Multiple Point Clouds¶

This notebook demonstrates loading multiple point clouds into a single viewer, toggling visibility, and navigating between them.

In [ ]:

# %pip install anymap-ts

# %pip install anymap-ts

In [ ]:

from anymap_ts import PotreeViewer

from anymap_ts import PotreeViewer

Create Viewer¶

Create a viewer with a higher point budget to accommodate multiple point clouds.

In [ ]:

viewer = PotreeViewer(
    height="600px",
    point_budget=3_000_000,
    background="#0f0f23",
    edl_enabled=True,
)
viewer

viewer = PotreeViewer( height="600px", point_budget=3_000_000, background="#0f0f23", edl_enabled=True, ) viewer

Load Multiple Point Clouds¶

Load two different point clouds into the same viewer. Each is given a unique name for later reference.

In [ ]:

viewer.load_point_cloud(
    url="https://potree.github.io/potree/pointclouds/lion_takanawa/cloud.js",
    name="lion",
    point_size=1.0,
    point_size_type="adaptive",
    shape="circle",
)

viewer.load_point_cloud( url="https://potree.github.io/potree/pointclouds/lion_takanawa/cloud.js", name="lion", point_size=1.0, point_size_type="adaptive", shape="circle", )

In [ ]:

viewer.load_point_cloud(
    url="https://potree.github.io/potree/pointclouds/vol_total/cloud.js",
    name="sorvilier",
    point_size=1.0,
    point_size_type="adaptive",
    shape="circle",
)

viewer.load_point_cloud( url="https://potree.github.io/potree/pointclouds/vol_total/cloud.js", name="sorvilier", point_size=1.0, point_size_type="adaptive", shape="circle", )

Toggle Visibility¶

Show or hide individual point clouds by name.

In [ ]:

# Hide the lion point cloud
viewer.set_point_cloud_visibility("lion", False)

# Hide the lion point cloud viewer.set_point_cloud_visibility("lion", False)

In [ ]:

# Show it again
viewer.set_point_cloud_visibility("lion", True)

# Show it again viewer.set_point_cloud_visibility("lion", True)

In [ ]:

# Hide the terrain dataset
viewer.set_point_cloud_visibility("sorvilier", False)

# Hide the terrain dataset viewer.set_point_cloud_visibility("sorvilier", False)

In [ ]:

# Show both
viewer.set_point_cloud_visibility("sorvilier", True)

# Show both viewer.set_point_cloud_visibility("sorvilier", True)

Navigate Between Point Clouds¶

Fly to a specific point cloud to frame it in the viewport.

In [ ]:

# Fly to the lion
viewer.fly_to_point_cloud("lion")

# Fly to the lion viewer.fly_to_point_cloud("lion")

In [ ]:

# Fly to the terrain
viewer.fly_to_point_cloud("sorvilier")

# Fly to the terrain viewer.fly_to_point_cloud("sorvilier")

In [ ]:

# Fit all point clouds in view
viewer.fly_to_point_cloud()

# Fit all point clouds in view viewer.fly_to_point_cloud()

Remove a Point Cloud¶

Remove a point cloud from the viewer entirely.

In [ ]:

viewer.remove_point_cloud("sorvilier")

viewer.remove_point_cloud("sorvilier")

In [ ]:

# Check remaining point clouds
viewer.point_clouds

# Check remaining point clouds viewer.point_clouds

Adjust Global Settings¶

Settings like point size and point budget apply to all loaded point clouds.

In [ ]:

viewer.set_point_size(2.0)
viewer.set_background("#1a1a2e")

viewer.set_point_size(2.0) viewer.set_background("#1a1a2e")

In [ ]:

viewer.reset_camera()

viewer.reset_camera()
