From image to borehole

  1. Choose your image. Use one of the four samples, or drop a PNG, JPEG or WebP. Images must already have depth running vertically.
  2. Map the depth. Enter image top and bottom. These are arbitrary pseudo-depth coordinates, not a calibrated measured depth.
  3. Select an interval. Drag down the track, use the handles on its right, or enter slice top and bottom. Drag the middle of the selection rail to move the interval.
  4. Set the diameter. Diameter and depth use the same pseudo units. Cylinder length always equals slice bottom minus slice top. No vertical exaggeration is applied.
  5. Explore the cylinder. Drag freely in any direction to turn the cylinder in 3D, including past its ends and upside down. Drag near the edge for a rolling motion, or use Shift + drag / Roll mode for pure roll. Scroll to zoom. Arrow keys rotate; Q/E roll; Home resets. The sliders and Side view / Top view buttons provide exact orientations. Cyan shows its front-facing half on the track. The dashed line marks the exact central azimuth. A band crossing 0° splits across both image edges. Looking exactly along the cylinder axis hides the side-wall highlight because only a cap faces you.

Image left is 0°, image right is 360°. These are image-relative directions, not geographic north. The seam is at the left/right image join. Top and bottom caps are neutral; image texture covers the side wall only.

Save project includes the source image and settings in a local JSON file. Export view PNG captures both linked plots. Uploads remain local. Very large images are reduced for the GPU texture; the original remains in the project.

Samples 1–3 are visual demonstration assets created during image editing; they are not calibrated measurement data. Sample4 is the supplied image without rotation.
