Image To Relief Stl

**Judgement:** A strong, focused tool for turning flat-color or grayscale images into watertight bas-relief STL models, particularly effective when used after image-generation skills that can produce clean, segmentable masks. High utility for automated pipelines and 3D-print workflows, but requires suitable input images and some parameter tuning. **Strengths:** - Purpose-built for orchestrator use: deterministic CLI with clear parameters and no heavy CAD stack. - Supports both palette and grayscale modes, giving precise control over the height of each region. - Produces watertight, print-ready ASCII STL and an optional SVG preview to inspect relief geometry. - Exposes practical knobs (base thickness, pixel size, height range) to balance detail vs. file size. **Key Risks / Limitations:** - Relies on “clean” input images: flat colors, no gradients, no antialiasing, and clear edges. Standard photos or shaded artwork will yield poor segmentation or noisy meshes unless preprocessed. - Large images or very small `--pixel` values can produce very large STLs and increase memory/CPU usage. - Does not perform advanced CAD-style operations (e.g., smoothing, fillets, supports); users must handle such post-processing elsewhere. **Recommended Scenarios:** - As a downstream step after an image-gen skill (e.g., nano-banana-pro) configured to output N solid colors with sharp boundaries, to create bas-relief prints. - For logos, emblems, plaques, and stylized art where the designer can constrain the palette and avoid gradients. - In automated or programmatic 3D-print pipelines where reproducibility and lack of heavy dependencies are important, and where image preparation can be standardized upstream.
