How do I know when to use a particular vector in a node.. i.e., Vector 1,2,3 or 4? I'm a bit confused about this.


Thanks

Hi,

It depends on the node but most SOP nodes use vector3 attributes. In VOPs it's a lot more varied.

I use vector2 when I need to store a two dimensional value, and vector for three dimensional value, and vector4 for four dimensional value. E.g: texture coordinates might be vector2, position or normal vector, and homogeneous coordinates or quaternions or matrix rows would be vector4.

Thank you both for the response, this helps a lot.
