render-stl-png

Render an STL to a PNG from a nice, consistent 3D angle ("Blender-ish" default perspective) with a solid color.

This is a deterministic software renderer:

No OpenGL
No Blender dependency
Uses a simple camera + z-buffer + Lambert shading

Inputs

STL file path (ASCII or binary)
Output PNG path

Parameters

```
--size <px>
```
: image width/height (square), default
```
1024
```
```
--bg "#rrggbb"
```
: background color, default
```
#0b0f14
```
```
--color "#rrggbb"
```
: mesh base color, default
```
#4cc9f0
```
```
--azim-deg <deg>
```
: camera azimuth around Z, default
```
-35
```
```
--elev-deg <deg>
```
: camera elevation, default
```
25
```
```
--fov-deg <deg>
```
: perspective field of view, default
```
35
```
```
--margin <0..0.4>
```
: framing margin as fraction of view, default
```
0.08
```
```
--light-dir "x,y,z"
```
: directional light vector, default
```
-0.4,-0.3,1.0
```

Usage

One-shot

python3 scripts/render_stl_png.py \
  --stl /path/to/model.stl \
  --out /tmp/model.png \
  --color "#ffb703" \
  --bg "#0b0f14" \
  --size 1200

Wrapper (recommended)

The wrapper creates a cached venv (so

pillow

is available) and runs the renderer.

bash scripts/render_stl_png.sh /path/to/model.stl /tmp/model.png --color "#ffb703"

Notes

This is meant for marketing/preview images, not photorealism.
If you need studio lighting / materials, use Blender — but this gets you 80% quickly and reproducibly.
