Flip3DComp

DirectComposition Flip3D switcher. A faster, more complete successor to the flip3d D3D11 prototype.

Requirements

• Windows with DWM and DirectComposition
• CMake 3.21+
• Visual Studio / MSVC with the Windows SDK

Build

cmake -S . -B build
cmake --build build --config Release

Run

Launch build/Release/Flip3DComp.exe.

Eligible windows are shown as DWM shared thumbnails on a DirectComposition 3D carousel. No D3D11 scene pass, no Windows.Graphics.Capture.

Controls

• Tab / Shift+Tab, arrow keys, mouse wheel: scroll the carousel
• Enter or left click a card: activate the selected window
• Home: return to the original front window
• Esc: exit
• F5: replay the enter animation

Notes

• vs flip3d: compositor-native visuals (lower overhead), smooth fractional scroll while browsing, uDWM-aligned parallel exit rotation
• More complete: IAccessible + NotifyWinEvent accessibility, Shell Hook live card add/remove
