Attribute transfer from one geometry object to another in Houdini

Attribute transfer from one geometry object to another

(based on distance) add a sphere move it slightly up add color node change to green add a grid add attribute transfer node and feed inputs conditions tab -> distance threshold: 1.5 blend width: 0.5 (add another color node for the grid) (there is also attribute copy for objects with same points/topo)

example with previous frame

(to draw a line on the grid with the sphere) delete the attribute transfer node add solver node connect the 2 color nodes with 1st and 2nd input then dive inside add attribute transfer node and feed input1 and input2 disconnect the output node from the previous frame node and feed the attributetransfer node then disconnect the first input1 node from the attribtransf and feed the the prevframe node
