Photo to heightmap
Create greyscale depth maps where light and dark values describe carving height.
AI depth map generator
Generate depth maps from photos for CNC carving and 3D relief work
CNC Point Tools converts portraits, artwork, product photos, and reference images into depth maps that can be used for CNC routing, engraving, Aspire, Carveco, Fusion 360, and 3D printing workflows.
Built for real CNC workflows
CNC compatible
Use generated maps in Aspire, Carveco, ArtCAM-style workflows, and CAM software that accepts heightmaps.
Relief ready
Generate bas-relief outputs and continue to STL when you need a 3D mesh.
How to judge a generated depth map
A grayscale depth map is a height description, not a photograph and not a ready-made toolpath. Its tones must be interpreted by downstream CAM software and mapped to a physical height range. Review the grayscale image and the 3D preview together: a bright background, dark background, or inverted subject can change which areas become high or low depending on your CAM import settings.
Start with the image and intended size
Use a sharp source with a distinct subject and crop it to the plaque or part proportions before generation. Small details that are only a few pixels wide may vanish when the map is machined at a small physical size. Leave margin around important features so a frame or finishing pass does not cut them off.
Inspect the depth before cutting
Look for false ridges caused by hard shadows, merged shapes, noisy backgrounds, and abrupt transitions at the border. Import the map into CAM, set the project dimensions and relief height, confirm whether the software needs inversion, then inspect the 3D model and simulate the toolpath. Cutter choice, stepover, material, and machine limits are specific to your setup.
