Let me explain better my problem: I have n (many millions) laser points data in a numpy array: laser_points.shape = (1000, 3) the columns are the x, y, z coordinates of these points in 3D space. These points are irregularly spaced and are the result of a survey on a real world object

Hello Andreas, I have (many) millions of point coordinated (X, y, z) in 3D space (easting, westing, height) like these: import numpy as np x = np.random.random(1) y = np.random.random(1) z = x * np.exp(-x**2-y**2) So the points are: p = (x, y, z) I need to interpolate them to a

Hello, I wonder if it is possible to use PyCUDA to grid on a two dimensional regular grid xyz scattered data. Our datasets are usually quite large (some millions of points) . Many thanks for any help in this topic. Roberto Vidmar --
