About 2) Pruning hash grid parameters

[GimV88]

Hello,
I would love to know what parameters you pruned in this part: 2) Pruning hash grid parameters with values below 0.1.
Can you help me figure out what this hash parameter represents?

Your assistance in clarifying this matter would be greatly appreciated. Thank you for your time and support.
Best regards

We prune the grid parameters of the neural field for compact color representation, in other words, we prune low-value hash grid parameters (lower than 0.1) of Instant-NGP.
