Member Function Documentation
◆ clonePlacements()
template<typename I >
| Instance smtk::model::Instance::clonePlacements | ( | I | begin, |
| I | end, | ||
| bool | relate = true |
||
| ) |
Create a new instance duplicating a subset of this instance's placements.
This creates and returns a new instance. The new instance may have a different rule than the original as placement-subsetting may not be possible otherwise.
The begin and end arguments are iterators whose values are 0-based integer offsets into the sequence of placements.
The new instance will have an Instance::subset integer property listing the points selected from the original and will be related to the original as if it was a group member (i.e., with ArrangementKind::SUBSET_OF).
◆ divide()
template<typename Container >
| Container smtk::model::Instance::divide | ( | bool | merge = false, |
| Container * | clonesIncluded = nullptr |
||
| ) |
Divide an instance into several based on "subset" clones.
Once you are done creating subsets of an instance (via the clonePlacements method), you can call divideInstance() on the source instance (i.e., the parent of all the clones). It will inspect the clones and create new instances for all of the placements subsets (including the remainder of placements not in any subset).
If merge is true, then all clones marked as subsets of this instance will result in a single output instance. Otherwise, each clone will have its own output instance. The clones included in the division can be reported; if you pass in a non-null pointer for clonesIncluded, it will have the set of clones appended. Note that clonesIncluded is not reset by this method; any pre-existing entries will be preserved.
If divide is called on an instance with no clone-children, the returned set will be empty.
◆ generateTessellation()
| Tessellation * smtk::model::Instance::generateTessellation | ( | ) |
Apply rules (stored in properties) to recompute the tessellation for this instance.
This will always update the instance's tessellation whether it needs it or not. This method is called by EntityRef::hasTessellation() when no tessellation exists, so if you change properties that govern an instance's placements/transforms you may just remove the current tessellation and the tessellation will be created when asked for.
◆ merge()
template<typename Container >
|
static |
Merge two or more instances that have everything but placements in common.
If instances have the same prototype, rule, and other settings in common, this method will attempt to append their placements (and orientations, scalings, and colors) into a common output instance.
If instances cannot be merged, an invalid instance is returned.
NB: The current implementation will always merge instances into an instance with a tabular rule.
