question about freq mask code

[Selena]

Looking at the frequency mask computation function, I'm a bit confused on this line. Wouldn't this always constraint ptr to be <2 ? How would we be able to mask more frequencies this way?

FreeNeRF/internal/math.py

Line 300 in 2dc3f6d

 ptr = pos_enc_length / 3 * current_iter / total_reg_iter + 1

Pos_enc_length = (L*2+1)*3. So ptr would not always be less than 2.
Maybe you can print the length of the position encoding feature.:)
