vkwc

A Vulkan-based wayland compositor with the ability to arbitrarily rotate and translate windows in 3D.

Dependencies

NOTE: This is highly unstable software! I really don't recommend trying it yet.

• The physics simulation is incredibly resource-intensive and may bog down your machine
• Xwayland is only partially supported
• The terminal emulator is hard-coded to foot
• Only one monitor is supported
• Spawning more than three windows will grind the physics sim to a halt
• Resizing and moving is disabled to give the physics sim control

A few people have asked anyway, however, so here are the dependencies I use to compile it on Gentoo:

dev-libs/wayland-1.21.0
dev-libs/wayland-protocols-1.28
x11-base/xwayland-22.1.5
dev-util/vulkan-headers-1.3.224
dev-util/vulkan-tools-1.3.224
media-libs/vulkan-layers-1.3.224
media-libs/vulkan-loader-1.3.224
gui-libs/wlroots-0.15.1-r1
dev-util/glslang-1.3.224-r1
gui-apps/foot-1.13.1

Additionally, you'll need to install cglm, which isn't available in the Gentoo repos. You'll also need meson and ninja.

Building

$ meson build/
$ ninja -C build

An executable called vkwc will be created in build/. Feel free to raise an issue if this doesn't work.

Usage

I highly recommend running vkwc nested a more stable compositor like Sway. If you run this in its own TTY, it may hang up and you will have to force-shutdown your device.

• Use ./vkwc -s <program> to execute program upon startup
• Alt+Esc exits
• Alt+F2 runs foot, a Wayland-native terminal emulator
• Alt+R cycles between displaying three buffers: color, depth and UV
• New windows spawn centered where the mouse is - use this if you want to stack things in a particular way

By default, a physics simulation is connected to the compositor, so windows should pile on top of each other somewhat realistically.

Good luck!
