So..... If there is anyone out there who can share any insight to strand mechanics in ICE I'd really enjoy hearing your thoughts.
I took the OEM "Create Strand from Curves" Task and modified it into something where I can animate the strand along the curve, generate dashed lines, strand masking, transparency, offset, length, direction, etc, etc. I've run into a couple things which puzzle me. 1. The default strand draws with a round tip on one end and a flat tip on the other. Can't really quite figure out why the particle segment is being cut in this way. Any ideas? 2. When I reposition the strand along the curve, that is to push the strand back towards the start of the curve at least partially, I sometimes get artifacts in the strand trail where the end of the strand is terminated at the end of the curve. This is usually only visible if the strand has gradient colors or transparent color and occurs on the same end with the flat tip. The appearance is as if multiple particles are getting stacked on eachother or are masking segments. But I can't make sense of what is happening. I'm really looking for some insight on how a strand works, and what the risks are in attempting to manipulate the strands along the curve. I get that underneath there is an array with positions that sync with an array of colors etc etc and that the positions are relative to the number of segments, what I don't understand is what is happening to the segment stamps when they are pushed off the curve. Any insight is welcome. -- Joey Ponthieux LaRC Information Technology Enhanced Services (LITES) Mymic Technical Services NASA Langley Research Center __________________________________________________ Opinions stated here-in are strictly those of the author and do not represent the opinions of NASA or any other party.
