Experimental:Group POP

Summary

The Group POP lets you put sets of points or primitives into named groups so that you can then use the groups in other POPs, such as the Transform POP to affect only the elements of particular groups.

The groups are formed using 5 methods found on the Attribute, Thin, Pattern, Group and Bounding pages. You can choose to group points or primitives. On the Attribute page you can group based on the values of point or primitive attributes. On the Thin page you can group based on parameter-defined ranges, steps or randomly. You can group by Pattern Matching on the Pattern page. You can combine point or primitive groups on the Group page. You can include based on bounding ranges on any attribute on the Bounding page.

Conversions of groups can be done on the Edit page- renaming, conversion from point group to primitive group, etc.

Four of the grouping 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 group points in only a quarter of the space. Otherwise is common to build an attribute in a Math Mix POP and use it in the Group POP.

For pattern matching on the Pattern page: Pattern Matching.
