Mathematically speaking, what does the transparency control do?

[FrankEscobar]

Is it a sum over the transparency value of each splat? is it a multiplier of the type 1+transparency? is it a pow control?

Thank you in advance!

Hello,

At render time the gaussian's opacity is updated as follows:

opacity *= e ^ sliderValue;

Where sliderValue has range [-6..6].

Thanks!
