HOLD and DRAG the Screen to Rotate Press SPACE to Save as OBJ and MTL Better On Turbowarp: https://turbowarp.org/1264059426 If you have lag, move the Marching_Cubes_Intervals slider to the left Try The Original Untextured Marching Cubes Project: https://scratch.mit.edu/projects/1255604870 To review Built-In Functions, change the Function Example slider To change mesh detail, change the MARCHING_CUBE_INTERVALS slider ( don't go over ~50 without Turbowarp ) If you want to generate a mesh for a different function, go inside and change the output of "Marching Cubes Function" Credits: Inspired by https://scratch.mit.edu/projects/1017250219/, but no code is taken gist.github.com/dwilliamson/c041e3454a713e58baf6e4f8e5fffecd for Marching Cubes LUT https://scratch.mit.edu/projects/971821375/ for Trifill 3D Perlin Noise For Mesh Generation OBJ and MTL download is done with a data URI "Plato was right. Earth is made, on average, of cubes" Update 1/15/2026: Rehauled rotation engine to use intrinsic rotation matrix, transformed quick sort into BSP for massively increased FPS, replaced alll recursion with loops to prevent "too much recursion" compiled Turbowarp error, and removed Herobrine Update 1/30/2026: fixed normal-center terrain programming bug and removed Herobrine
