Depth Map to Surface / Point Cloud
Turn a precomputed depth image into either a relief surface or a perspective point reconstruction with explicit camera assumptions.
Workflow type: Depth-image geometry converter. Status: Functional. Expected result: Export result. Available action: Create depth-derived geometry.
What this 3D tool provides
Convert a precomputed grayscale depth map into an explicit relief surface or perspective point reconstruction online with local processing and camera controls.
- Depth Map to Surface / Point Cloud brings PNG, JPG, WebP, PGM input and the listed STL, GLB, PLY outputs into one review sequence.
- Use the before-and-after labels for orientation, then confirm the selected file with the result guidance and format notes below.
- Accepted input: grayscale PNG, JPG or WebP depth map.
- Available controls: Reconstruction mode, Output, Relief height / depth range, Relief smoothing, Invert near and far, Vertical FOV (degrees), Near depth, Far depth, Perspective depth encoding, Perspective sampling step.
- Review whether you made a relief or a perspective reconstruction, then check the declared depth scale, camera assumptions and output verification before downloading.
How to use Depth Map to Surface / Point Cloud

- Review settings — Review the available controls: Reconstruction mode, Output, Relief height / depth range, Relief smoothing, Invert near and far, Vertical FOV (degrees), Near depth, Far depth, Perspective depth encoding, Perspective sampling step.
- Review and download — Review the measured result and preview before downloading an available export.
Preview and result review
A stone arch depth map combines a strong foreground silhouette with layered recesses to demonstrate surface recovery.
- Before example: A grayscale depth map of a stone arch with near and far regions
- After example: The same depth map reconstructed as an orbitable 3D surface
Depth-derived geometry ready: Review whether you made a relief or a perspective reconstruction, then check the declared depth scale, camera assumptions and output verification before downloading.
Supported inputs and outputs
Input
- PNG
- JPG
- WebP
- PGM
Output
- STL
- GLB
- PLY
Relief mode displaces a regular heightfield. Perspective mode back-projects depth through the chosen field of view, depth encoding and near/far range; it exports GLB or PLY points, not an inferred watertight object.
Available settings
- Reconstruction mode — select; Options: Relief / heightfield, Perspective reconstruction; Default: relief
- Output — select; Options: GLB, Point cloud (PLY), Closed relief (STL); Default: glb
- Relief height / depth range — range; Default: 1; Range: 0.1 to 4; Step: 0.05
- Relief smoothing — range; Default: 1; Range: 0 to 4; Step: 1
- Invert near and far — toggle; Default: Off
- Vertical FOV (degrees) — number; Default: 60; Range: 5 to 175; Step: 1

- Far depth — number; Default: 10; Range: 0.01 to 1000000; Step: 0.1
- Perspective depth encoding — select; Options: Linear depth, Inverse depth, Disparity; Default: linear
- Perspective sampling step — number; Default: 1; Range: 1 to 16; Step: 1

Frequently asked questions
What does Depth Map to Surface / Point Cloud do?
Relief mode turns normalized intensity into height. Perspective mode back-projects normalized depth through your selected FOV, encoding and near/far range.
Which files does Depth Map to Surface / Point Cloud support?
Grayscale PNG, JPG, WebP and PGM depth maps are accepted; relief mode can export a closed STL, GLB or PLY, while perspective mode exports GLB or PLY points.
Is my 3D file uploaded?
Supported file contents stay on this device while the selected tool runs; site analytics and the assistant are separate. The selected file is not uploaded for the supported processing workflow.
What should I review after using Depth Map to Surface / Point Cloud?
The source image must already be a depth map. Perspective output is only as calibrated as its depth encoding and camera settings; it does not infer hidden surfaces or claim watertight geometry.
