Tutorials and libraries for OpenGL-ES games on And

问题:

What tutorials and libraries are available which can help beginners to develop 2D and 3D games on Android using OpenGL-ES? I'm looking for tutorials which can help me learn OpenGL-ES, and I'm looking for OpenGL-ES libraries which can make life easier for beginners in OpenGL-ES.

Since Android is still small, I guess it may be help-full to read iPhone OpenGL-ES tutorials as well, as I suppose the OpenGL-ES functionality is much the same.

I have found the following useful information which I would have liked to share:

Android tutorials:

• DroidNova: Basic tutorial covering polygons, no textures
• anddev forum with some tutorials

Other Android OpenGL-ES information:

• Google IO lecture regarding games, not much OpenGLES
• The The Khronos Reference Manual is also relevant to have, but its not exactly the best place to start.

iPhone OpenGL-ES tutorials (where the OpenGl-ES information is probably useful):

• http://web.me.com/smaurice/AppleCoder/iPhone_OpenGL/Archive.html
• http://iphonedevelopment.blogspot.com/2009/05/opengl-es-from-ground-up-table-of.html

As for libraries which a beginner might use to get a simpler hands-on experience with OpenGL-ES, I have only found Rokon, which is recently started, thus has many holes and bugs. And it's gnuGPL licensed (at the moment) which means it cannot be used, if we wish to sell our games.

What else is out there?

回答1:

The site you mentioned is very good, but I think the best one I have found is by INsanityDesign. It is a port of the great OpenGL nehe tutorials. This is a great place to start, it gives you source at different levels that you can play with and change to see what different parts do. Other than that reading OpenGL documentation, will help as well. I am not great at the OpenGL stuff, but have been able to figure things out using the resources I mentioned.

An excelent tutorial about OpenGL ES 1.1 on Android:

You definitely can sell your games based on GPL software, read more here: http://www.gnu.org/philosophy/selling.html

回答4:

I gave up on anddev tutorials a long time ago. Every such tutorial I tried would not even build correctly, they were way out of date, and the guy who does them never seems to finish anything.

Unfortunately, the information you really want really is that scattered: you will not find it all at one URL unless you are willing to read the entire Red Book; but that is certainly no tutorial, it is a much more exhaustive reference.

Yet it seems that only such an exhaustive reference will give the information you need in a complete enough and precise enough form to understand such useful and basic issues as the distinction between viewing transformation, viewport transformation, model transformation and viewing transformation, and why OpenGL insists on combining the latter two.

There are some good OpenGL ES tutorials for Android here too: http://obviam.net/index.php/category/opengl/

回答6:

If you want to get started from a really basic OpenGL ES project on Android (one that's actually been compiled and works) you can have a look here: http://www.ruibm.com/?p=263

回答7:

There is good tutorial series for beginners,to learn opengl.

回答8:

The best resource I have found so far is Learn OpenGL ES. In fact I found it because it is recommended on NeHe. It's active and has a series of tutorials specifically for Android which are quite comprehensive.

An OpenGL ES tutorial series that I found immensely helpful while porting an iPhone game to Android using the NDK was:

回答10:

There is now a 3d library for android available called min3d:

I haven't used it yet, but it looks useful.
