may i ask how to make points created by “scatter” evenly distributed across a irregular surface?

and also, how to make all the scatter points located within the surface?

Thanks!

Here's another brute force way that brickers the geometry with the Divide SOP, over-scatters the points and then uses two Fuse SOPs to first snap and then cull the overlaps.

There's at least one school like the old school!

thanks a lot, Jeff!

If it's not too troublesome, can you advise on how to make the 2D triangulation happens only within the boundary as defined by the points?

drop a ClothRefine SOP between the Cookie and Scatter .

// it ‘ sleeps ’ inside the Cloth submenu //
except the things that cannot be seen , nothing is like it seems .

thanks, Zarti! your suggestion can create similar results.

What I want to know is how to get the triangulation based on the points we get from Jeff's approach, i.e. how to get rid of the surfaces highlighted below in yellow boundary as generated by the Triangulation 2D SOP…

Advice is appreciate!

pardon the delay . problems with internet from here

–
in the above post i just replied to the question ,

which i didnt connected it with the hip-s being shared to that point .

anyway ..

, i made few additions to the file you posted on post #3 ,

where you already solved the point 's distribution .

added few comments too about different small issues ( hopefully ) .


hope that helps ..

Hi, this is no longer necessary. Houdini's scatter node already contains this feature.
