<p>
Renders a quad.
</p>
<pre>
void Gfx_RenderQuad(
  hgeQuad *<i><b>quad</b></i>
);
</pre>
<h2>Parameters</h2>
<dl>
<dt><i>quad</i>
<dd>Pointer to a <a href="hgedata_quad.html">hgeQuad</a> structure, describing the quad to be rendered.
</dl>
<h2>Remarks</h2>
<p>
<b>Gfx_RenderQuad</b> function must be called between the <a href="hgefunc_gfxbeginscene.html">Gfx_BeginScene</a> and
<a href="hgefunc_gfxendscene.html">Gfx_EndScene</a> calls.
<br><br>
Quad is the basic <b>HGE</b> graphic primitive. See <a href="hgedata_quad.html">Quad structure</a> section
for more information about quads.
<br><br>
For performance reasons <b>Gfx_RenderQuad</b> accumulates consecutive quads
with the same texture and blending mode and then renders them with a
single call to <b>DirectX</b>.
In most cases you will not see any difference and don't have to deal with this
batching at all. But to be sure and safe it is recommended to group your
<b>Gfx_RenderQuad</b> calls by texture and blending mode.
</p>
<h2>Requirements</h2>

<b>Header:</b> hge.h<br>
<b>Import library:</b> hge.lib
