public static IntBuffer newIntBuffer(int numElements)

newByteBuffer

copyFloatBuffer

public static FloatBuffer copyFloatBuffer(FloatBuffer orig)

bufferOffset

public static ByteBuffer bufferOffset(int offset)

Creates an "offset buffer" for use with the ARB_vertex_buffer_object extension. The resulting Buffers are suitable for use with routines such as glVertexPointer when used in conjunction with that extension. They have no capacity and are not suitable for passing to OpenGL routines that do not support buffer offsets, or to non-OpenGL routines.
