empty bounding box/invalid bb currently leads to stackoverflow. warning and ignore those?

MutableApp.toWebPart is the default entry used in most demos and applications. This also builds a renderer : Server with fileSystemRoot = Some "\" (https://github.com/aardvark-platform/aardvark.media/blob/master/src/Aardvark.UI/MutableApp.fs#L128).
On Windows this then performs a GetAllDrives and then tries to enumerate all files, but only to check if it is empty: https://github.com/aardvark-platform/aardvark.media/blob/master/src/Aardvark.Service/aardfs/FileSystem.fs#L189

There are scenarios with network drives that then result in blocking the application startup seemingly indefinitely (continuing after 10-12mintures). When the network drives that cause the issue are inspected with a windows file explorer it's also "looking" for a very long time without any progress.

I'm not sure if the root path "" should be considered valid. From my analysis, I would see two tasks:

1. It should be possible to deactivate this feature or even require it to be activated explicitly
2. The default behavior should no longer enumerate all drives + files on startup

currently cef.process etc uses a binding redirect for fsharp.core 0.0.0.0-5.0.0.0 - and fails to trigger since we have moved on to fsharp.core 5.0.2.

find way to deploy stuff. (e.g. spectrum atm just needs to be present)

• CheckBox inverted if started with false
• slider somehow flickers

Here is a minimal example:
https://github.com/aardvark-platform/aardvark.media/blob/main/src/Scratch/29%20-%20Garbage%20Collection/App.fs

The onClick handler closure holds temporary data that is then pinned at this line forever:

Currently the camera controllers miss some love:

• freely controller zoom does not work on mac
• arc ball works uses thread pool instead of animation based system
• orbit controller does not support pan

Currently only arc ballcontroller has a workaround wo work properly on Mac

@krauthaufen we need to review locking sheme

@ThomasOrtner

we are seeing ws problems in sleep/minimize scenarios. can we somehow try to reboot the connection on failure?

often this looks like:

[15:57:03 INF] WebSocket disconnected ConnectionError "Connection
reset by peer"
c: [Scene] n1047: destroyed

seealso pro3d-space/PRo3D#76

not to forget thx @ hyazinthh

The repository is superhuge, a lot of projects are poorly maintained. The idea is to move out examples and sketches which we find useful and sort them either into separate projects or aardvark.docs depending on what is best for each.

diagnostics and debugging was done here: aardvark-platform/aardvark.templates#2

this one seems to work:

the RawDownloader does not.

Seems like JpegDownloader uses blit in all cases. @hyazinthh something dangerous jumping to your eye?

seealso: SuaveIO/suave#711
as a workaround we currently set minThreads to at least 12.

When taking a screenshot via the screenshot service and the sampling size of the service and the targeted render node / control do not match the screenshot becomes garbage. Refreshing in quick succession returns a valid screeshot, leading to the assumption that the first frame is somehow broken.

• Union Case Tuples
• Domain type in module

need to use top.aardvark instead of document.aardvark? if so we need to find all places...

currently we cannot build on travis. must be something with outdated f# compiler: https://travis-ci.org/aardvark-platform/aardvark.media/builds/567939941

i disabled problematic one-liner for the moment and let us come back when compiler problems go away.

With special characters in assembly names like -, space etc resource names in GetManifestResourceNames become hard to analyse and work with. With LogicalName this can be controlled as such:

    <EmbeddedResource Include="resources/DragUtilities.js">
      <LogicalName>resources/DragUtilities.js</LogicalName>
    </EmbeddedResource>`

to support this it is need to detect resources with logical name and allow them through

It seems since version 5.3.0 FsPickler got rid of SourceLink.Embed.PaketFiles, that should .NET SDK projects' dependencies list cleaner.

see also aardvark-platform/aardvark.base#47

If a accordeon from UI.Primitives is nested in another one, the inner accordeon is broken: At a click it opens and immediatly closes again.
The issus seems to be that each accordeon issues a JS call to accordeon(), witch seems to affect all children too. The child accordeon then has the action attached twice.

We should finally add ClientValues to renderControl/scenegraph creation and add some mechanism to get these values into the model (beforeRender event maybe?)

• ViewportSize
• some sessionId
• transferMode (jpeg/raw)
• any other ideas?

behavior

When using a very small navigation sensitivity, e.g. 10^-5, the mouse interactions zoom, pan, and wheel zoom do not move the camera, while keyboard movement works fine.

expected behavior

super accurate pan and zoom movements with arbitrarily small movement intervals

my setup

let sensitivity = -5.0
let config = { 
  cam'.freeFlyConfig with
    panMouseSensitivity       = exp(sensitivity) * 0.0025
    dollyMouseSensitivity     = exp(sensitivity) * 0.0025
    zoomMouseWheelSensitivity = exp(sensitivity) * 0.1
    moveSensitivity           = sensitivity
    lookAtMouseSensitivity    = 0.004
    lookAtDamping             = 50.0
    }

move freefly camera along sky by pressing shift + w/s respectively

maybe fix in next diffgenerator release..

we currently have 2 camera controller implementations. the old one is deprecated. would be cool to fix all camera controller calls to use the new ones :)
