Ply

The Ply component loads and displays PLY (Polygon File Format) point cloud files. This is ideal for:

Loading 3D scan data
Displaying pre-processed point clouds
Visualizing LiDAR captures
Loading assets from 3D scanning software

Basic Usage

A minimal example that loads a PLY file from a URL:

python

import os
import numpy as np
from vuer import Vuer, VuerSession
from vuer.schemas import Ply, Scene, OrbitControls

pixelnerf = "pointclouds/pixelnerf.ply"

app = Vuer(static_root=os.getcwd() + "/../../../assets")


@app.spawn(start=True)
async def main(sess: VuerSession):
    # setting the toneMappingExposure to a lower value to make the color look nicer.
    sess.set @ Scene(
        toneMappingExposure=0.4,
        bgChildren=[
            OrbitControls(key="OrbitControls")
        ],
    )

    sess.upsert @ Ply(
        src="http://localhost:8012/workspace/" + pixelnerf,
        size=0.008,
        rotation=[-0.5 * np.pi, 0, -0.5 * np.pi]
    )

    await sess.forever()
