More explorations of the weird POV effect (which really needs a better name) prompted by comments on earlier videos. This one looks at:
- how different colours affect the effect if the lightness is held constant according to the OKLab colour model,
- how hidden line removal affects the ease of seeing complex 3D shapes,
- how blurring the image affects the effect,
- and whether the effect still works when used in a physical flicker-book/flipbook.
If you're new to this, the 'effect' is that you can't see the cube or any of the other animated shapes if you pause the video - your eye/brain only sees them as a change from one frame to the next, but no individual frame contains a cube or a sphere or whatever.
Contents:
00:00 Colour spaces and OKLab demo
06:25 Test pattern with 35 OKLab colours
11:30 3D shapes with hidden line removal
15:00 Blurred images
15:30 Real life flicker-book/flipbook
16:34 Outro
