Hello, I`m working on Ink style effect. I would like to add point in between two (or more) nearest existing points, interpolate velocity and push new point slightly in vel direction, to have little bit more circular interpolation. That works well, better than point jitter or different cheap techniques. I would like to still fell motion from original sim. But I stuck on duplicated positions of some points, which is logical, other points can have similar near point. So I would like to add some counter, so if there were pair in past, don`t create new point. We are talking about millions of new points, so I need it as cheap and straight forward as possible. Basic idea, with some new points duplicated: float maxDistance = chf("maxDistance"); float minDistance = chf("minDistance"); int maxPoints = chi("maxPoints"); int nearPnts[] = nearpoints(0,@P,maxDistance, maxPoints); foreach (int pnts; nearPnts){ float distance = distance(point(0,"P",pnts), @P); if (distance > minDistance){ vector nearPos = point(0,"P", pnts); vector nearVel = point(0,"v", pnts); vector centerPos = lerp(nearPos, @P, 0.5); vector centerVel = lerp(nearVel, @v, 0.5); centerPos += centerVel * chf("pos_offset"); int newPoint = addpoint(0,centerPos); setpointattrib(0,"v",newPoint,centerVel); setpointattrib(0,"id",newPoint,@id*1000); setpointattrib(0,"newBorn",newPoint,1); } } I`m trying to add some counter ("tested") but seems like I cant read this attribute and my head is twisted I can see in spreadsheed, that "tested" has some range, so I need to connect with it. Any idea? Thanks a lot float minDistance = chf("minDistance"); int maxPoints = chi("maxPoints"); i@tested = 0; int nearPnts[] = nearpoints(0,@P,maxDistance, maxPoints); foreach (int pnts; nearPnts){ float distance = distance(point(0,"P",pnts), @P); setpointattrib(0,"tested",pnts,1,"add"); if (distance > minDistance && point(geoself(), "tested", pnts) == 1){ vector nearPos = point(0,"P", pnts); vector nearVel = point(0,"v", pnts); vector centerPos = lerp(nearPos, @P, 0.5); vector centerVel = lerp(nearVel, @v, 0.5); centerPos += centerVel * chf("pos_offset"); int newPoint = addpoint(0,centerPos); setpointattrib(0,"v",newPoint,centerVel); setpointattrib(0,"id",newPoint,@id*1000); setpointattrib(0,"newBorn",newPoint,1); } }

Hi, I have seen a lot of posts about exporting PRTs from Houdini but what I would like to do is import them into Houdini as points is there a way to do this? I have some nebulas saved out in PRT format and I wanted to do some experiments in Houdini with them. Thanks

Absorption like Krakatoa for Smoke Volumes
whodini posted a topic in Lighting & Rendering + Solaris!
Hey all, I'm curious if there is a way to render volumes such as billowy smoke with absorption . Here is a reference of absorption done in krakatoa http://assets.digitaltutors.com/dtv_/bison_courses/558/detailed_images/5.jpg I've tried setting up a few lights and tweaking the billowy smoke material but I can't seem to get the right look as shown in the reference. Any advice would help. Thanks!
