OpenGL Separating Polygons Inside VBO - Stack Overflow

You can use primitive restart. The downside of this is that you need an index array, which may not have been necessary otherwise. Apart from that, it’s straightforward. You enable it with:
glPrimitiveRestartIndex(0xffff);
glEnable(GL_PRIMITIVE_RESTART);

You can use any index you want as the restart index, but it’s common policy to use the maximum possible index, which is 0xffff if you use indices of type GL_UNSIGNED_SHORT. If you use at least OpenGL 4.3, or OpenGL ES 3.0, you can also replace the above with:
glEnable(GL_PRIMITIVE_RESTART_FIXED_INDEX);

2
Then you set up an index array where you insert a 0xffff value at every position you want to start a new polygon, and bind the index array as usual. Then you can draw all the polygons with a single glDrawElements() call.
