newton.utils.create_sphere_mesh

newton.utils.create_sphere_mesh(radius=1.0, num_latitudes=default_num_segments, num_longitudes=default_num_segments, reverse_winding=False)

Create a sphere mesh with specified parameters.

Generates vertices and triangle indices for a UV sphere using latitude/longitude parametrization. Each vertex contains position, normal, and UV coordinates.

Parameters:

• radius (float) – Sphere radius. Defaults to 1.0.

• num_latitudes (int) – Number of horizontal divisions (latitude lines). Defaults to default_num_segments.

• num_longitudes (int) – Number of vertical divisions (longitude lines). Defaults to default_num_segments.

• reverse_winding (bool) – If True, reverses triangle winding order. Defaults to False.

Returns:

A tuple containing:

• vertices (np.ndarray): Float32 array of shape (N, 8) where each vertex contains [x, y, z, nx, ny, nz, u, v] (position, normal, UV coords).

• indices (np.ndarray): Uint32 array of triangle indices for rendering.

Return type:

tuple[np.ndarray, np.ndarray]
