Zivid.PointCloud.transform(numpy.array([4,4], dtype=numpy.float32))

[MysteryNull]

Could you please tell me about the source code of the function "Zivid.PointCloud.transform(numpy.array([4,4], dtype=numpy.float32))"?
Thank you!

Hi!

It transforms the PointCloud by matrix-multiplying the 4x4 matrix by each point represented as a 4-vector [x0,y0,z0,1] which yields new points [x1,y1,z1,1]. The transformation matrix should be an affine transform representing only Rotation+Translation.
