New projection method

• Replaced two pass rendering with a single pass.
• Changed 3D rotation with ray intersection and planar homography to make the transform look better.
• Cheaper blur effect.

Framerate improvements

Now runs at high refresh rate! Feels way more responsive!

Performance improvements

Reduced resource usage in background:

• Now pauses capture when effect is inactive
• Stops rendering entirely when inactive

This drops the CPU and GPU usage to 0 if it's not triggered by the accelerometer values.

Bug fixes and quality improvements

Improved quality and this time a standalone exe!

• Now uses DWM alpha rather than hide attribute to reduce flicker on visibility state change.
• No longer steals focus
• Fixed calibration at launch (no longer calibrates by smoothed value)
• More deadzone margin at calibration
• Removed shader file dependency
• Slightly smaller binary

Demo release

The shader files are required to be in the same folder as the executable for it to launch, but I might do a release later where they aren't necessary they're just the default shaders of my DX graphics library which I used to build this.

Press space to calibrate if the angle calulcation is wrong at startup.
