I’d like to draw a mesh with a big mesh (think ~120k vertices).
If I try to put all the vertices in a single index buffer it won’t work, because I’m using a java.nio.ShortBuffer as index buffer, so the max is 2^15 – 1, whereas I need ~2^17 vertices. Should I split my mesh in multiple pieces? Can I use other subclasses of Buffer as the fourth argument to GL10.glDrawElements?

    Massive Edit following miniBill comment !

    In fact, OpenGL-ES only supports GL_UNSIGNED_BYTE or GL_UNSIGNED_SHORT for indices.
    The most used is GL_UNSIGNED_SHORT which allows 2^16-1 vertices. The other types are only supported by OpenGL.


    You can also use GL_INTor GL_UNSIGNED_INT for indices, which, I suppose, you can store in a java.nio.IntBuffer.

    Looks like you’ll need to split your geometry.
