Away3D Forum Ant example (Basic

The Away3D 4 Beta examples have one of an ant, with various lighting effects (the class is called Basic_Load3DS.as).

Has anyone been successful getting that to run on iOS? (specifically an iPad 2). I have no problems rendering it locally in the browser, but it shows a big blank space on the screen when I render to AIR 3.2. (I see the Away3D logo and the FPS profiler - but no 3D model)

If anyone’s been successful, I’d love to hear what you did. Thanks!

I’m getting an error when I run that same example in debug mode, so you may be seeing the same problem.

I have the ant running on iOS - specifically the ipad2 - runs fairly smooth.

the shadowmethod is the bad guy.
It runs on my test iphone 3gs, xoom android, htc desire and newer HD version.

if you add one directional lights: depending on screen res frame rate drops, on iphone 30 fps, with maps 512 for plane (diffuse and normalmap) and 256 for ant. +- 25 to 30 on others.

if shadowMethod is set, even with tight far plane set, it doesn’t start on iphone (blanck screen), crawls at 2/3 fps on xoom, 8 fps on HD desire.

I haven’t tried yet on IPad 2.

So if I take the shadow out it should work? I’ll try this out some more when I get to my dev machine. Can you take a moment and look at the error I posted? Why is the ant demo getting a null reference error?

So I removed all shadows and lights so it just shows the model and the ground plane. I can now load this on my iPad 1 and it shows as 30 fps.

However…

When I try and rotate the model, I am still getting the error in RenderableMergeSort.as on line 74. I can reproduce the 100% of the time.

One thing I would do first, is to add an addedToStage event before do anything.
Also I do not use loaders in my version but Prefab’s AS3 outputs. Will run some tests (this exact class) to see if I get same error.

Dear Administrator,

I encountered the same problem. I am using the “BasicLoad3DS.as” code from the Away3D 4 Beta example. I have the ant running. But when I upload another 3ds file, it does not show any thing. The top left corner of the result screen shows that “Poly: 11274”. So I assume it is reading the file. But nothing is shown.

I tried to remove all the shadows and lights. And no change. I load the 3ds file in Prelab. It works. I attached the following obj file. Could you please take a look at it? Thanks a lot.

Will this work on iPad, the original old the first version. My friend Emma Jewell Howard of Ipad case design store, are always looking on this guide but don’t have specific formula how this one work.
