thecatpetter Posted February 26, 2019 Posted February 26, 2019 Hello! Would it be possible to add a Glass distortion effect? This would be extremely beneficial. I'm trying to make a photo with a heat warp effect and all the tutorials I can find are using PS' Glass distortion effect... Thanks. saint77 1 Quote

If any of "my" posts are wrong or appear to be total b*ll*cks they are the ones generated by the AI. If correct they were probably mine. I apologise for any mistakes made by my AI - I'm sure it will improve with time.

John Rostron Posted March 20, 2019 Posted March 20, 2019 My usual response for effects like this is to reach for the Equations filter. I had a quick experiment adding a sine wave to both the x and y axes. The problem is that you need several parameters and the Equations filter only offers three. Anyway, here is a first try. Go to the Equations filter, Filters > Distort > Equations. In the x= and y= sections enter: x=x+5*c*sin(360*y/h)+5*b*cos(270*y/h) y=y+5*a*sin(360*x/w)+5*b*cos(270*x/w) The a, b and c are parameters that affect the amplitude of the fuzziness. You can use the a, b and c sliders to modify these. The 5 is a hard-wired additional scaling factor for the amplitude. The 360 and 270 are hard-wired factors which affect the wavelength of the fuzziness. Here are a pair of images. The first is the original, the second has the fuzziness applied. Is this on the right lines for creating the desired heat haze or hammered glass effect? I can continue with this and create a macro if you think it useful.
