uvisbox.Modules.ConeGlyphs.cone_glyphs_mesh.cone_glyphs_mesh(positions, stats_3d, point_values=None, scale=0.5, resolution=10)[source]

Build 3D cone glyph mesh from statistics.

Parameters:

  • positions (numpy.ndarray) – Shape (n, 3) - glyph positions

  • stats_3d (dict) – From cone_glyphs_summary_statistics()

  • point_values (numpy.ndarray, optional) – Shape (n,) - scalar values for coloring

  • scale (float) – Glyph scale factor (default: 0.5)

  • resolution (int) – Circle resolution (default: 10)

Returns:

mesh_3d – Contains points with shape (k, 3), polygons with shape (m, 3), and point_values with shape (k,).

Return type:

dict

uvisbox.Modules.ConeGlyphs.cone_glyphs_mesh.cone_glyphs_meshing(positions, min_vectors, median_vectors, max_vectors, scaler_values, glyph_markers, scale, resolution, num_of_glyphs)[source]

Build superelliptical squid glyphs for 3D visualization. Assumes vectors are in spherical coordinates (magnitude, theta, phi).

Parameters:

  • positions (numpy.ndarray) – Array of shape (n, 3) The positions of the squid glyphs.

  • min_vectors (numpy.ndarray) – Array of shape (n, 3) The minimum vectors in spherical coordinates.

  • median_vectors (numpy.ndarray) – Array of shape (n, 3) The median vectors in spherical coordinates.

  • max_vectors (numpy.ndarray) – Array of shape (n, 3) The maximum vectors in spherical coordinates.

  • scaler_values (numpy.ndarray) – Array of shape (n,) The scaler values for each glyph.

  • glyph_markers (numpy.ndarray) – Array of shape (n,) with values 0 (no glyph), 1 (full glyph), 2 (arrow only)

  • scale (float) – The scale factor for the glyphs.

  • resolution (int) – The resolution of the base circle of the squid glyph.

  • num_of_glyphs (int) – The number of glyphs to be created.

Returns:

  • points (numpy.ndarray) – Array of shape (m, 3) The points of the squid glyphs.

  • polygons (numpy.ndarray) – Array of shape (k,) The polygon connectivity for the glyphs.
