv3d, sandy, away3d) and it is built on APE AS3 2d physics engine.

WOW-Engine use Sandy library for all the 3D mathematical computations (matrix, 3D vector, plane). The inner architecture of the engine is also inspired by Sandy’s one.

Collisions and physical reactions are possible thanks to the AS3 physic engine made by Alec Cove, named APE(version 0.2.).. Even if APE is a 2D physic engine, it is possible to extend the contraints on volumes, and that’s the purpose of WOW-engine. WOW-engine extends APE, and allows to simulate physics on 3D volumes.

WOW-Engine is capable to handle positions and rotations of abstract objects, which need to be linked to some visual objects (2D or 3D). The visual objects can be drawn thanks to another library (Sandy3D , Papervision3D, Away3D for 3D).

WOW-Engine use and depend of the Data Structures classes written by polygonal labs.

Who’s up for some flash 3d gauntlet? Away3d and Fabrice have posted a pretty sweet demo that samples a 3d level with a little 3d avatar running around (animated).

Fabrice has some other good notes on keeping assets in flash low poly and not relying on full 3d or shrinking that down where possible. For instance in making the walls they are more dynamic and just extrudes not really 3d point collections.
Most 3d usages (even outside flash) resort to this to make sure the featured 3d models get all the processing power and polys needed to look good but still be optimized for flash 3d (fake software rendered 3d — slower). I agree and also am interested in loading 3d flash assets as compiled SWFs, but that has it’s own set of duplication whoas. It has to be designed/planned very smart to pull off a game that can perform well.

The stuff for generating 3d worlds in flash from the FPS demo from Animas (Paul Spitzer), the intense work going on at Alternativa Game, toolkits like AS3 Geometry Exporter for 3dsmax (to away, sandy or papervision 3d format/types). And of course all the great 3d engines, physics engines and animation kits that have helped make the 3d flash pipeline for actionscript 3 (as3) a little more optimized and quite fun.

shirotokoro has created something interesting in the view of a pipeline for getting assets from 3d into the new Flash 3D engines with a Geom Class Exporter for 3ds max for PV3D, Sandy and Away3D.

One of the difficulties is the DAE/COLLADA and ASE imports dynamically at runtime in Flash 3d Engines sometimes takes some work to clean up the 3d objects in COLLADA xml or the ASE or 3ds if you are Sandy. But this takes that step out of the process and exports 3d models straight to flash 3d engine object scenes.

This is great for models that don’t’ need to be dynamically imported/parsed (which takes lots of time usually to parse the DAE in flash). I am not sure how detailed or elaborate the models can get as I haven’t had a chance to play with it yet but it is an interesting idea and development but the cat samples he has are fairly complex for a flash 3d engine and they look great. I think this can be used elsewhere preparing objects for 3d in flash as precompiled movieclips already. Maybe even a turbosquid like market for flash 3d. This could be fun.

from shirotokoro via pv3d list:

AS3 Geom Class Exporter is a 3DS Max designed script that allows you to directly export 3D models to AS3 classes.

he benefit is that you don’t need anymore to load and parse a texte file (ase, obj, 3ds).
You just have to import the class and to create an instance, like you do with usual objects like plan, sphere and box classes.

This script is compatible with the following AS3-3D engines :

Away3d
Sandy 3.0
Papervision 1.5

Installation :

Download zip file and unzip in any folder.
In 3DS Max, tools tab, open the maxscript panel and click the “execute script” button.
Select the script. It is now displayed in the available scripts list.
Select it, a new AS3 panel “AS3 geom Exporter” appears.

Options :

- Package : the exported class package
- ClassName : the class name
- Engine : the 3D engine you want to use
- Scale : scale the 3D object
- Swap face normal : with some 3D models, the faces export is swapped, you can fix this by selecting this box.

Here are rendering examples of an object in the following 3D engines :

Away3d
Sandy
Papervision

Thanks shirotokoro !

mr doob has posted a first away3d verses papervision3D test for the same model and found pv3d to be faster than away3D. Who wants to take the source and test it on Sandy?

