    Re: Algorithm of OpenGL tessellator

    OpenGL is not open-source. OpenGL is API specification open to anybody.
    Currently tesselation in OpenGL is available only as vendor specific extension AMD_vertex_shader_tesselator.

    Re: Question about VAO and GL 3.2 core

    Yes, VAO is in 3.2 core. It is even in 3.0 forward compatible context.

    Yes, draw functions can run without VAO. On pre-GL3 core/fc versions you can use display lists to simulate VAO's.
  8. Re: does nvidia's CG work with non-nvidia cards?

    Cg supports bacend for generation shader in GLSL language. And ATI supports GLSL in OpenGL (it is in OpenGL core since verion 2.0). So yes - Cg supports ATI card.

    Re: doubt in glList

    You don't need to delete old display lists to create new one's. Just call glGenLists function again to generate new lists and you can use them additionally together with previously created lists.

    Re: Render To Vertex Array (R2VA)

    Don't use NV extension.
    Use EXT_transform_feedback. It is based on NV extension, but is supported also by ATI, and it is also in GL3 core.
