I need to move my geometry perpendicular to existing Normals.

Hello;

Please help : I need to move my geometry perpendicular to existing Normals.

 

 

Thanks.

Hi,

if you made a curve and that your normal is a « natural » normal (not tweaked manually in another wrangle), then when making your curve, output the tangentu attribute. It should be naturally perpendicular to N.

Otherwise, create your own perpendicular vector in a Wrangle using a cross product between your N and an up vector defined arbitrarily (in VEX should be something like v@perpN = cross(@N, up); and define up before like vector up = {0,1,0};)

Then same code as you have with N:

@P += ch(« offsetperp ») * v@perpN;
