My opinion is: OpenGL - There is a huge body of documentation that have allowed me to do some small programs by myself. - It's cross plataforms, and there are free implementations of the interface. - There are projects that use it from managed frameworks such as Java and .NET, which allows to develop with it easily in languages different from C and C++. - Works well with SDL, which is also cross plataform and can be used from managed frameworks, so an stack such as Mono + SDL + OpenGL gives you a free cross plataform solution.
OpenCV - Is free and crossplatform. - Lacks the popularity and / or documentation body that allowed me to learn OpenGL by myself. - Is commonly used for image recognition, machine learning and related applications, this sets OpenCV as a higher level software. - I've found something about using it from Phyton (apart from C and C++), so a wrapper for Java or .NET should be possible. - Can anybody verify if OpenCV is able or not to create 3D images? because I suspect that (given my lack of knowledge about OpenCV) you shouldn't be putting OpenCV and OpenGL (and DirectX) in the same "bag". DirectX - Have good documentation, thanks to Microsoft that is always trying to bring developers his platform. - Have features for other stuff apart from 3D rendering (what OpenGL does), such as input from Joysticks, networking and 3D audio (somethin you may get with SDL + OpenGL + OpenAL). - Implementation as a free software is restricted due to legal implications, efectively constraining it's serius develop to Windows. So... if by 3D or image processing programming you mean taking a picture and analize it to create a 3D representation, then I think you are looking for OpenCV Buf it you mean to create 3D images to display on a computer screen on real time, then you are looking for OpenGL If you have sold your freedom, then DirectX If your situation is a mix of the above (for example for augmented reality), you could use a mix of the above. Hopes that helps. Alfonso J.
