This will automatically scatter new points onto an incoming polygonal SOP. It works similar to the Scatter SOP in Houdini if anyone is used to that.
Just hook up a SOP and choose how many points per polygon you want. Make sure the incoming geo is polygons, not a mesh or something else.
You can also scale the density of where points get created by using the red color attribute on your incoming geometry. See attached .toe file as an example
I’ve now updated this to include a C++ plugin which works much faster than the tox, and also has more features like transferring position, color, and normals from the input geo onto the newly created points.
The c++ plugin has been improved to work with some bug fixes in the latest version of Touch
You can now use a custom attribute to control the density of points (opposed to only the color red in previous versions)
There are also 3 methods to control how the scattering works:
Quick: Simply scatters on every primitive. This is the fastest method, and works best when all triangle in the mesh are around the same size
The next two methods scatter try and give a uniform covering of points regardless of the size of the primitives. They both have pros and cons depending on your geometry.
Bin: The slowest method in most circumstances, but will give a consistent speed no matter the difference in size between the primitives.
If you have mostly large primitives, with only a few small ones, you may see a lack of points in the smaller primitives
Simple: Normally the fastest method, but will be much slower if your mesh has relatively small primitives with only a few large ones.
