How to add implicit point normals in VEX?

[magneto]

Hi,

I know it's easy to do if you use VOPs. Just connecting N (input) to N (output) gives you normals the same way a Point SOP does.

But is there a way to replicate this in VEX? For example when using the Attrib Wrangle SOP?

@N = @N;[/CODE]

doesn't work. We should have the same capability in VEX.

Thanks

use Point Wrangle SOP not Attrib Wrangle SOP, attrib wrangle is based on CVEX so you need to tolerate some differences it has

if you want this for primitives however, you can use Attrib Wrangle, but like this http://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&p=133831#133831

Thanks anim, that worked wonderfully. Btw I checked your example for prim normals, but can that be done in VEX? I assume since you only showed VOPs, it's not possible.

[anim]

of course it is

you can use prim_normal() VEX function to get geometric primitive normal either from Point Wrangle, or if you require to use it on prims then Attrib Wrangle

I'll be off the Houdini for a long time, so no hip this time

Thanks anim, great to know that it's possible
