# STL Texturizer
|
|
|
|
**Live demo:** https://cnckitchen.github.io/stlTexturizer/
|
|
|
|
A browser-based tool for applying surface displacement textures to STL files — no installation required.
|
|
|
|
Load any `.stl` file, pick a texture, tune the parameters, and export a new displaced STL ready for slicing.
|
|
|
|
## Features
|
|
|
|
- **Texture presets** — 17 built-in seamless textures (basket, brick, bubble, carbon fiber, crystal, grip surface, hexagons, knitting, knurling, leather, noise, voronoi, weave variations, wood, and more)
|
|
- **Custom textures** — upload your own image as a displacement map
|
|
- **Projection modes** — Triplanar, Cubic (Box), Cylindrical, Spherical, Planar XY/XZ/YZ
|
|
- **UV transform** — independent U/V scale, offset, and rotation controls
|
|
- **Displacement amplitude** — fine-tune depth from subtle grain to deep relief
|
|
- **Surface mask** — skip horizontal top/bottom faces to keep flat surfaces clean
|
|
- **Surface exclusions / inclusions** — paint individual faces with a brush or bucket-fill to exclude or exclusively include them from displacement
|
|
- **Live preview** — real-time textured 3D preview with orbit/pan/zoom controls
|
|
- **Mesh subdivision** — auto-subdivides coarse geometry before displacement for smoother results
|
|
- **Export** — downloads a new binary STL with displacement baked in
|
|
- **Light / Dark theme** — persisted per browser
|
|
- **Multilingual** — English and German UI
|
|
|
|
## Usage
|
|
|
|
1. Open `index.html` in a modern browser (Chrome, Edge, Firefox, Safari).
|
|
2. Drop an STL file onto the viewport or click **Load STL…**.
|
|
3. Select a texture preset from the sidebar (or upload a custom image).
|
|
4. Adjust projection mode, UV scale, offset, rotation, and amplitude.
|
|
5. Optionally mask or exclude surfaces with the brush/fill tools.
|
|
6. Click **Export STL** to download the displaced mesh.
|
|
|
|
> **Note:** All processing runs entirely in the browser — no data is uploaded to any server.
