` block with an updated version that includes the options for ln, sin, and sgn.\n\nFor main.js, I need to update the top constants and the applyBtn handler to read the function. I'll ensure that the applyLogWarp can accept a mode parameter and modify its signature to include the new fn parameter, so it computes the mapping per axis and function.\n**Crafting replacements for main.js**\n\nI’m going to search for `const axisSel = document.getElementById('axis');` in main.js. Then, I'll add a new line to create `const fnSel = document.getElementById('fn');` so I can access the selected function. \n\nAfter that, I'll update the applyBtn handler to include `fnSel.value`. I need to modify the relevant function accordingly—ensuring all replacements are precise. \n\nNow, I’ll create search and replace blocks to reflect these changes effectively.\n\nI will add a function selector (ln, sin, sgn) to the UI and update the JavaScript to apply the chosen positional warp mode.\n\nindex.html\n```index.html\n```\n\nmain.js\n```main.js\n```\n\nmain.js\n```main.js\n```\n\nmain.js\n```main.js\n```\n\nSummary: I added a \"Function\" selector to the UI and updated the JS to accept three warp modes — ln (existing log warp), sin (a smooth sinusoidal positional warp influenced by strength), and sgn (a hard step/threshold warp using strength to set the threshold) — wiring the chosen mode into the pixel remapping loop.","page_description","This page allows users to upload an image and apply various mathematical warp effects to it using functions such as logarithm (ln), sine (sin), and sign…","cursor","eyJpZCI6IjlzNWNhbjY3bjlsaDF0dnlheXlxIn0","token","included",[],"about",{"_182":-5},"parent","routes/browser/layout","actionData","errors"]
