<h2 id="details">Detailed Description</h2>
<p>The <a href="qsgvertexcolormaterial.html">QSGVertexColorMaterial</a> class provides a convenient way of rendering per-vertex colored geometry in the scene graph.</p>
<p><b>Warning:</b> This utility class is only functional when running with the OpenGL backend of the Qt Quick scenegraph.</p>
<p>The vertex color material will give each vertex in a geometry a color. Pixels between vertices will be linearly interpolated. The colors can contain transparency.</p>
<p>The geometry to be rendered with vertex color must have the following layout. Attribute position 0 must contain vertices. Attribute position 1 must contain colors, a tuple of 4 values with RGBA layout. Both floats in the range of 0 to 1 and unsigned bytes in the range 0 to 255 are valid for the color values.</p>
<p><b>Note: </b>The rendering pipeline expects pixels with premultiplied alpha.</p><p><a href="qsggeometry.html#defaultAttributes_ColoredPoint2D">QSGGeometry::defaultAttributes_ColoredPoint2D</a>() can be used to construct an attribute set that is compatible with this material.</p>
<p>The vertex color material respects both current opacity and current matrix when updating it's rendering state.</p>
