max attribute value

[PhasmaCeritus]

Hi,

I have a quick question how can I create a custom point attribute that would have a max attribute value.

For example we have three points how could I get a custom attribute with highest Y values.

P[x]_P[y]_P[z]___CustAtt

0____1____0______5

0____3____0______5

0____5____0______5

I am creating a tool that would give me normalized point distances from a certain point. And I got stuck on normalizing values for which I need to divide calculated distances by the distance of the furthest point.

Please tell me if you know a better way how that could be done...

PS if somebody knows simpler way to measure distances between two points than using point expression and punting it in to uber long expression line - please share

Thanks

Check this Houdini Help page.

Just using a vopsop to get the distance and some sorting to get min and max distance to normalise with. min and max are detail attributes. ..

normDistToPoint.hipnc

hehehe . i was just in need for function like this.

But since i can not afford reordering points i made python sop..

the result is the same without reordering.

I didn't figure out how varmap detail attribute works in python, the attribute is not mapped.

So later on you need to access attribute with point expression, something like that:

point("../NormDistance1", $PT, "normDistance",0)

NorDistance.otl

excellent, that's really helpful

thanks a lot
