fstl is a viewer for .stl files. It uses Qt.
It is optimized to quickly load and render very high-polygon models.
The Porsche model below is two million triangles. On a mid-range laptop, this model loads in one second and renders at a smooth 60+ frames per second.
For comparison, Meshlab takes several seconds to load and renders at about 15 frames per second. More sophisticated software has an even larger overhead — Blender took about 12 seconds and locked up while loading.
This is free and open source software.
Features include:
- Fast.
- Attractive.
- Models are rendered with per-face flat shading and anti-aliasing in a smooth color scheme reminiscent of Solarized.
- Cross-platform support – runs under Linux, macOS, and Windows.
