Experimental:Primitive POP

Summary

The Primitive POP lets you manually create primitives. Primitives are made from points, so it takes an optional input POP, from which you can delete its primitives and create new ones. Then you can add a set of new points manually using blocks of sequential parameters on the Points page.

Next on the Primitives page you create new triangles, quads, lines, line strips and point primitives. When Method is By Set, and Primitive Type is Triangles, every 3 points creates a triangle. When Method is By Pattern, the points are selected by Pattern Matching, for example selecting Line Strip and pattern [0-9] creates a 10-point line strip.

On the Setup page the points can be given any new built-in or custom attributes.

On the Setup page you can remove the original primitives from the input POP by turning on turn on Delete Primitives + Keep Points.

On the Post page you can remove unused points in the result or turn them into point primitives.

When you create new primitives from the consolidated set of points, using sequential blocks you can create any combination of primitive types, and each primitive's vertices can be manually-specified or generated using numeric patterns.

See also Point POP which is basically the Points page of the Primitive POP.

You can re-connect a set of existing points by connecting a POP to the input, turning on Delete Primitives and Keep Points, adding no new points, then creating new primitives on the Primitive page.

To create a Point primitive per point, on the Primitive page, change Type to Point.
