Sample Datasets¶

This notebook demonstrates loading different publicly available Potree point cloud datasets. Each dataset has different characteristics — from small object scans to large-scale terrain surveys.

Lion Takanawa¶

A 3D scan of a lion statue at Takanawa, Japan. This is a small, detailed object scan with RGB color data.

In [ ]:

viewer = PotreeViewer(height="600px", point_budget=1_000_000, background="#1a1a2e")
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

viewer = PotreeViewer(height="600px", point_budget=1_000_000, background="#1a1a2e") 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

Sorvilier (Vol Total)¶

A large-scale aerial LiDAR survey of Sorvilier, Switzerland. This dataset covers terrain, buildings, and vegetation over a wide area. Courtesy of sigeom.sa.

In [ ]:

viewer2 = PotreeViewer(
    height="600px",
    point_budget=2_000_000,
    background="#0a0a1a",
    edl_enabled=True,
)
viewer2.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",
)
viewer2

viewer2 = PotreeViewer( height="600px", point_budget=2_000_000, background="#0a0a1a", edl_enabled=True, ) viewer2.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", ) viewer2

Comparing Point Shapes¶

Load the same dataset with different point shapes to see the visual difference. Paraboloid shape adds a 3D shading effect that enhances depth perception.

In [ ]:

viewer3 = PotreeViewer(
    height="600px",
    point_budget=2_000_000,
    background="#000000",
    edl_enabled=True,
)
viewer3.load_point_cloud(
    url="https://potree.github.io/potree/pointclouds/vol_total/cloud.js",
    name="sorvilier_paraboloid",
    point_size=2.0,
    point_size_type="fixed",
    shape="paraboloid",
)
viewer3

viewer3 = PotreeViewer( height="600px", point_budget=2_000_000, background="#000000", edl_enabled=True, ) viewer3.load_point_cloud( url="https://potree.github.io/potree/pointclouds/vol_total/cloud.js", name="sorvilier_paraboloid", point_size=2.0, point_size_type="fixed", shape="paraboloid", ) viewer3

Adjusting EDL for Terrain Data¶

Eye Dome Lighting (EDL) is especially useful for terrain data where depth cues help distinguish elevation changes.

In [ ]:

# Strong EDL for terrain visualization
viewer2.set_edl(enabled=True, radius=2.0, strength=0.8)

# Strong EDL for terrain visualization viewer2.set_edl(enabled=True, radius=2.0, strength=0.8)

In [ ]:

# Disable EDL to see the difference
viewer2.set_edl(enabled=False)

# Disable EDL to see the difference viewer2.set_edl(enabled=False)

In [ ]:

# Re-enable with default settings
viewer2.set_edl(enabled=True, radius=1.4, strength=0.4)

# Re-enable with default settings viewer2.set_edl(enabled=True, radius=1.4, strength=0.4)

High Point Budget¶

Increase the point budget to see more detail in the terrain dataset. Higher budgets require more GPU memory.

In [ ]:

viewer2.set_point_budget(5_000_000)

viewer2.set_point_budget(5_000_000)
