Hello everyone!
Welcome to another one of my blogs.
So, creating human readable file formats with programs is kinda hard. Commonly its some kind of binary, thats almost impossible to create normally, but here are a few formats that are easy to artificially create!

PPM(portable pixmap format)
This is a very simple image format, with 0 compression, where you just kindof dump the pixels. There is ppm1, ppm3 and ppm6. PPM1 is binary black and white, PPM3 is RGB colors in a text file, and PPM6 is RGB24 colors in a binary form, still very simple to create however!

Only problem with PPM's is their compatibility, cuz only like 2/10 image viewers will actually open this format successfuly.

CSV
CSV is a very simple table format, that is commonly constructed from semicolons, newlines and similiar. Its also really simple to create, because there is no headers to specify anything, just the raw data.

OBJ
Obj is a simple 3d model format, that is plain text, agin with no compression, and is simply constructed from verticies and faces, each verticie having its id, that is later used for specifying the faces. It also supports texture mapping and lighting data, which can also be parse fairly easily!

That will be it for today, see you next time!
