57<h2>Description</h2>
58    <div class="section">
59<p>Sets the clipping face planes. This function is an immediate function. (<I>Immediate functions</I> directly generate commands and insert them into the command buffer.)</p><p>There are four clipping plane coefficients (P1, P2, P3, P4) and the half space defined by the clipping planes must satisfy the following expression:<br /><CODE>P1 * x + P2 * y + P3 * z + P4 * w &gt;= 0 </CODE><br /><br />This is the format for the data inserted into the command buffer:<br /><CODE>0x00000000 Eq1 <br /> 0x00000004 [Reserved] <br /> 0x00000008 Eq2 <br /> 0x0000000c Eq3 <br /> 0x00000010 Eq4 <br /> 0x00000014 [Reserved] </CODE><br /><br /> <CODE>Eq1</CODE>, <CODE>Eq2</CODE>, <CODE>Eq3</CODE> and <CODE>Eq4</CODE> are 24-bit floating point values. They are obtained by converting P1, P2, P3, and P4.</p><p>The default value is all zeroes.</p></div>
