I want to know OpenGL Version that VTK 5.6.1 implement because I want to create android application that use vtk.I will use VTK visualize DICOM image and present them on screen.
I know Android OS implement OpenGL ES but I don’t know VTK 5.6.1 OpenGL version.if VTK OpenGL’s version is 4.1 that support OpenGL ES,it mean I can use vtk 5.6.1 to create android application,right.
Thanking you for assistance in advance.
This is highly related to your other question about using VTK on Android. As I said in response to that question, VTK does not currently support Android (or other embedded systems). The base OpenGL version used by much of VTK is 1.1, but quite a few of the classes test for various OpenGL extensions and use them optionally. Porting VTK to OpenGL ES (1.x or 2.0) is non-trivial, but some initial work has begun. See this post for a little more background.
I have been doing some work on the iOS and Android platforms, largely concerned with using OpenGL ES 2.0 from C++ on both platforms (NDK on Android). The results were promising, but it will take time to port a significant portion of VTK. OpenGL ES 2.0 and Open GL 2.1 are quite similar in their API, but they are not identical.
