3D Video Without Glasses From Any Viewing Angle - '3D-Unframed'™ or 3DU™

Decreasing contrast for the focal point of the camera's video recoding to the outermost frame produces the principal 3 dimensional relief. The central-most frame must display the greatest possible image illumination, while the rest of the frame is progressively lower in illumination.

To measure the effectiveness of the 3 dimensional effect calculate the ratio between the centre-middle frame to the outermost diagonal luminosity, as the standard calibration. See Xerqon blog Natural Distribution article, https://www.centreweave.com/post/normal-distribution-function-simplified for the technical solution to the contrast by luminosity gradient variation. Simply substitute the amplification of "1", in the article example, to a constant, "( a/2 )".

When correctly followed, this technique will deliver 3 dimensional imagery without any requirement for 3 dimensional image filtering glasses. The imagery will increase in dimensional effect for light or for sound when surround sound is similarly fidelity adjust from high to low - as taken from centre-middle to the outermost audio device (speaker). Cinema and home theatre would benefit from this powerful evolutionary leap forward as a technological disruptor. It represents market repositioning all to accpetance of the swiftly emergent, industry profit centre.

Contrast as a 3 dimesional gradient was first published as a technology in 2025.
