Oleg: The way I did it was to implement a QVariantAnimation-derived class that stores the QCamera's start &end positions, view centres, and up vectors. Then I just set the easing curve & the duration I want and call start(). Works great for my use case.
I haven't looked at the new Qt3D animation stuff, but I think its more geared towards animated models, not moving the camera? (In another case I use QPropertyAnimation directly to animate some arrow drawing in my scene which also works great and is easy to set up.) --- Andy Maloney // https://asmaloney.com twitter ~ @asmaloney <https://twitter.com/asmaloney> On Sat, May 6, 2017 at 1:46 PM, Oleg Evseev <ev.m...@gmail.com> wrote: > Hi, > > I'm looking for solution to get smooth orbit camera in qt3d.
