Member Data Documentation

changing_haloes

std::set<int> halo::halo_impl::changing_haloes

private

Haloes that have an animation or expiration time need to be checked every frame and are stored in this set.

deleted_haloes

std::set<int> halo::halo_impl::deleted_haloes

private

Upon deleting, a halo isn't deleted but added to this set, upon unrendering the image is unrendered and deleted.

invalidated_haloes

std::set<int> halo::halo_impl::invalidated_haloes

private

Upon unrendering, an invalidation list is send.

All haloes in that area and the other invalidated haloes are stored in this set. Then there'll be tested which haloes overlap and they're also stored in this set.
