<div class="descr"> <a name="details"></a>
<p>The <i>Hello Vulkan Cubes Example</i> shows more advanced usage of <a href="qvulkanwindow.html">QVulkanWindow</a>.</p>
<p class="centerAlign"><img src="images/hellovulkancubes.png" alt="" /></p><p>In this example there is a mesh loaded from a file and two different materials and corresponding graphics pipelines. The rounded cubes are drawn using instancing and feature a Phong lighting model with a single directional light.</p>
<p>Unlike hellovulkantexture and hellovulkantriangle, the uniform buffer handling takes an alternative approach here: dynamic uniform buffers are used instead of multiple descriptor sets.</p>
<p>The example requires QtConcurrent since it demonstrates simple usage of QtConcurrent::run(), <a href="../qtcore/qfuture.html">QFuture</a>, and <a href="../qtcore/qfuturewatcher.html">QFutureWatcher</a> in combination of <a href="qvulkanwindow.html">QVulkanWindow</a>. Mesh and shader data loading, the potentially expensive graphics pipeline construction, and the building of the frame command buffer are all done in separate worker threads.</p>
<p>The scene is embedded into a widget-based user interface. The <a href="qvulkanwindow.html">QVulkanWindow</a> subclass handles mouse and keyboard input as well since it provides a first-person style camera in order to allow moving around in the scene.</p>
