What graphics engine Maya uses, OpenGL or DirectX? Does it at all use any? Since maya is written in C++.
For going deep into Maya, is it proper to learn to use OpenGL or one should go with DirectX?
My questions specially are associated with adding super new functionalities, such as new edge-system for a certain geometry in Maya.
What graphics engine Maya uses
Its own.
Neither OpenGL nor Direct3D are graphics engines. They're drawing APIs. You push in bunches of data and parameters and shaders to make sense of that data, and rasterized points, lines and triangles on a 2D framebuffer come out on the other side. That's it.
Maya, like every other graphics program out there implements its own engine or uses a graphics engine library that maybe uses Direct3D or OpenGL as a backend. In the case of Maya OpenGL is used for the interactive display. But the offline renderer is independent from that.

As long as you don't want to write lower-level-ish Maya plug-ins, you don't have to learn either.

You surely want to make that available to the offline renderer as well. As such neiter OpenGL nor Direct3D are of use for you. You have to implement this using the graphics pipeline functions offered by Maya and its renderer. Note that you might also have to patch into external renderers if you want to use those with your news edge features.

Does SDL2 have the capability to render things in 3D (i.e. make cubes, spheres, etc.) without the use of OpenGL, or does it only have 2D capabilities?
Your question would be better off on GameDev Stackexchange but to simply answer your question: SDL2 itself has no capabilities to render 3D objects. This is also stated in SDLs about page:
Simple DirectMedia Layer is a cross-platform development library designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D
SDL provides some functions to help you ease the use of OpenGL, but you'll have to learn and use OpenGL to allow rendering 2D and 3D vector graphics.
A good tutorial that I'd recommend on the basics of SDL is this site. It only has some chapters related to the use of OpenGL, but if you haven't used SDL much, this is a great start.
Here's what the wiki has to say:
2D Accelerated Rendering
For advanced functionality like particle effects or actual 3D you should use SDL's OpenGL/Direct3D support or one of the many available 3D engines.
SDL does not aim to provide a 3D API, but gives you some support for other well-known APIs like OpenGL and Direct3D.
Note that SDL2 also provides Vulkan support.
I my collage i have to do a assignment in opengl and they intimidate us to do that in pure opengl. What it is just simply create and shown a transparent cube and put table inside it all of the model must create by the program they can't import by other modeling software like blender, 3dmax etc. And also they expect very high level lighting atmosphere in that cube. I am new to side and i heard that SDL is a game engine.
I wonder if i use SDL in my assignment may i end up with zero mark if it is not contain opengl? If there is good way to do this simple task please let me know!
Well, SDL is not a game engine and it is not pure OpenGL. However, you can build pure OpenGL applications using the windowing API that SDL gives you. SDL is just one of many options for window management and GL context creation.
SDL can set up a window for you, can set up the OpenGL context, and handle user input. From there, you can write pure OpenGL and render your cube or whatever. If you have not used OpenGL or SDL before, then you probably have a lot of work ahead of you.
As another difference, SDL does have an additional 2D rendering API. If your assignment is to do 3D with OpenGL, then obviously DO NOT use this 2D API.
If I want a 3D animated/rigged character in OpenGL game how i would have it in OpenGL?If i make a animated/rigged character in 3Ds max is it possible to have that character in OpenGl?would be helpful if someone gives a proper way or a tutorial link to export animated model from 3d software to open GL
OpenGL is a very simple 3D framework which only offers the bare bones. OpenGL can display triangles and fill them with color and that's about it. It comes with some helper functions to manipulate point clouds but it's really very basic.
Animation and rigging are way beyond what it can do. What you need is a framework which supports animation and rigging which then uses OpenGL to display the result.
Since you don't specify any requirements, it's hard to say which one would be good for you. Blender is probably a good place to start. It's game engine runs on many platforms, supports OpenGL, animation and rigging.
I'm writing an OpenGL game, and want native looking GUI elements. I was wondering if anyone has successfully hacked GTK+ using GtkOffscreenWindow and gtk_offscreen_window_get_pixbuf to render to an OpenGL texture, and whether this would have reasonable performance, considering repeated re-uploading of texture data every time the GUI is updated
While this is certainly possible, I'd instead use a real OpenGL widget toolkit like Clutter. If you want to render GTK+ with OpenGL, I'd start by creating a new GDK backend (X11/OpenGL or something like that), that (re-)implements all the GDK drawing functions using OpenGL. A nice side effect would be, that all GTK+ windows would allow for ordinary OpenGL rendering, too, i.e. no more need for a GtkGLWidget class.
I have an application using OpenGL code. Now I want to convert it into JOGL code. Is it possible to convert OpenGL code to JOGL? What are the changes we have to do?
There are the famous suit of Nehe Tutorials for OpenGL, as mentioned above. The best part of this tutorial is that you can view JOGL and Ogl side by side. In Jogl you basically get a thin wrapper around OpenGL with Java syntax, garbage collection and all other libraries available. Making streaming objects and textures over the net and rendering them via OpenGL a breeze, you can also play around with shaders and perform array calculations faster in java using Jogl.
This tutorial might be handy. Basically you need to make all the OpenGL global function calls into calls on the proper object instance. This goes for constants too:
glBegin(GL_WHATEVER);
becomes
gl.glBegin(GL.GL_WHATEVER);
Most opengl functions are named the same in jogl and reside in the GL class. If you know opengl then it will be very easy for you to port it to jogl.
the first steps are:
GL gl = arg0.getGL();
GLU glu = arg0.getGLU();
Have a look at some tutorial on the web which will help you to get started.
