Let me know how it runs on your machines

Stay tuned

here’s the link http://www.flashfuck.it/test/pv3d_isometry_01/

this is just the beginning…it has to be tuned and refined but, yes, it can be done

PS: I stolen the model somewhere on the web…please if it is yours don’t offend yourself, i stole it because it’s good (anyway let me know so i can put your name somewhere )

A new contest has been lauched by pv3d guys. Just make an opensource “something” using Papervision3D framework and submit!

Deadline is 15th August…then a new PaperKing will sit on his 3D Throne

Get here for more information

stay tuned

I’m trying to get a usual “virtual world” scene (such as second life’s) using (possibly free and open) as3 3D frameworks, so my first choice has been papervision3D.

Unfortunately I’m not a 3D modeler so I had to get models from the web, anyway google sketchup warehouse is a very good resource to collect DAEs (but remember they may be not parsable by ascollada).
For the human model I’ve just “stolen” a walking girl from 3Dflasho.
…and here‘s what I got combining the 2 models: a girl walking in a stadium. (girl is automatically walking forward, just use left and right arrows to make her turn)

(note: textures are about 7 mb and the whole swf is very cpu intensive) 

Take a look to the profiler, you can notice that framerate is very low even on a very good machine (i had a value range from 12 to 18 with everything loaded and 26\28 for the girl only on a macbookpro 2.4ghz and flash player 9.0.124 debug).

Next steps for me are:

1) try the same models on Away3D and maybe on Alternativa

2) search for better models (expecially for the stadium which generates too many culling issues on the ground)

3) have a mana potion

I hope to get good news from papervision and away3d mailing lists about flash 10 implementations, expecially about both engines’ drawing speed..in the while I’m going on with my tests

I highly suggest to take a look to those interviews, just to be aware of what’s going on

here’s the links:

• http://dailypv3d.wordpress.com/2008/05/22/interview-with-ralph-hauwert/
• http://www.dreaminginflash.com/2008/05/21/interview-with-rob-bateman-away3d/

..and here’s the little summary:

1. Features such as native 3D APIs won’t affect both engines because they’re based on drawing triangles (skewing)
2. Otherwise, new drawing APIs will strongly improve both engines performances, vectors of drawTriangle instruction will replace arrays of very long drawing instructions
3. PixelBender will enhace shaders’ performances, Ralph talks about 10 times faster… Both are quite sure this technology will be used on shaders.
4. Both are assuming it would be great (but not a priority) to implement vector render (as Five3D already does)

stay tuned,

1. Papervision team merged Great White and Effects branches, now effects are considered “stable” (as a beta can be ) and they’ve been included in the project core. There’s a plenty of synthax and logic changes but the result is pretty awesome, so update your working copy from great white svn and visit Zupko’s blog to keep you up to date. Note for devs: From now on “effects” branch on svn is to be considered deprecated.
2. Alternativa Platform is ready to try!!!!! From Russia with love, this cutting edge 3D project finally is available for download and test. The major interest for me is to try out a 3d engine already cooked for flash player 10. Anyway keep calm your blood, whilst Alternativa is a really kickin ass project it’s not free nor open, so if you’re already planning to build up something that will be commercial you have to send some roubles there in Russia

…no doubts about this is a good way to begin summer time

Carlos & co put online dev.papervision3d.org , ie: what every wannabe pv3d developer was waiting for

This new blog section is to be intended as a melting pot of pv3d tutorials\working projects and job offers.
stay tuned!:D

Got pics? Send me the link so we can build up one big album!

So…have a nice trip on your spaceship!
