Away3D Forum Loading image at runtime rather than embedding it

Loading image at runtime rather than embedding it Software: Away3D 4.x

Pokey, Newbie Posted: 27 May 2013 05:46 AM Total Posts: 23 Hello! I am trying to load an jpeg image that is larger than 2048 pixels on one dimension which I intend to crop using UV mapping. I cannot get AssetLoader to behave. Using the following code: `_loader = new AssetLoader(); _loader.load(new URLRequest('../assets/earthsurface2.jpg'));` gives me the error: Error #2032: Stream Error. URL: app:/assets/earthsurface2.jpg at away3d.loaders::AssetLoader/onRetrievalFailed()[/Users/pokey/Documents/Adobe Flash Builder 4.7/away3d-core-fp11_4_1_0_Alpha/src/away3d/loaders/AssetLoader.as:430] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at away3d.loaders.misc::SingleFileLoader/handleUrlLoaderError()[/Users/pokey/Documents/Adobe Flash Builder 4.7/away3d-core-fp11_4_1_0_Alpha/src/away3d/loaders/misc/SingleFileLoader.as:342] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at flash.net::URLLoader/onComplete() None of the examples show images loading at runtime, I am not even sure that AssetLoader is what I should be using. Any ideas anyone? TIA

Pokey, Newbie Posted: 27 May 2013 05:39 PM Total Posts: 23 [ # 2 ] Thank you, it seems AIR does not support “../”, putting the jpg in the src folder solved the issue. May I ask my next moronic question: What command do I use to convert the AssetLoaderToken into something the Cast.bitmapTexture() can use? I am sorry to be a bother, but I cannot find any example code that loads image data in this manner. TIA

Pokey, Newbie Posted: 28 May 2013 05:29 AM Total Posts: 23 [ # 4 ] I would like to use AssetLoader to keep the project as generic as possible in case I want to deploy it on some other platform later. I have managed to get this far: `//massive texture setup _loader = new AssetLoader(); _loader.load(new URLRequest('earthsurface2.jpg'),null,'hiresmap'); _loader.addEventListener(LoaderEvent.RESOURCE_COMPLETE, onSceneResourceComplete); _hiresmap = AssetLibraryBundle.getInstance().getAsset('hiresmap') as BitmapTexture;` `earthMaterial2 = new TextureMaterial( Cast.bitmapTexture( _hiresmap ) ); earthMaterial2.gloss = 5; earthMaterial2.lightPicker = _lightPicker;` and I am not getting any errors, but the globe shows as pure white. I have also tried scaling the UVs in case the texture was too hi res. Am I handling this properly or is there a better way? TIA
hjimage, Newbie Posted: 09 July 2013 09:44 AM Total Posts: 4 [ # 5 ] you must change the image formats before you load an image to the server which support the format. if it is a large one, you can crop images in vb.net with some software. make sure everything is not so complex.