Disclaimer: Test can vary on types of content and different systems or browsers to it is not a definitive test just one test, more will be coming and the faster it makes engines the better for adding more content to each project.

Papervision3D (src): 14FPS, Memory: ~8,5Mbytes
Away3D (src): 10FPS, Memory: OPS!
Away3D (CORRECT_Z_ORDER) (src): 5FPS, Memory: OPS!

So far there are a few good flash 3d engines But it will all come down to performance for the best.

The top three are the only ones viable for full screen and projects that can cross into the commercial realm, other pixel level systems like scanline z-buffers in flash are really just tech showcases right now.  The fast and dirty Painter’s Algorithm of Papervision and drawing things the fastest wins out when dealing with software rendering and processor based graphics.  When and if 3d acceleration is added, that will change the game immensly.

Who’s got the textures and cool chrome shiny 3d objects in Flash? There have been lots of materials work recently from papervision list developers and away3d developers (away3d is a branch of Papervision3D) and recently it is heating up a bit.

Early on on the papervision3D excitement, flash possibilities in 3d with AS3 specifically, much of that was due to 3d in flash but also the ability to texture and have bump mapping, toon rendering/cell shading and other neat effects like baked lighting, faked real-time lighting, video and movieclips on flash 3d objects and animated textures.

But when it comes to environmental mapping and true 3d reflection that might be simply stretching Flash to a limit that might require hardware acceleration but that isn’t stopping some.

I am not sure if environmental mapping will every be possible on a large scale without hardware acceleration. Pushing the limits could help influence Adobe to the market direction. But then again I never thought I would see the level of 3d in flash that we have and maybe in 2-3 years with multi-core processors it will be possible.

Here’s a snapshot of the current materials and environmental mapping (fake and real attempts).

UnitZeroOne first environment mapping /bump mapping:

Weird 2

Recent work by actionscript architect

Perlin noise algorithm to animate texture real-time into water effect

More environmental mapping effects by the away3d materials developer Fabrice. Fabrice and the away3d developers are really taking off with the papervision3d core. I am seeing lots of engine limits tested and some great work at away3d.

Bumpy Meteor

Flat Lighting on bitmapMaterial

Chrome Ball (dont’ zoom in too far :) )

Did your processor melt yet?

I think that for games and flash effects faking it or real environmental mapping will have to be judged by what is needed for your purpose. I think that Flash player on software rendering can only go so far. So if you have real-time environmental reflections and surroundings it doesn’t always make your gameplay better and it won’t make your demo better if it means removing assets in other areas to make up for the performance drain of software rendering and the pressures it puts on the processor or browser plug-in.

You can still make really killer effects with baked animations, fake environmental mapping, faked dynamic real-time lighting and other effects. Flash, nor silverlight, will not be able to match hardware rendered shaders, per pixel lighting and physics anytime soon. But people are making good progress on this. I think it would be great if hardware acceleration were added to both Silverlight and Flash, with that, a brand new massive game market online, and it will be game on!

The actionscript architect Paul Spitzer has posted two killer demos of pathfinding using A* in AS3/Flash 9 using the Away3D engine (derivative of Papervision3D that is taking off) and you can download the source for both. These demos not only highlight the pathfinding but also provide editing of the graph to be traversed which could easily be made into a game world editor.

Paul adds to some path finding work with the likes of Zeh using Tweener (the best animation kit for AS3 yet) with the bezier papervision pathfinding and the good work going on at polygonal labs in data structures for games and their usage in pathfinding for gaming in flash.

At the actionscript architect’s blog check out the true 3d path finding in all three dimensions, and a 2d based pathfind using A* algorithm in 3d.

Here’s the 3d pathfinding with true 3d (x,y,z) points used in the path.

Here’s the 2d pathfinding with 3d interface.

Paul has been doing very cool vector work from video on 3d in flash using papervision3D, to being one of the first people making demos for WPF and Silverlight such as the Northface Demo.

If you are working on path finding or gaming in AS3 be sure to check out Paul’s work, Zeh’s bezier pathing in papervision and polygonal labs often.
