<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="q3dsurface.html">Q3DSurface</a> class provides methods for rendering 3D surface plots.</p>
<p>This class enables developers to render 3D surface plots and to view them by rotating the scene freely. The visual properties of the surface such as draw mode and shading can be controlled via <a href="qsurface3dseries.html">QSurface3DSeries</a>.</p>
<p>The <a href="q3dsurface.html">Q3DSurface</a> supports selection by showing a highlighted ball on the data point where the user has clicked with left mouse button (when default input handler is in use) or selected via <a href="qsurface3dseries.html">QSurface3DSeries</a>. The selection pointer is accompanied with a label which in default case shows the value of the data point and the coordinates of the point.</p>
<p>The value range and the label format shown on the axis can be controlled through <a href="qvalue3daxis.html">QValue3DAxis</a>.</p>
<p>To rotate the graph, hold down the right mouse button and move the mouse. Zooming is done using mouse wheel. Both assume the default input handler is in use.</p>
<p>If no axes are set explicitly to <a href="q3dsurface.html">Q3DSurface</a>, temporary default axes with no labels are created. These default axes can be modified via axis accessors, but as soon any axis is set explicitly for the orientation, the default axis for that orientation is destroyed.</p>
<a name="how-to-construct-a-minimal-q3dsurface-graph"></a>
<h3 id="how-to-construct-a-minimal-q3dsurface-graph">How to construct a minimal Q3DSurface graph</h3>
<p>First, construct <a href="q3dsurface.html">Q3DSurface</a>. Since we are running the graph as top level window in this example, we need to clear the <code>Qt::FramelessWindowHint</code> flag, which gets set by default:</p>
<pre class="cpp">
<span class="type"><a href="q3dsurface.html#Q3DSurface">Q3DSurface</a></span> surface;
surface<span class="operator">.</span>setFlags(surface<span class="operator">.</span>flags() <span class="operator">^</span> <span class="type">Qt</span><span class="operator">::</span>FramelessWindowHint);
</pre>
<p>Now <a href="q3dsurface.html">Q3DSurface</a> is ready to receive data to be rendered. Create data elements to receive values:</p>
<pre class="cpp">
<span class="type"><a href="qsurfacedataproxy.html#QSurfaceDataArray-typedef">QSurfaceDataArray</a></span> <span class="operator">*</span>data <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qsurfacedataproxy.html#QSurfaceDataArray-typedef">QSurfaceDataArray</a></span>;
<span class="type"><a href="qsurfacedataproxy.html#QSurfaceDataRow-typedef">QSurfaceDataRow</a></span> <span class="operator">*</span>dataRow1 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qsurfacedataproxy.html#QSurfaceDataRow-typedef">QSurfaceDataRow</a></span>;
<span class="type"><a href="qsurfacedataproxy.html#QSurfaceDataRow-typedef">QSurfaceDataRow</a></span> <span class="operator">*</span>dataRow2 <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qsurfacedataproxy.html#QSurfaceDataRow-typedef">QSurfaceDataRow</a></span>;
</pre>
<p>First feed the data to the row elements and then add their pointers to the data element:</p>
<pre class="cpp">
<span class="operator">*</span>dataRow1 <span class="operator"><</span><span class="operator"><</span> QVector3D(<span class="number">0.0f</span><span class="operator">,</span> <span class="number">0.1f</span><span class="operator">,</span> <span class="number">0.5f</span>) <span class="operator"><</span><span class="operator"><</span> QVector3D(<span class="number">1.0f</span><span class="operator">,</span> <span class="number">0.5f</span><span class="operator">,</span> <span class="number">0.5f</span>);

<span class="operator">*</span>data <span class="operator"><</span><span class="operator"><</span> dataRow1 <span class="operator"><</span><span class="operator"><</span> dataRow2;
</pre>
<p>Create a new series and set data to it:</p>
<pre class="cpp">
QSurface3DSeries <span class="operator">*</span>series <span class="operator">=</span> <span class="keyword">new</span> QSurface3DSeries;
series<span class="operator">-</span><span class="operator">></span>dataProxy()<span class="operator">-</span><span class="operator">></span>resetArray(data);
surface<span class="operator">.</span>addSeries(series);
</pre>
<p>Finally you will need to set it visible:</p>
<pre class="cpp">
surface<span class="operator">.</span>show();
</pre>

<p>And this is what those few lines of code produce:</p>
<p class="centerAlign"><img src="images/q3dsurface-minimal.png" alt="" /></p><p>The scene can be rotated, zoomed into, and a surface point can be selected to view its position, but no other interaction is included in this minimal code example.

<h3 class="fn" id="flipHorizontalGrid-prop"><a name="flipHorizontalGrid-prop"></a><span class="name">flipHorizontalGrid</span> : <span class="type">bool</span></h3>
<p>This property holds whether the horizontal axis grid is displayed on top of the graph rather than on the bottom.</p>
<p>In some use cases the horizontal axis grid is mostly covered by the surface, so it can be more useful to display the horizontal axis grid on top of the graph rather than on the bottom. A typical use case for this is showing 2D spectrograms using orthoGraphic projection with a top-down viewpoint.</p>
<p>If <code>false</code>, the horizontal axis grid and labels are drawn on the horizontal background of the graph. If <code>true</code>, the horizontal axis grid and labels are drawn on the opposite side of the graph from the horizontal background. Defaults to <code>false</code>.</p>

<p>Adds the <i>series</i> to the graph. A graph can contain multiple series, but has only one set of axes. If the newly added series has specified a selected item, it will be highlighted and any existing selection will be cleared. Only one added series can have an active selection.</p>
