An apparatus and a method for determining a Channel Quality Indicator (CQI) using a beamforming in a multi-antenna system are provided. A transmitter for determining a CQI based at least partly upon the beamforming in the multi-antenna system includes a beam former for distinguishing frequency tone intervals having a constant channel across an entire frequency tone, forming a beam by multiplying frequency tones of the frequency tone interval having the constant channel by different beamforming weights, and transmitting a preamble signal. Hence, the users can be scheduled based at least partly upon the beamforming gain, and throughput can be enhanced through the practical MCS selection.

A graphic processing method may include clipping a first polygon with a near plane of a view volume to create a second polygon, clipping the second polygon with a far plane of the view volume to create a third polygon, and/or discriminating if a homogeneous coordinate of the third polygon is 0. The third polygon may be clipped to one of left, right, top, and bottom planes of the view volume if the homogeneous coordinate of the third polygon is 0.
