3d point cloud and normal vector to the surface

I am using 3d laser scanner , and have x,y and z axis from my sensor these three points which are of 120x160 each, now what i want to know is that how can i build 3d point cloud from my these three points and how can i draw the normal to the surface in the resulting point cloud.

Answer 1

As of now, pcshow is available for displaying point clouds and quiver3 is effective to show the normal vectors.

Please find here for the detail.

scatter3 would be useful for drawing the point cloud.

surfnorm and/or quiver3 would be useful for displaying the normals.

but scatter3 works for vector and i have 120x160 set of values for x,y and z

Convert your x, y, and z arrays into vectors with the colon operator:

scatter3(x(:), y(:), z(:))
