andengine – Android 2D Open GL ES Game Engine Similar to cocos2d-iphone for iOS

Media_httpi81photobuc_iexkw
A sweet engine for getting started with Android game development is the andengine 2D OpenGL ES engine. This is very simple and compares with cocos2d-iphone for iOS development in 2D with OpenGL ES.  They both support a wide range of 2d techniques with an OpenGL renderer.  Some great videos are posted on the andengine google code page showing a box2D example, multiplayer example and more.

Mobile games are on slower hardware, similar to later 90′s computers so native is a great way to go for 3d and 2d game development because of this limitation at the current time and well into the next few years.  Take this time to learn you some native gamedev. andengine isn’t native directly as it is Java based but compiled with the Dalvik JIT virtual machine. Another way to go native on Android is the Android NDK which allows C and C++.

The engine also has extensions that can be easily added and some great ones exist already.

Google Chooses WebGL and Moves O3D to a WebGL Javascript Library

Media_httpi81photobuc_cfssc
Google has decided to put weight behind WebGL and stop actively developing O3D as a plugin, rather they will make O3D a Javascript library on top of WebGL. This will focus the 3D plugin development efforts from Google into just WebGL on top of the OpenGL ES 2 spec, which in turn runs in the html5 <canvas> tag.

WebGL is pretty exciting offering browser based OpenGL and hardware rendered graphics. When this becomes mainstream this will change up gaming and interactive on the web immensely. Unity 3D and Flash 3d engines add lots of immersive environments and WebGL will be just as exciting, if all browsers adopt it (canvas/webgl).

At Google, we’re deeply committed to implementing and advancing standards, so as of today, the O3D project is changing direction, evolving from its current plug-in implementation into a JavaScript library that runs on top of WebGL. Users and developers will still be able to download the O3D plug-in and source code for at least one year, but other than a maintenance release, we plan to stop developing O3D as a plug-in and focus on improving WebGL and O3D as a JavaScript library.

About WebGL

Media_httpi81photobuc_ygdec
WebGL is a cross-platform, royalty-free web standard for a low-level 3D graphics API based on OpenGL ES 2.0, exposed through the  Canvas element as  interfaces. Developers familiar with OpenGL ES 2.0 will recognize WebGL as a Shader-based API using GLSL, with constructs that are semantically similar to those of the underlying OpenGL ES 2.0 API. It stays very close to the OpenGL ES 2.0 specification, with some concessions made for what developers expect out of memory-managed languages such as JavaScript.

WebGL brings plugin-free 3D to the web, implemented right into the browser. Major browser vendors Apple (Safari), Google (Chrome), Mozilla (Firefox), and Opera (Opera) are members of the WebGL Working Group. “It feels like, someone’s missin-ing”

Unity for Web Interactives Kicked Up A Notch By Carlos Ulloa/HelloEnjoy

Media_httpi81photobuc_qyehi

If the question is if Unity can do interactives as smooth and stylish as Flash I think you may soon find out.  Carlos Ulloa of Papervision 3D fame has kicked it up a notch in Unity 3D with this interactive very reminiscent of the Ford Focus demo that helped bring in Papervision 3D for flash in style. Gotta say though a mini is much better than a Ford Focus.

Flash is still the leader in web interactives and even marketing interactive 3d, Unity largely replaced Director and tools like it and high-end hardware rendered required interactives and games. This interactive by HelloEnjoy has loads of polygons, unity physics system, lighting, environment mapping, showroom cameras, reflection, skid decals, highly detailed mesh and more.  Just take a peek inside the vehicle and at the rims for the detail that is impossible with the 2000 poly limit of Flash 3D software rendered engines.

Web interactives this heavy aren’t doable in a non hardware rendered player like Flash.  Unity is looking to pretty much own this level of quality in a browser.  I don’t think I have seen another interactive looking this good with Unity 3D.

Unity still is lacking many features that Flash has in support of making interactives for the web such as webcam support, mic support, better video support, better gui system, html support (although flash barely) and a larger install base but Unity could easily take the high-end advertising market in addition to owning highly immersive games that need hardware rendering which it is already doing for web gaming.  It is 2010 soon, most computers have a decent video card.  Put them to use!
