mic Posted June 4, 2009 Share Posted June 4, 2009 hello! can you please tell me the math of these nodes - magnet (or it's simpler version bulge) SOP. i know the metaball's math, what's going on, all these functions (wyvill , etc) - but what's going on when i'm deforming the grid by metaball using bulge SOP? i see the effect but can't get the point what's the math of all of this - which coords the grid points get?.. thank you!

anim Posted June 4, 2009 Share Posted June 4, 2009 it seems to me that magnet is using metaball's weight to transform points relative to metaball's transform matrix bulge is using metaball's weight to push points from/to metaball's center Quote Link to comment Share on other sites More sharing options...
mic Posted June 4, 2009 Author Share Posted June 4, 2009 (edited) it seems to me thatmagnet is using metaball's weight to transform points relative to metaball's transform matrix bulge is using metaball's weight to push points from/to metaball's center thank you for answer! but when the metaball is at the zero height (it's center has the same y-coord as the grid) the points which are affected by metaball are deformed only in xz-plane. so, i don't understand the math of this motion.. ah, ok, sorry. yes, the magnitude is calculated using kernel function (wyvill etc), the distance by the distance and direction to metaball center - as you said.. i think i understood.. thank you!
