for non-animated scenes we have no monolothic mainloop. whenever something changes we trigger rendering. why is it this way: we don't render when nothing changes. this is a nobel goal. what we have if you want to have animation, the renderwindows provide a mod called

win.Time which is a Mod<DateTime>. So for animations the official recommendation is to Mod.map on this time. An example which refines this approach with higher precision timing could for example be found here: https://github.com/aardvark-platform/aardvark.rendering/blob/master/src/Examples%20(netcore)/10%20-%20NBodyCompute/Program.fs#L201For fixed timestep animations, one can do a much easier approach, as given here: https://github.com/aardvark-platform/aardvark.docs/blob/master/src/BackgroundColor/Program.fs#L39
is this approachable?
additionally the camera controller in rendering is kind of cool. as long as the animation should be active, frames are produced as fast as it can, and if you stop the animation the application falls back to "only render when again something changes"
like in "Fix Your Timestep!" article

this also is somehow related to a student project some time ago. in his aardvark based project he explored vr interaction techniques. https://philipperler.net/2017/06/13/haptic-feedback-in-room-scale-vr/
he was kind of the first trying out elm stuff in combination with VR and a physics engine behind
what he did there was roughly:
- have immutable world
- compute changes, flush to physics system
- physics run in physics engine
- flush back results into immutable world
@krauthaufen
will check in the evening
lol for the animation topic there is already a wiki entry which is empty: https://github.com/aardvark-platform/aardvark.docs/wiki#faq-aardvark-programming
haha I guess that wasn't a small question! So you fully recommend the Elm style in https://github.com/aardvark-platform/aardvark.media/blob/master/src/Aardvark.UI.Primitives/FreeFlyController.fs#L412 and https://github.com/ErlerPhilipp/VR_DA vs the pure rendering approach with adaptive blocks? I'll definitely dive in those!
watch out VR_DA is old. since then a lot developed in aardvark.media and aardvark.vr https://github.com/aardvark-community/aardvark.vr
and... it depends. if more and more ui and interaction comes in, media and elm style becomes more and more attractive
in the case you simply wanted to have a camera for a simple game or tech demo, pure rendering is ok
we have aardvark users who simply use aardvark.rendering and build a user interface with wpf for example around it. this is doable, but with more and more interaction you will find a more functional style (in contrast to mod.change and transact changes) more and appealing.
PRo3D (http://pro3d.space/) completely switched from pure rendering + ui code to purely media based which really turned out well since it is interaction focused. here, in samy the salmon @gnufu and @hyazinthh implemented a game. here the focus lies on rendering techniques https://github.com/gnufu/SamyTheSalmon
we should add blog links to some places
@haraldsteinlechner blog is build from here.. https://github.com/aardvark-platform/aardvark-blog-new
let me know if you need me to clarify anything
I've removed <DebugType>full</DebugType>, but still not sure. please review, maybe I miss some usages of full PDB? I know that full PDB is useful for unit-tests projects, because some of frameworks still uses it, e.g. for retrieving line numbers
I'm going to continue check examples then :)
aardvark helps to find UI bugs in Rider ;)
good evening
@haraldsteinlechner any chance to get aardvark-platform/aardvark.rendering#44 merged?
masterlisa is actually a semi-internal project by @gnufu
maybe we should ask her to move it somewhere else
What do you think about `
dotnet templates? Did I miss any features in experimental template?
