Isoline
Node-based procedural 3D geometry in the browser. No install
Isoline is a browser-based studio for designing procedural 2D and 3D geometry using a visual node graph. Build shapes from primitives, transforms and smooth boolean operations, then render them as CPU contours, GPU GLSL, or full ray-marched scenes. Isoline uses SDFs and not polygons. Instead of editing vertices, you build geometry by composing mathematical operations. Exports include PNG, ShaderToy-compatible GLSL and binary STL for 3D printing. Free, open source, and no installation required.
Hi Product Hunt! I'm Gaurav, the creator of Isoline.
I built Isoline because I wanted a faster way to experiment with procedural geometry.
Traditional modelling tools are built around polygon meshes. Shader coding is incredibly powerful, but exploring ideas often means writing lots of GLSL before you see any results.
Isoline sits somewhere between those worlds.
You build geometry visually using nodes, while the application generates the GLSL automatically. The same graph can be rendered as CPU contours, GPU-accelerated SDFs, or a fully ray-marched 3D scene. It also exports ShaderToy-compatible GLSL, binary STL for 3D printing, PNG snapshots and scene JSON.
This is intentionally Version 1. The core is stable, but there are still obvious limitations— better positioning, more nodes, materials and workflow improvements are all on the roadmap.
I'd genuinely love to hear what you think. Every piece of feedback helps decide what gets built next.
Thanks for taking a look!
solid launch, congrats! SDF-first instead of mesh feels pretty smart, I believe it skips all the retopo pain that makes smooth booleans fragile on polygons
Finally, a way to sketch SDFs without wrestling with raw GLSL every time. The node graph makes the boolean ops feel intuitive, and exporting straight to STL saved me a trip through Blender.
the node graph makes it really intuitive to iterate on SDF designs, and exporting straight to a ShaderToy-friendly format is a nice touch for quick sharing.
The way Isoline lets you hop from a 2D contour preview straight into a ShaderToy-ready GLSL export without touching a config menu is genuinely elegant, and keeping it browser-only makes the whole thing feel like magic.

Who hunted Isoline ?
Isoline was hunted by Gaurav Tejpal. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
