eat ramen 0 Posted October 20 (edited) Hi guys, I was trying what to map an animated noise which offset in x direction to in circular direction through VEX and attribute Vops. Hopefully can get in offset and follow a spiral. Let's say the x and y are equals to u and v ranging from 0 to 1. The u value represents the angle in polar coordinate and the v value represents the radius. I tried to do that in VEX but results in something below. What's wrong with my code? Here is a code I found written in matlab which might be helpful. This guy exactly what I want to do. https://stackoverflow.com/questions/7580623/how-to-change-an-image-from-cartesian-to-polar-coordinates-in-matlab The reason I want to do that is that I am doing a tornado sim, where the big funnel cloud needs to has some variety on the density. The cloud looks like it has a swimming texture on it, So having this circular/ spiral noise would help a lot and save simulation time! Any alternatives are welcome! Many thanks! circularNoise.02.hipnc Edited October 20 by eat ramen Share this post Link to post Share on other sites
