No. There is no buffer - its already been submitted to the GPU at startup. The render mainloop looks something like: gl2::bind_buffer(gl2::ARRAY_BUFFER, vertex_buffer_id);
gl2::bind_buffer(gl2::ELEMENT_ARRAY_BUFFER, element_buffer_id);
gl2::draw_elements(gl2::TRIANGLE_STRIP, count, gl2::UNSIGNED_SHORT, None);(Actual example in robn/rust-hello-gl) |
