* Particles: reduce memory allocations by flattening a setGiuseppe D'Angelo2020-05-271-1/+2
| | | | | | | | | | | | | | | | | | | | When an affector acts on a particle, it will add it to a set of "seen" particles. This means an allocation, per particle, per frame. In Qt 6 the problem is less dramatic due to the new QHash implementation, which uses "wider" buckets, but in Qt 5 this is hundreds of memory allocations (and deallocations) per frame. Just reimplement a minimal flat-set API for this use case, and replace the QSet usages with it. On a testcase with 200 active particles, this reduces memory allocations from ~20'000 per second to 0 when the scene is "stable".

* Specify parameters of type registration in class declarationsUlf Hermann2019-09-261-0/+3
| | | | | | | | | | | | | | | | | | | | | Using this technique we can automatically register all necessary revisions and minor versions of a type, using the metaobject system. This greatly reduces the potential for mistakes and resulting incompatibilities between versions of imports. We assume that for each type we need to register all revisions of its super types and its attached type, and that the revisions match. That is, if you import version X of type A, you will also get version X of its attached type and of any super types. As we previously didn't take these dependencies into account when manually registering the types, a number of extra revisions are now registered for some types. Potentially, we can now generate the qmltypes files at compile time, using moc.

* Private export the ParticleSystem and AffectorAriel Molina R2015-11-241-1/+2
| | | | | | | | | | | | | | | | There are several special cases where the particle system is very useful for generating more than just eye candy. An example is a recreation of world weather/wind conditions as seen in http://earth.nullschool.net/ this patch allows for the implementation of similar systems. This patch does not adds features, just adds the macro Q_QUICK_PRIVATE_EXPORT in order to link the classes and derive custom C++ affectors for Qt Quick usage.
