Polygon Shape using Affinity Photo's Procedural Texture Filter

In this video, I show how to make a polygon shape using Affinity Photo's procedural texture filter. Polygon: var s=360/n; var v=vec2(rx,ry)*a/w; var th=atan2(v.y,v.x)+ph; var tp=th-s*floor(th/s+.5); osc(length(v)*cos(tp)) I originally saw this formula in "The Book of Shaders." https://thebookofshaders.com/07/ Shader Polygon using Affinity Photo's Procedural Texture Filter https://youtu.be/apZnZsDdXTs?si=fB6m0_YOSt8z7LAY Procedural Textures Playlist: https://www.youtube.com/playlist?list=PLPTJk1HIMN35WOCDXnoUB-l2_YVgJ8rHK The Procedural Texture filter and related information can be found on Affinity Photo's website: https://affinity.help/photo2/en-US.lproj/pages/Filters/filter_proceduraltexture.html 0:00 Introduction 1:10 Making a vertical line in polar coordinates 2:16 Using the floor function to transform the angle 5:26 Implementing the polygon filter 10:15 Conclusion
