<a name="running-the-example"></a>
<h2 id="running-the-example">Running the Example</h2>
<p>To run the example from Qt Creator, open the <b>Welcome</b> mode and select the example from <b>Examples</b>. For more information, visit Building and Running an Example.</p>

<h2 id="description">Description</h2>
<p>Advanced custom material example shows more complex shaders, and demonstrates controlling your shader properties with QtQuick user interface and Animation. Water is a 3D mesh, that is modeled and uv mapped inside Blender, and then brought into Scene 3D as an <code>.obj</code> file. Shader properties that user can control, are defined in <a href="qt3d-advancedcustommaterial-watermaterial-qml.html">WaterMaterial</a>.</p>
<a name="controls"></a>
<h2 id="controls">Controls</h2>
<a name="texture-scale-slider"></a>
<h3 >Texture scale slider</h3>
<p>Multiplies texture coordinates inside the vertex shader. Controls the size of the textures on water surface.</p>
<a name="texture-speed-slider"></a>
<h3 >Texture speed slider</h3>
<p>Offsets values for texture coordinates which are animated in <a href="qt3d-advancedcustommaterial-water-qml.html">Water.qml</a> and then passed to vertex shader. Creates the effect of textures scrolling over the surface.</p>
<a name="specularity"></a>
<h3 >Specularity</h3>
<p>Multiplies specular texture values inside fragment shader. Makes the water reflective.</p>
<a name="distortion"></a>
<h3 >Distortion</h3>
<p>Multiplies the offset in red and blue channels of wave texture in fragment shader. Makes the surface textures animate more randomly.</p>
<a name="normal-amount"></a>
<h3 >Normal amount</h3>
<p>Multiplies the normal map values inside fragment shader. Controls the visibility of smaller waves on the water surface.</p>
<a name="wave-speed"></a>
<h3 >Wave speed</h3>
<p>Modifies the frequency of the sine wave inside vertex shader. Controls the speed of the waves.</p>
<a name="wave-height"></a>
<h3 >Wave height</h3>
<p>Multiplies the vertex <code>Y</code> position inside vertex shader. Controls the height of the waves.</p>
<a name="mesh-rotation"></a>
<h3 >Mesh rotation</h3>
<p>Rotates the water mesh in <a href="qt3d-advancedcustommaterial-water-qml.html">Water.qml</a>.</p>
