anyone actually successfully implement 3D object instancing with papervision 3d?and does it actually perform good enough to be used to instancing many copies of a single model (tress for example)?so far I failed to correctly display the instances and I doubt the performance benefit of doing this as papervision 3d is using software render.
View 1 RepliesI just wanted to check something if anyone can clarify this:
If I create an object with
Code:
And then replace it by doing
Code:
Does the original instance get deleted or will it remain in memory? If it does, how do I remove it properly?
I have a papervision camera of which turns using keyboard input, I have a radar of which I would like to orientate to direction when the camera turns.I have it all working apart from mapping my (camera) DisplayObject3D.rotationY to RadarInterface.rotation correctly.The camera (or any 3d object) works with values I'm finding hard:Clockwise: 0 to 89, 89 to 0, -0 to -89, -89 to -0 doing a complete 360.So if I were to turn 180 degrees I'd go from 0 to 90 and back down to 0 again.
View 1 RepliesI am trying to build a portfolio application similar to the used by Whitevoid. I am using Flex 4 and Papervision3D 2. I have everything working except for one issue. When I try to load an external SWF as a material on one of the planes, I can see any native Flex or Flash components in their correct positions, but the papervision objects are not being rendered properly. It looks like the viewport is not being set in the nested swf. I have posted my code for loading the swf below.
private function loadMovie(path:String=""):void
{
loader = new Loader();
request = new URLRequest(path);

Below I have posted two pictures. The first is a shot of the application running by itself. The second is the application as a MovieMaterial on a Plane. You can see how the button created as a spark object in the mxml stays in the correct position, but papervision sphere (which is rotating) is in the wrong location.
How do I get the 2D screen coordinates of a 3D object when using Papervision 2.0 (Great White)? I've read that following properties should return the screen coords but these always return 0.

My question is regarding the use of RTMP files (delivered via a Flash Media Server) and Papervision; specifically using an RTMP stream as a texture on a Papervision object. I've already developed a number of successful methods for applying progressive flv/f4v files to Papervision objects. The RTMP streams, however, have presented a number of obstacles.
I will bypass the myriad of research I've done looking into this issue and say that others have inquired about this as well - but from what I can tell, no solid answer or solution has been found - especially under Flash Player 10. So, here's what we have so far:
1. A Flash Media Server running on a University server.
2. A Papervision project

There's a part of as3 that i've not quite learned yet. maybe it's not good practice to do, but i'm trying to instance classes without having to specifically write their names in the code.In essence, i want to have a string containing the name of a class (in this case, "Pistol") and i want to be able to use that variable, to create an instance of that class. Presumably using new. I'm not exactly how to go about resolving a string into a classname though.

You can hook into the creation of Flex 4 item renderers easily enough (through itemRenderer, or itemRendererFunction) allowing you to pull renderers from a custom object pool, but how would you put those renderers back into the pool?
I understand that layout virtualization does a form of object pooling, but I'd like a way to hook in to that. For example, when an itemRendererFunction has been assigned to a data group with a virtualized layout, item renderer construction is indeed deferred, but the instances are not re-used - I'd like to be able to intervene there, if possible.
But even in the case of normal virtualized renderers (where the instances are re-cycled) it would still be useful to be able to manage the pool manually. Pools could be shared between data groups, for example, to reduce the initial buffer required to populate each group.
Is there any way to know when Flex discards an item renderer instance? I have a sinking feeling that there is just no reliable way to tell - even though perhaps there should be.
I wish to develop a softare for 3D object compression (by polygon reduction) in flex using papervision 3D. Could you please suggest me an efficient algorithm for the same?
View 1 RepliesI am using CS4 with AS 3.0... I want to implement both a freeware photo flash gallery and mp3 audio player that I found into my all-Flash website. Both of these require reading from an xml file to get their content. They both come with html embedding instructions, but I don't know about actionscript.
View 14 RepliesI asked this question in papervision 3d forums, but nobody replied. So. I am writing a 3D application with actionscript 3 and papervision 3D. But I have stuck on one problem, I can't figure out, how to place skidmarks (decals?) on an object. The only method I can think of is drawing directly to BitmapData (texture). What would you suggest to draw a textured skidmark on ground (plane primitive)?
View 1 RepliesI have done globe in papervision - basically sphere + material (image of political map) over it.Now, I need to make every country on my globe interactive, what means, I need somehow create event listeners for lots (at least 15) of small areas on my globe, and if I click those areas, something will happen (say, additional info windowwill come out)I googled a lot and found a lot of things describing some realted stuff (hotspots?), but since I am quite new in flash/actionscript/papervision, could I, please, get some introductory idea how my problem might be solved?

View 7 RepliesI am trying to develop a game based on papervision and flash.the very basic idea of the game is that some 3D objects are falling from the sky and you have to catch them .. At a time there can be as many as 20 of such 3D objects on the stage.Now the problem is that these 3D objects are causing too much CPU usage .. I was hoping if there was another way to do the same thing and which causes less of performance issues ...
1.I have two classes suppose A and B
2.the class A calls class B
3.class B initiates a 3D sphere whenever it is called .. the Sphere has a bitmap image material .. and it rotates along the X axis on every enter frame event
4.class A has a timer function which moves the 3D object in the Y direction and also destroys it when the object reaches a specified Y position ..here are the code snippets ...
Class A :Code:

how to setup Planes with papervision, then retrieve them later?I've set up the 3d scene like this:
PHP Code:
var con:Sprite = new Sprite();
con.x = this.width * 0.5;
con.y = this.height * 0.3;
holder.addChild(con);
[code]....
but none of these methods seem to work,, possibly because you can't do the same things to Planes that you can to movieclips...(?)the scene.numChildren seems to work though.
Has anyone seen rendering glitches with Papervision?
seee the flash movie at [URL].. which demonstrates the problem.

View 3 Repliesi created a 3d model using sketchup and exported it as a DAE file.
then i try to import the model into papervision, but the model never appear.
when i use the DAE file provided in the examples, it works. only when i tried to create my own models, it doesn't work. does this have anything to do with sketchup?
now i need to add a health bar and countdown timer on the screen. how am i going to do it? adding a plane in the 3d scene? the health bar is always on the top right corner of the screen. is there anyway of NOT using 3d concept to implement this. i mean i could do it with a plane keep changing it's texture to show the status of the character. is there any cleaner way of doing it?
