Bomber+: How to get normalized Depth map layer?

The "Normalized Layer" slave will give you position within the octave blend layers.

How do I get a similar normalized position for the "Depth map" input?

I can get the actual particle depth map value using Center X,Y and a Lookup with the Depth map source - but that is not normalized and it will be very expensive figuring out the min/max values to do the normalization myself (if that is possible at all).

Straight Perlin Noise.. I can't simply use the Noise and "Background" inputs as there is no way to tell what the actual minimum and maximum values are (picked at Center X and Y).

The values sampled from the depth map leads to a different particle order - It is that order I want, or their Z-Index so to speak

Well, I want the index/position/order of the particle when using the depth map input (just like we can get from the octave layer stuff).

I may have been too focused on the normalized depth map wording above

Inside the bomber, the depth map samples are used to determine the particles z-order. However if you try to look up that value your self using the Center X and Y from the same source as the depth map, you don't know what the min and max values are and how they are distributed in between.

You may get one particle depth sample at the value 0.1 and the 800 others between 0.98 and 0.99. This is perfectly valid input that could produce a particle z-order that is virtually the same as if the depth map samples were delivered in a nice evenly spanned sample set between 0 and 1
