DEPTHMAP / RELIEF ENGRAVING, PROCESS SIGNAL FLOW

01Choose SourceLoad and inspect the original image in the browser.

02Initialize DepthmapRun the depth model to create the grayscale base.

03Guide with ColorOptionally apply a Depth Palette and choose active swatches.

04Adjust + PaintSet range, curve, size, border, and manual depth corrections.

05Review + ExportCompare previews, then download an 8-bit, 16-bit, or Krasnow-style parallax PNG.

Iterate color guidance, adjustments, and painted corrections until the grayscale depth and relief projection describe the intended form.

Perimeter padding depth Lowest point

Width and height are linked artwork dimensions. Editing either dimension automatically recalculates the other. Border padding initially extends the image's lowest existing height around all four sides. Moving Perimeter Padding Depth overrides that automatic value.

Click or drag directly on the grayscale depth preview to replace an area with the selected relative depth.

An 8-bit image contains 256 gray levels. The 16-bit export contains 65,536 levels and preserves smoother gradients for compatible downstream software.

Color-Guided Depthmap

Choose a saved Depth Palette, then toggle the swatches that should influence this image. Artificial depths and influence values are configured only in Swatch Palette Vault.

Color-guided depth is optional. Sign up or sign in to access Swatch Palette Vault, where you can create a Depth Palette that maps colors to artificial depth and perspective influence.

Parallax

Convert the current depthmap into Krasnow-style horizontal angle ramps, inspect exactly what will remain unengraved, and export raster or grating geometry.

The parallax export applies Ben Krasnow's horizontal depth-edge conversion in this browser. The cutoff marks the farthest portion of an AI-generated map as unengraved background; strength controls the length of the angle ramps at its boundaries. Existing depthmaps use their explicit pure-white or transparent background instead.

The Parallax PNG is an 8-bit angle map. The Parallax SVG converts that map into black, square-cell grating geometry but does not embed laser settings.
