mne.decimate_surface(points, triangles, n_triangles)[source]¶

Decimate surface data.

Note. Requires TVTK to be installed for this to function.

Note. If an if an odd target number was requested, the quadric decimation algorithm used results in the next even number of triangles. For example a reduction request to 30001 triangles will result in 30000 triangles.

Parameters:	points : ndarray The surface to be decimated, a 3 x number of points array. triangles : ndarray The surface to be decimated, a 3 x number of triangles array. n_triangles : int The desired number of triangles.
Returns:	points : ndarray The decimated points. triangles : ndarray The decimated triangles.
