I need to convert a CAD drawing of a product into a form that is usable by Papervision3D (or an equivalent 3D engine) in the Flash Player.
Are there any tools that do this? I understand that the Collada DAE format is supported in Papervision3D, but I don't know what steps/tools are involved (export directly from AutoCAD?).
I'm working on an Augmented Reality project that requires an animated 3d model to be displayed. I've managed to far to get all the AR marker detection and whatnot working, but I've come to a dead halt when trying to load an animated model. I'm working in 3Ds Max 2011 for all the modeling and animating. The model is exported as COLLADA (using 3dsMax's own Autodesk Collada exporter) and embedded into the Flex project. I can export a model, and it does load into papervision...The problem is that an animated model, although it exports fine and produces no compile-time erros, gives me a run-time error about a call to a null object. This error is being thrown by papervision's animation classes but it really doesn't give too much information, I see no animations...
This is the error I get:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

I have a DAE model that is parsed into several parts. I am able to deal with them separately, such as changing their material or colour but I am having problems adding click or hover listeners over the children. For example, lets say I have a model of a kitty where each facial feature is a child. I want to be able to hover or click the features and have a window pop up explaining the feature. I've tried parsing the model and adding listeners but it doesn't seem to work.
View 1 RepliesI have a client who wants some things in Papervision that I'm not sure how to do, namely: when the user clicks somewhere on a model, zoom the camera into that point.
I would use a tween engine to tween the camera forward, but as moveForward is a method, I'm not sure how I'd enter this data into a tweening call.
ActionScript Code:
Tweenlite.to(camera, 1, {??????});
Second, I need to set the camera to lookAt wherever the user clicked on the model. How can I tell what the closest vertex is next to the mouse click?
Is there a way for me to convert a 3D model (.dae or .3ds) into a swf movie that you can orbit around it, like when you view a 3D model in photoshop using flash.
View 5 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);
[Code]....
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.
As it is said here: [URL] "If you do a Google search today for "MVVM and Flex", the first post is by somebody who claims that MVVM is not a good fit for Flex. I couldn't disagree more. Out of the box, the Flex framework makes it much easier to implement a Presentation Model than similar MVVM implementations in Silverlight. That is not to say that there aren't good third-party libraries that make it easier in Silverlight, but without any help, it is easier to do in Flex." So MVVM as LOGICAL CONCEPT can be implemented in both but the way it is implemented in Silverlight requires more Plumbing than Flex.
What prevents Silverlight MVVM to be implemented like Flex ? Doesn't Silverlight have same capability in event system to do the same? If yes why does Silverlight do things more complicated what's the advantages then ? Is it about using Class Interfaces which are more strongly typed? What are the disadvantages also ? For example as for implementing MULTIPLE VIEWS for 1 View-Model does Flex implementation make it also more obvious?
I've been asked to create a model of an airport. Very basic. No textures and only simple shapes to represent check in zones, stairs, restaurants etc. It needs to be able to animate from floor to floor in birds eye view and to the outside of the building at an eye level view. It will be an annotated clip that plays following a persons movements. It needs to be incorporated into an adobe air application. I'm not sure even what software i should use for this. bear in mind i don't have any experience with 3D packages like 3DS Max. I suppose its possible in Flash Professional but can imagine drawing it all being a bit of a pain, is there something out there more suited?
View 7 RepliesI would like to make some kind of interactive 3D model in flash.
In the image below you see a 3D model. It's just an example to explain what I have in mind. You see a red disc 1, a blue disc 2 and a pushbutton. The idea is that the blue disc rotates (for example 45 degrees) compared to the red disc when you push the button. Is that possible in a 3D model that you also can turn around with your mouse?
I can make the models in Rhinoceros 4.0, that's no problem. Importing the model into flash is also no problem (papervision). But how can I add some interactives to the 3D model like a pushbutton and a slidecard?
There are some open SDK for Flash, that could be done. Rotating photos with physics? Examples of such programs BumTop, ePic, Coloris (no physics). The photo on the plane, it can be moved to the real physics?
View 1 RepliesI have a Collada (.dae) file that I found on Google's 3d Warehouse. Using Away3d, I'm able to load the file and display it on my view using the following code:
var object3d = Collada.parse(FooXML, { material:"white", x:0, y:0, z:0 });
view.scene.addChild(object3d);
The problem is that it's just floating out in space and no matter how I adjust the position via .x, .y, or .z, it never moves from its spot. I'm using Flash cs4 and the latest stable release from Away3d.
I have an SWF loading in an SWF containing a papervision scene.I've done it before yet problem is, I get an error - I'm not sure what the issue really is.[code]
View 3 RepliesI want to show a box in 3d on my website, and I was thinking to do it in Flash. How I can show a 3d model?I need something very simple, it's a textured cube, no interaction required, just let the user pan and zoom.There is a 3ds viewer in flash or something like that?
View 2 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?

