# Point Cloud Viewer

![Gopher](images/gopher-small.png)
A simple point cloud viewer built with [Fyne](https://fyne.io/). This repository primarily offers a Fyne widget for viewing point clouds, but it also contains a standalone viewer. The standalone viewer

Reads PLY, PCD, PTS, and XYZ files and renders them as interactive 3D point clouds with mouse-controlled rotation and zoom.

# seabed

Procedurally generated seabed terrain with bathymetric depth coloring.

go run .

Layered noise produces hills, a trench, scattered rocks, and sand ripples.
Color goes from dark blue in the deep parts to sandy tan at the peaks.
Every regeneration uses a new random seed so you get a different landscape
each time.

## controls

- Height -- adjusts terrain relief without regenerating. Crank it down
for a nearly flat ocean floor or up for exaggerated peaks.
- Points -- log-scale slider from 100K to 50M. Set the value and hit
Regenerate to rebuild at the new resolution.
- Regenerate -- new random terrain at the current point count.
