will the sample_sdf_near_surface normalize the mesh to a unit sephere? #33

I read in the code that the sample_sdf will use the points that are sampled from sample_uniform_points_in_unit_sphere, however, I would like to keep the original mesh's vollumetric data (such as height, width..) and the mesh size is various a lot. Do you think I can use a fixed sphere to sample all points? Many thanks!

sorry after a second reading, I have two options, one is to set bounding_radius for all obj files, the other is to set a point array and calculate SDF directly from that point array.
