34<H2>Description</H2>
35<P>This function gets the current viewport parameters and places them in array <SPAN class="argument">vp</SPAN>.</P>
36<P>The <A href="GXSetViewportv.html"><CODE>GXSetViewportv</CODE></A> function sets the viewport in vector form. The order of parameters in <SPAN class="argument">vp</SPAN> corresponds to the order of parameters in the <A href="GXSetViewport.html"><CODE>GXSetViewport</CODE></A> function. The array returned by <a href="GXGetViewportv.html"><code>GXGetViewportv</code></a> can be supplied as an argument to <a href="GXProject.html"><code>GXProject</code></a>.</P>
37
38<H2>Examples</H2>
39<P><code>f32 vp[GX_VIEWPORT_SZ];<br> <br> <a href="GXGetViewportv.html">GXGetViewPortv</a>( vp );<br> vp[2] = 512.0f; // change width to 512<br> <a href="GXSetViewportv.html">GXSetViewportv</a>( vp );</code></P>
40<P>The viewport is typically set using parameters derived from the current render mode. For more information, see <a href="../Framebuffer/RenderMode.html"><code>Render Modes</code></a>.</P>
