Experimental:Delete POP

Summary

The Delete POP removes (or keeps) points or primitives using 5 methods found on the Attribute, Thin, Pattern, Group and Bounding pages. You can choose to delete points or primitives. On the Attribute page you can delete based on the values of point or primitive attributes. On the Thin page you can delete based on parameter-defined ranges, steps or randomly. You can delete based on patterns using Pattern Matching on the Pattern page. You can delete based on point or primitive groups on the Group page. You can delete based on bounding ranges on any attribute on the Bounding page.

Four of the methods let you build the logic using sequential blocks of parameters. For example on the Attribute page, one block selects P(0) > 0 and another that selects P(1) < 0 and ANDed together they will delete points in a quarter of the space. Otherwise is common to build an attribute in a Math Mix POP and use it in the Delete POP.

When deleting primitives, if points or vertices are no longer used, they are deleted. When deleting points, the vertices and primitives that use them can be deleted in part or entirely. Deleted points can cause like strips to be split, trimmed or deleted entirely.

For pattern matching on the Pattern page, see Pattern Matching.

Note: Deleting attributes can be done with the Attribute POP, the Select POP and all the Math POPs.

See also Group POP. The Field POP also can delete points.