View 1 RepliesIn CSS, we have a box model to define how border, margin, padding, and fill contribute to the total width and height of a rectangle. I'm porting some of my HTML/CSS design into Flash and can't quite figure out what Flash's box model is. In Flash, I've created a rectangle with gradient fill and a non-scaling 1 pixel stroke. I'm trying to get pixel-perfect positioning and sizing, but the experience has been unpredictable. I'm not really seeing a pattern to the following questions. The answer really changes depending on the exact circumstances.
When you set x and y both to be 0, where does the border lay? Is it off the screen? Is it being cut in half by the origin? Or is it completely visible?When you set width to 100, is the fill 98 wide or 100 wide?What happens to the 1px thick border when the rectangle is not positioned at whole number coordinates?
Example:
var sh:Shape = new Shape();
sh.graphics.lineStyle(1.0, 0x00FF00, 1.0, false, LineScaleMode.NONE);
sh.graphics.beginFill(0xFF0000, 1.0);
sh.graphics.drawRect(0, 0, 100, 100);
[code]....
I tried to create a 100x100 square at x:10, y:10. When I measured the total width and height in Photoshop, it came out to be 101x101.One would either expect the final dimensions to be 100x100 (border on inside) or 102x102 (border on outside).
there's a simple thing in papervision I can't do , I want to have a simple button on my swf like we have in flash , just a 2d square which is on screen and you can click on it and have some action
View 1 RepliesI keep trying to get started with Papervision, but I must be entering the classpath incorrectly as I keep getting errors that the compiler cannot find the classes.Is there some kind of bug with setting the classpath on a mac?I checked out the papervision stuff so it sits in:
/Applications/Adobe Flash CS 5/Papervision/as3/trunk/src/
Inside the src folder is a folder called "org", which contains "papervision3d" and the folders of classes.To set the classpath, I've gone to Preferences, chosen ActionScript, clicked on the ActionScript 3.0 button at the bottom, clicked the plus sign, and then clicked on the little folder button to add a path to the Library box (the middle box). I browsed and selected:
/Applications/Adobe Flash CS 5/Papervision/as3/trunk/src/
I thought at this point (after quitting and restarting Flash) that if I created a class file that had, for example,
import org.papervision3d.cameras.*
that it would work -- but it doesn't. It only works if I save the .fla and .as files themselves in /Applications/Adobe Flash CS 5/Papervision/as3/trunk/src/, in the same folder as the "org" folder. And I guess this means that the path in the Preferences setting is useless.
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.

View 1 RepliesI'm doing a project using FLARManager augmented reality and the Papervision3D library. Unfortunately, Papervision is giving me a lot of problems.My scene3D contains a DAE model and a plane. The plane has a MovieMaterial and is playing a video through FLVPlayback. The DAE and the plane are both inside the same DisplayObject3D container. FLARManager transforms the container so that everything appears through the angle of the marker.
My DAE model is a TV, the screen of the TV is transparent. I want to have my Plane inside of my DAE model, so that the Movie playing on the plane material appears to be what is playing on the TV.The problem is that, even if the plane has a lower Z index then the TV, it always appears in front of the TV.
How do I have my plane and its MovieMaterial appear behind the TV, so that some of its corners are cut out by the TV and the part of the TV thats transparent let me see the Movie? If its impossible, anyone has an idea of how I could get the desired effect of having a movie play on the screen of my DAE tv model?
im very new at papervision3d, i know in order to display a .DAE model i use this
[Code]...
But how can i do in order to use VRML models (.WRL).
I'm using BasicView to setup my PV3D scene, and the scene itself works fine (3d carousel of movie posters) but the InteractiveScene3DEvent is not firing when a poster is clicked or moused over. I set my viewport to interactive... twice.
view = new BasicView(stage.stageWidth,stage.stageHeight,true,true);
view.viewport.buttonMode = true;
view.viewport.interactive = true;
And here is the part of the loop where it the event listener is added.
var mm:filmsPoster = new filmsPoster();
mm.loadIMG(image);
var mat:MovieMaterial = new MovieMaterial(mm);
mat.interactive = true;
mat.animated = true;
mat.smooth = true;
mat.doubleSided = true;
mat.name = filmName;
mat.addEventListener(InteractiveScene3DEvent.OBJECT_CLICK, posterClick);
I'm new to papervision 3d and I created two display objects in basic view.
Here's a part of the code :
...
_stick = new Cube(materials, 50, 5, 500);
_ball = new Sphere(new ColorMaterial(0xfc0000), 80);
In the onRenderTick method, I tried to check whether two objects are hitted
[Code]...
However, stick.hitTestObject always returns false even if the stick really hits the ball as I see in the flash.
I am using Papervision3D Flash 3D engine to render a model. Also I am noob in 3D =D Model is simple, it's a parallelepiped with different textures on its sides. All works just fine except one thing: whenever I change my visual angle to a model from 90° textures on the sides are distorted. I notices that it is common effect in 3D graphics, I saw that effect in games and other 3D renderers (i.e. away3D, three.js) even wth different 3D models. Distorted texture on object (different view angle): Normal texture on object (same object and texture) (view angle == 90°): What is the reason of this effect?
View 1 RepliesDo flash 3D display engines such as Papervision allow data to be exported from the swf to a php back end and vice versa (PHP into model)? Does Unity allow for this?
If I was to build a simple 'change the colour of the model' application with a UI in a 3D package such as Papervision, could I then export the user choices to php or perhaps a javascript intermediary?
How to anti-alias a collada model in papervision3D?I've tried searching everywhere but didn't find any ways to anti-alias models. I've also tried blurring it a little as an anti-alias method but that only f-s it up and makes it look worse.How do I do that properly?
View 1 RepliesHow to correctly load an .md2 mesh description with Papervision 3D 2.1.932 ?
View 1 RepliesI feel like MVC misses a letter to describe the situation in a game. The model to me seems to consist of two distinct parts:
A group of vars that describe the current game state (these will have setters that send out events on change, and getters so that the view can access what changed)
The rules of the game that determine what happens once a certain input (i.e. shoot();) has been received by the controller (these will update the group of vars as deemed appropriate)
The view will exclusively be reading from 1 while the controller will be exclusively communicating with 2. This is why I make the distinction and want to divide them up into class1 and class2.
My questions:
I am unsure if I should be making this distinction, since I haven't seen it anywhere. If I should; should I make two separate classes, or should I extend class1 with class2? Finally, I am having trouble making sure that only class2 (and not the view) can change the variables in class1 (while still being able to send out an event when a value changes).
