You can see the colorizing effect of the birefringent stressed plastic on the lid of a Pringle’s can when illuminated by an LCD monitor’s polarized light, but not in normal lighting.
@ID_AA_Carmack Or is it slightly concave, acting as a magnifying glass, and what you're actually seeing is a close-up of just a few RGB pels?
@ID_AA_Carmack Polarization can be fun to play with.
@ID_AA_Carmack It’s funny when you notice real world details that someone would suspect were a bug if they were produced by a rendering pipeline Are there are examples of such real world visual phenomenon that were discovered in simulation and then verified in real life?
@ID_AA_Carmack More then meets the eye. Birefringence is a property of transmission not reflection, it’s the second surfaces internal reflection, interacting with the first surface. In a thicker example the color only extends out to the second surface interaction. Like an oil film on water.
@ID_AA_Carmack john its 11 at night on a tuesday why you peepin on these pringles lids so intensely
@ID_AA_Carmack The real scientific question is ‘how many Pringles can you eat in a oner?”.
