The Laser Read
Computed method · synthetic input
How much can you reconstruct from a few angles?
Try a few pings, then Sweep. Turn on the truth overlay and compare the emerging shape with the synthetic object.

About this tool
What you are looking at
The tool takes parallel line-integral projections of a hidden synthetic density, then uses back-projection to reconstruct it. Fidelity is the Pearson correlation between the running reconstruction and the known synthetic truth. The tomography mathematics is computed, but the input is synthetic rather than physical laser or scanner data.
How to use it
Drag to choose an angle and select Ping, or use Sweep to collect multiple angles. Compare filtered and unfiltered back-projection, optionally reveal the known truth, adjust object complexity, or Reset. Read the ping count and fidelity. Sparse angles produce streaks; broader angular coverage improves the result within the limits of the grid, bin, and filter resolution. The reconstruction remains imperfect.
