Hi, You cannot invent new data between point without doing an interpolation. Your choice of interpolation will determine the quality of this data. The only way I can think of is to create a raster from this TIN. Then, resample (re-interpolated) this raster with a finer pixel and then make a new TIN. This may create a finer TIN but this will significantly alter the original data. You would need to evaluate the results and keep a backup of the old files.
Alternative, I would try with Mesh Lab. It’s open source and probably has Mesh densification methods that would be more adapted. Cloud Compare also has interesting algorithms.
