Question about implementation of logistic density distribution in volume rendering method

[a-ibrahimi]

Hi,

I've been exploring your GitHub repository and noticed a mention of a logistic density distribution in the paper. However, I couldn't locate the corresponding implementation in the code.

The paper states

I'm curious to know how this logistic density distribution is utilized within the volume rendering process.

Could you please provide some guidance on where I can find the implementation of the logistic density distribution in your code?

Thanks in advance!
