The very Mysteric Detail Threshold

Post by FlorianK » Tue Oct 04, 2011 4:08 pm

In the manual, it (briefly) says Detail Threshold (DT) was a value to detremine how fine or coarse the "find underresolved area in fluid" algorithm works. As this gives me a slight idea of the meaning of DT, I still have problems understanding how to use this very important parameter in the correct manner.

For example when adding Splashes, setting DT to 0 means there aren't any splashes created at all. Using different values very often results in what I call Snowballs, Splash particles popping in on areas not even close to the actual grid fluid in the form of a snowball. I watched this behavior mostly when animated geometry was involved.
I found the best results were created when deactivating Use Detail Threshold, but how is the engine determining where to place particles, then? Also, If I use different values for DT (i.e. not use it on Splash, have it set to 0.5 for foam), how are those elements supposed to be fitting together in the end?

Finally, when do you recommend higher values for DT and when not? What is the copncept behind it?
