    Open3D is a modern open-source library for 3D data processing with support for point clouds, meshes, RGB-D images, and more. It provides both Python and C++ APIs, enabling rapid prototyping and high-performance applications.

    Below is a simple Python example that demonstrates creating a 3D geometry, computing normals, and visualizing it.

    import open3d as o3d
    import numpy as np

    # Create a sphere mesh
    mesh = o3d.geometry.TriangleMesh.create_sphere(radius=1.0)
    mesh.compute_vertex_normals()

    # Apply a rotation transformation
    R = mesh.get_rotation_matrix_from_xyz((np.pi / 4, np.pi / 4, 0))
    mesh.rotate(R, center=mesh.get_center())

    # Visualize the mesh
    o3d.visualization.draw(mesh, raw_mode=True)
    Copied!

    How it works:

    • create_sphere() generates a sphere mesh.

    • compute_vertex_normals() calculates normals for smooth shading.

    • get_rotation_matrix_from_xyz() creates a rotation matrix from Euler angles.

    • rotate() applies the transformation to the mesh.

    • draw() opens an interactive 3D viewer.

    For a slightly more advanced example, here’s how to visualize two intersecting boxes:
