vkcubepp [options]

vkcubepp displays a spinning 3D cube rendered using the Vulkan graphics API. It's a simple test application to verify that Vulkan drivers and libraries are correctly installed and functioning.
Part of the Vulkan-Tools package from the Khronos Group, vkcubepp is written in C++ (vkcube is the C version). Both produce the same visual output but demonstrate different API usage patterns.
Running with --validate enables Vulkan validation layers, useful for developers debugging Vulkan applications. The cube should spin smoothly if Vulkan is working correctly.

--validate

Enable Vulkan validation layers.

Requires Vulkan-capable GPU and drivers. May fail silently if Vulkan is misconfigured. Part of vulkan-tools package. Window system support (X11/Wayland) depends on build options.

vkcubepp is part of the official Vulkan-Tools repository maintained by the Khronos Group. Vulkan was released in 2016 as a successor to OpenGL, providing lower-level GPU access. The cube demo serves as a minimal Vulkan test case.
