A very unusual optical illusion is making internet users question their sight - after a simple animated image of a rotating grid made parts of the picture 'disappear'disappear
We have tested the method by integrating the wave equation on a rotating grid, where it remains stable even when the grid speed at the edge is 15 times the wave speed.
ComboScreen was modified to include the following features: image rotation, adjustment of image brightness and contrast, ability to rotate the grid, ability to copy a sized grid from one panel to another, sorting of the hybridization bottles list, recall of scoring information (grid information saved as.gda file), and the ability to score the intensity of the hybridization signal.
In this case, the solution becomes grid independent: Changing the mesh (i.e., shifting or rotating the grid) does not affect the solution.
Goto shines a projector onto to the rotating wire grid and a walking person appears.
Then rotate the grid to align with the horizon.
In baseline blocks the grid remained stationary for a twenty-second epoch, followed by an epoch where the grid rotated clockwise around its center at a speed of 270 degrees per second.
The dorsal and medial edges of the grid were manually annotated and used to flip or further rotate all grids into a common reference frame.
Unlike the first bulge grouping, which occurred as a result of fine-scale DoG filtering, the DoG output of the pattern at coarse scales results in edge movements of the 'central tile' with the tilt effect appearing in a different direction (nearly 45° rotated from the grid) due to the 'X-shape grouping' structure, which groups the background checkerboard tiles together.
In each stimulation block, a cyan (CIE x = 0.222, y = 0.331) dot was presented in one of the four quadrants (left top, left bottom, right top, and right bottom) on a black (CIE x = 0.275, y = 0.437) background on which cyan (CIE x = 0.204, y = 0.272) cross elements arranged in a grid rotated counterclockwise around the center point at a constant speed (70°/sec) (Figure 1).
