Sorry for finding your post late 😟 It may be too late now, but I tried implementing the biharmonic distance paper drive.google.com/file/d/1idWx_30R_VuXmIfLpyvkdl2ZCSak3x3D/view?usp=drive_link

@toadstorm fuck yesss that worked! was able to see the definition of the functions in there, found the inputindex call

for anyone curious, inputindex was the param i was looking for. the code for the action button: “` from kinefx.ui import rigtreeutils rigtreeutils.selectPointGroupParm(kwargs, inputindex=1) “` and the menu script: “` from kinefx.ui.jointselection import buildTransformMenu return buildTransformMenu(kwargs[‘node’], inputindex=1, is_motionclip=False) “`

gives you joint selection for the second input of your hda

Hi, I published a new hip that implements “Exact Evaluation Of Catmull-Clark Subdivision Surfaces At Arbitrary Parameter Values”😀 It computes the position and tangent plane after applying Catmull-Clark Subdivision from any position on a polygon.
I might implement application to boundary polygons someday😅

i wanted to copy a bunch of “characters” to points and be able to deform them with a rigpose after cloning. here is a hip file with my solution to updating the capture data so that the deformer works

@cdordelly Looks like the above Karma render is missing the reflection on backside, aka Enable Internal reflection on Render geometry settings LOP. It`s off by default….

had another thought about glow stuff… cops comes with a prefix sum node which makes what graphics people call “summed area tables” that let you look up box filters of any size pretty much instantly, so you can add up tons of them and get something p smooth <:cat_zuul:354000291768696834> even 100 layers stays pretty fast

i love it when you make a glow that’s realistic enough you start squinting because it feels like looking through dirty glass

since we were talking about dual rest fields for MPM i was dicking around in COPs and made a flowmap example for that, exactly the same concept but in texture space
