Blender to .as3 Exporter for Papervision 3D, Away3D and Sandy3D Updated

If you are exporting from blender to actionscript directly so you can get your models into flash as script you can use the Blender to .as3 exporter which so kindly supports all flash 3d engines currently Away3D, Papervision3D and Sandy3D.  Dennis Ippel made the Blender exporter a while back but the update supports papervision 2.0.

The benefits of COLLADA are nice but there are so many differences that you can run into trouble.  With the exporter it is a direct faces and vector export without all the bloat of DAE/COLLADA xml.  This works if you are only developing for flash and dont’ need to use the models in other platforms/systems/engines that aren’t in flash.

AS3 Papervision 3D Debugging/Stats with PV3DDebug

I have been doing lots of Papervision 3D for a project recently and needed to debug some placement and camera issues.  I did a quick search and found PV3DDebug by Jason Bejot and it worked out great and is a pretty sweet utility I thought I would mention when you need to debug Papervision or even for inclusion as a debug console in all your papervision apps and games. It is a good base for your own consoles or debug panels. It is also a great tool to help out with focus and zoom issues and understanding with camera placement.

The code is really easy to drop in and you can get lots of info on the PV3D scenes and camera manipulation.

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.

Papervision 3D 2.0 Breaking Changes on Object yaw, roll, pitch

UPDATE: See comments and papervision list for revert of this change.  You can now use localRotationX, localrotationY and localRotation Z instead.  yaw(), pitch() and roll() are back by popular demand.

Hi List,

Sorry for this confusion, but we decided to revert back to pitch(
angle ), yaw( angle ) and roll( angle ) methods.

There are three new getter / setters now though:

do3d.localRotationX
do3d.localRotationY
do3d.localRotationZ

So:

pitch( 30 ) would be the same as doing localRotationX = 30;

Note that  localRotationX / Y /Z are rotations relative to the
rotation as set by rotationX / Y / Z.
Also note that after do3d.lookAt() localRotationX/Y/Z will be resetted to 0

ORIGINAL POST:

Papervision 3D 2.0 Alpha has been undergoing lots of changes and one you might want to know about is the object yaw, pitch and roll change.  Thisis changing on how you access them but only slightly.  This is good because you an read and write the values on the object not just set them. Per the papervision list from the man Tim Knip:

On many users request:

DisplayObject3D‘s methods pitch(), yaw() and roll() are now getters / setters.

Usage:

do3d.yaw = degrees;
do3d.pitch = degrees;
do3d.roll = degrees;

var myYaw : Number = do3d.yaw;

This means these values are now ‘absolute’ values instead of previous
‘relative’ values as in deprecated do3d.yaw( 1 );

Let me know any issues (as I’m sure there are…)

Tim

This only affects the latest and greatest revisions of papervision but is definitely a good change.  It is good to make changes that make more sense without worrying about breaking changes.

AS3 Creative Papervision 3D Flash Games

Recently on the papervision lists there have been some really creative uses of pv3d in games. I will highlight two here:

The Bowling Buddies game is made by the very creative Playfish.com company (more on the release at their blog). They have some great facebook/social network games combined with flash. With bowling buddies they created a game similar to Wii bowling (even with customize characters) and the best part is how they have scaled down versions. You can play in 2D, 3D and at different levels of quality to make it accessible to everyone. I think that will probably be needed with 3d flash games (Shockwave Director has LOD (Level of Detail) that helps with scaling down to slower machines but you have to do that yourself with the state of 3d engines in flash so far).

Bowling buddies and most playfish games are Facebook/Social Network based. You might say, why? (especially if you aren’t in the US where facebook is the biggest social network). But even Activision’s CEO calls facebook a threat to online gaming as we know it, this is because of the community aspect and the ability to play with friends and multiplayer games easily. Rather than setting up your own player find mechanism, facebook has it built in and all the viral aspects you need to garner more fans. So those into facebook and gaming are possibly ahead, but also it will be extremely competitive.

Airship is a really creative game that has been impressive to watch grow over the last weeks. It is now textured and performs pretty well. The best part is the Airship model and the fans. Very neat and I hope this one is seen through to a launched game. It is a bit like a RTS/Strategy overhead game that would be very cool to play multiplayer with Red5 server as well (just need the TIME!).

[ try airship demo ]

The best part is you can see after a year+ of release papervision and the other 3d engines are really changing the way gaming is done online. What was once a Java or Shockwave only capability, flash now has with evolving 3d engines, and there are playable fun games to prove it that are commercial ready.

Get your game on!

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.

Overview:

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.

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

Skybox

  • Textures are just jpegs.

Boxes

  • 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

Scene

  • 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 www.custommedia.co.nz up and running and start to post more info then.

Currently implement stuff:
