WebBy default, gl_FragCoord assumes a lower-left origin for window coordinates and assumes pixel centers are located at half-pixel centers. For example, the (x, y) location (0.5, 0.5) is returned for the lower-left-most pixel in a window. The origin of gl_FragCoord may be changed by redeclaring gl_FragCoord with the origin_upper_left identifier. WebSo if you have some vert positions around the origin (-0.5, 0.5) then they would rotate about their centre which is also the screen centre but if you offset them (1.5, 2.5) they would rotate about the screen centre which is no longer their centre. I think what you want is to do is add a translation to your model matrix (and remember matrix ... bitfiery app https://windhamspecialties.com
