Triangulation POP?

POPs
1

I am particularly impressed by the logical depth that these POPs operators can provide, sometimes they can be pretty straightforward and other time really abstract with all attributes that come into play. In this case i’m wondering if a Triangulation POP is something in WIP or there is something already doable with the currently POP operators and attributes.


Here is the system i did in SOP family, using trace for set some points in 3D space by a TOP picture and then apply the delaunay triangulation via Script SOP and mapping at the end the texture coordinates for TOP colours

Here instead my experiment to replicate it using just POPs nodes, like polygonize (for tracing), proximity (for connect points) and texturemap (to map colour from TOP).
Polygonize Proximity POP

The problems and ideas i encountered here was:

  1. The polygonize outputs lines, it would be nice to have the possibility to output just points or also other kinds of basic connections because i see, for example the movies, it could be a pretty hog operator and maybe is something that someone could decide after how connect all these points
  2. Proximity POP is really cool, but as i’m not properly a code programmer and i’m still didin’t catch how work properly with attributes, not sure if with this operator is possible to achieve some triangulation lines connection like delaunay or it is something that implies procedural steps before

Hi @Alaghast thank you for the feedback!

A triangulation POP is on our list, you might get some interesting looks with proximity POP but unfortunately not a proper triangulation.

Otherwise if you’d like points out of the polygonize you can use the convert POP to output point primitives or just points.
We’re planning to add more features to it.
Currently the outline is a set of lines which makes it hard to process further but if you’re converting to points you can remove points afterwards with a delete POP (thin page thin step for example)
