Hi, I am trying to convert my pts. format file into LFD format on my python. Because I found that .lfd file can be open on notepad and can be read as text file. However, I cannot seem to interpret the structure of the format. The first 3 lines seem quite close to the .pts format, where the first line is the size of the data, and the other 2 lines composed of x, y, z coordinates for first 3 columns, and the other 3 columns for RGB color information. However, this data that I am trying to interpret is definitely longer than 5 as shown on the first line. I am not sure whether my educated guess is even correct. I have asked it to ChatGPT but I am not getting the satisfactory answer. Does anyone know how to interpret the format of .lfd file? It is not so kind as there is no columns labelled and I wonder if anyone is familiar with the format of .lfd.
Here is the piece of .lfd file that I am trying to interpret on Notepad.
