I am looking for useful tips for reducing or removing triangle overlapping in Away3D.I already tried to increas segmentsW and segmentsH but it doesn't solve the problem.Here is a snapshot of my problem (The complex cubes are made of Plane objects, Maybe there is a better way to build the complex cubes ?)

I am building a website which loads some collada objects for each area. But I couldn't manage to clean the memory. It seems impossible to kill the objects.
I've found some samples implementing destroy() methods for away3d internal classes, but they're not working as well.
I use AS3's drawing api to draw filled shapes, but when they overlap, instead of filling the overlapped area, it becomes clear again, with no fill.
My question is, how can i get rid of this behavior, i need to just fill everything, is there a way to somehow "flatten" the shapes?
I am doing a project in which i need to slice an image into pieces. I could do the square slices easily using copypixel function over bitmapdata.
View 3 RepliesI'm building a small 3D engine for a game I'm working on. I've got my basics sorted: textured triangles with backface culling. However depth sorting is proving to be a difficult problem.I'm calculating the face Z by averaging out the 3 points that make up the triangular face. The longer faces sometimes overlap the smaller faces since they have a larger Z value and therefore rise up in the depth sorted display list.Is there a way I can use the area of the polygon to influence the depth sorting in any way? Or are there algorithms to accurately detect which triangle is above which triangle?
View 3 RepliesAt first I thought making tringles out of Polys was an easy concept. Considering I start with a quad of ABCD then I could convert this to two triangles of ABC and ADC, which is easy. However an alternate answer is BCD and BAD. The real differnce between the two outputs is exacerbrated when I now calculate the Normals for the two new faces. Also in some cases the edges break against the UV texture map in an undesirable way. Obviously in choosing the output faces I should be choosing the method as well that doesnt produce highly acute angles above all else. Unfortuantely I also have a number of pentagons and hexagons to render as well.
View 1 RepliesThis is a test program to measure the time it takes Flash to draw a triangle 10,000 times. The app (code below) calls runTimeTest() every N seconds which draws the triangle 10,000 times. Now for the "interesting" part: each call takes increasingly more processor until after about the 6th or 7th call it goes to "infinity" (see screen shot of TaskManager) Weird bug or explainable??

I'm trying to get a triangle to spin in place,
View 7 RepliesI am trying to achieve something similar to the flash movie in the below link. [URL]. As we drag the points of the triangle, the coordinates labels, ( A(1,2)) are properly aligned and arrange themselves so that they never collide with each other and never falls inside the triangle.
View 1 RepliesI am trying to calculate the top most intersection of an arbitrary number of planes, with no joy! I am using actionscript, but just need find an algorithm that i can implement.
Problem:
consider 3 vertical axis.The user enters 3 points for each triangle/plane such that the points of the triangle lie on one of the axis.The user can enter an arbitrary number of triangles I need to find the topmost layer of these triangles and display it on the screen as well as the coordinates of interection.
Here is a picture to clarify what I mean with 2 triangles:
However, when we allow for more than 2 triangles, I get awkward lines of intersection.
I'm not that familiar with AS3 but I got a script from someone where some objects are drawn.I want to add several triangles so that each triangle can be dragged on the stage.
Code:
package app.simpleShapes {
import flash.events.TUIO;// allows to connect to touchlib/tbeta

what's the main idea behind 3D in Flash. I mean, I've seen a lot of scripts to make rotating squares or triangles or whatever, but never managed to understand how they were made.

i have a small question concerning away3D. I have some cubes with the exact same dimensions that are positioned in the same place. When i click on the stack of cubes, i want to register a click on the cube i added last. Instead of doing this, the click is registered on the cube i added first.
I have found a way to alter the cubes position in the container and have tried putting the element at the end (code below) and start of the childrenArray, but nothing seems to work. I am kinda really stuck here, so if anyone knows how to get the top level element when clicking on the stack, i'd be happy to hear.

when I try to render a cube using Away3D + Molehill, I only get a white default screen, I followed the instructions here: hhe only thing I did not do, was the part that talks about the patch, cuz If I do that I get errors like when I try to import the Sprite class, for example.Im using FB 4.5.!

[URL]..why it's impossible to me to center the pivot of this container? if I do container3D.centerPivot() all my cubes are moved from they're position and still the pivot it's not in the center, but at the center of just ONE cube (the last on the bottom-right corner). How can I center the pivot of the container properly to ITS center?

What are the pros and cons of various Flash 3D engines with regards to performance on mobile devices? Which do you prefer -- which have you tried (examples of apps developed) implementing on mobile devices?
View 1 RepliesI'm working on a spherical movie viewer in Away3D & am having a problem when I apply a VideoMaterial texture to a 3D primitive. The video appears heavily pixellated, like it's being scaled or hugely compressed. When I apply a BitmapMaterial of a single still image from the video it appears fine, so I don't think the resolution of the video is the problem.
I found [this discussion][1] suggesting a solution by specifying the "fixedHeight" & "fixedWidth" when I call the constructor, but those arguements seem to have no effect, and I can't find them in the API either. I do see something called "lockH" & "lockW," [in the API][3], but I they don't seem to have any effect either.

I want to attach spheres to rotating sphere but I've encountered some rotation problems:
In application u can rotate mainSphere in both x and y axiss'.
If I rotate main sphere in only x axiss or only y axiss, it works correctly. But if I rotate main sphere around both x and y axiss, sphere is attacing the wrong place.
Here is the code:
ActionScript Code:
// these are the spheres containers. Sphere container class extends form object3d
var mainSphere:SphereContainer3D;
var attachingSphere:SphereContainer3D;

View 1 RepliesI have a question regarding my implementation of a collada 3d file. This is really my first venture into the realm of 3d and I've read some of the basic tutorials so I'm not 100% clueless, but I am a bit confused by what is appearing with the following class (this is a document root class, loaded by the .fla file): the images I loaded to skin the board with are showing up, but just in specific triangles. I want it to skin across the whole board. Is [code]there something special I need to do to achieve this?Also, my final goal with this project is to skin (texture map) one side of the board with a bitmap (drawn from an MC) and the other side with a different bitmap.

How to port Away3d scene with animation into PV3d? Are there any tutorials on how to do that?
View 1 RepliesSo I have some 3d points generator that gives points like
{1,1,1}
{1,2,3}

So I know that PV3d looks quite dead. But it is documented over the internet much better. So I decided to develope my product using old but good PV3d engine. Time goes on so I plan to port it sooner or later to Away3d. So I need a list of things that aere not in Away3d that I have in PV3d. And a list of generall use diffrencies (use of cameras, viewports, etc). So where to get comparing list of papervision3d vs Away3d?
