Hello everyone.

I have this Houdini scene that reads a motion vector sequence and compare 2 frames to read the lowest pixel value (in my example: lowest red). It work for the 2 frame, but I would like to do it for the entire sequence. I didn't find a way to keep the lowest value throughout the sequence.



At frame 63, the lowest value is at this frame (now: -1.0913). This is good.



At frame 64, the lowest value is at the previous frame (prev: -1.0913). Still good, it is the lowest value so far.



At frame 65, both value are higher than the lowest value we got so far and the result is the lowest value between the two frames (prev: -1.04709). This is now what I want. I would like RESULT to keep the lowest value so far (-1.0913).



But I have not find a way to do that. If someone have a solution to this, it would help me to automize the sequence analyze.

Thankyou.
Pierre Lalancette.

After merging what I know of the two scenes, I was able to boil my water. Yeah!

Unfortunately now, I am unable to render it. The fluid wants something that I don't know or understand. I tried to give it what it wants, but all I could get was the surface preview.



Does anyone have an idea why?

After revision, the way Chris does it, it is not possible to get a tank other than square.
I'm trying to do it into a sphere.

Still don`t know how to achieve this.
Pierre.
