I'm new trying to learn the basics of using the Wrangle sop. As a test I used an expression from the expression cook book in the Houdini docs. So there is a line and a point sop. In the position fields of the point sop the expressions are: X: cos(@ptnum *5) Y:@ptnum/400 Z: sin(@ptnum *5) this makes a spiral from the line. I want to do the same thing with the attribwrangle. So naively i tried: @P.x = cos(@ptnum *5); @P.y = @ptnum/400; @P.z = sin(@ptnum *5); What this did to the line was interesting. but was not the same as what the point sop did. I think if some one could explain how this is done it would help me a bit. thanks very much, b
