how to randomize point rotations "VOP SOP"

[Malcolm Zaloon]

Hi!

 

i´m trying to rotate each points randomically without stamping.

 

does exist a node to do this? anyway i wish to do it in VOP SOP too, to be more customizable...

 

i´m thinking "ICE WAY":

 

get points orientation -- >  add random rotation  -->   set point orientation

 

 

but even cant see "rotation" or orientation on GLOBALS! 

 

its crazy.. can anyone help me?

 

just for curiosity, but how to do the same in point_wrangle?

 

thanks!

and in wrangle it would be for example:

create spare parameter called anglevar, then

float anglevar = ch("anglevar");
vector angleranges = anglevar*fit(random(@ptnum), {0,0,0}, {1,1,1}, {-.5,-.5,-.5}, {.5,.5,.5});
@orient = quaternion(angleranges, 0);

Just set Orient attribute. Another example attached.

There exist only attributes that are necessary or inherited, so for Points there is only position by default.

Click RMB on any VOPSOP node and choose View VEX Code to see how syntax in VEX looks like.
